It is now common to see fingerprint sensors installed on devices such as smartphones. A fingerprint sensor installed on a smartphone can be used to verify the identity of the user. The fingerprint sensor can also be used as a data input or control mechanism for the smartphone. For example, the fingerprint sensor can detect a position of the finger on its surface and translate the position of the finger as an instruction to select a function of the smartphone or to navigate within the menus that are presented by the smartphone.

As fingerprint sensors are gaining recognition and acceptance from users, fingerprint sensors are finding use in numerous other devices such as, for example, smart cards, exerciser monitors or trackers, wearable items, household electrical appliances and industrial, automotive components, and Internet of Things (IOT) devices. Some devices, such as smart cards and IOT devices, have been limited to non-user interfaces or status indicators such as displays, speakers, LEDs, and audio signals with which the device can impart information to the user. Such devices may also have limited non-user input mechanisms for receiving user input due to the lack of a keyboard, switches, buttons, and levers.

Such devices, as well as computers, smartphones and the like, in which biometric sensors that authenticate the user are incorporated, such as fingerprint sensors, are sometimes generally referred to in this description as host devices,

Consequently, there is a need for a fingerprint sensor installed in a device with limited ability to provide feedback or obtain instructions from a user (hereinafter referred to as a limited device) wherein the fingerprint sensor provides input of data or a control mechanism for the device. The fingerprint sensor can have a primary purpose of verifying the identity of the user, but it can also function as a convenient way to control or enter data on the limited device.

For a biometric sensor, such as, for example, a fingerprint sensor, to operate properly, it is essential that a sufficiently detailed template (or multiple templates) of a user's biometric data (for example, fingerprint) be detected and stored during an enrollment process. The stored template (i.e. a biometric data verification template (e.g. fingerprint)) is used to compare with biometric image data generated by the biometric sensor (e.g. an image of a finger detected by the fingerprint sensor ) when the device is in general use. In an embodiment employing a fingerprint sensor such as the biometric sensor, a user is allowed to access a device if the detected image of the finger matches the stored fingerprint template. Consequently, it is important to acquire and store a fingerprint template of sufficient quality. If the stored fingerprint template is not of sufficient quality, the user may experience false acceptance and rejection at a high rate.

While the concepts described herein may be applied to various biometric sensors and associated biometric data and the biometric data verification templates, for purposes of illustration, and not for limitation, the examples are frequently described herein in the context of fingerprint sensors and fingerprint data (i.e. images).

For an enrollment process using a fingerprint sensor with a detection area smaller than the average finger surface, a template is constructed from multiple images of a finger. Specifically, the user is directed to repeatedly present their finger to the detection area of the fingerprint sensor until multiple images of sufficient quality are brought together to form the template. However, a fingerprint sensor installed on the limited device presents difficulties throughout the entire enrollment process. For example, limited feedback / input capabilities make it difficult to notify the user: (i) start the enrollment process, (¡i) repeatedly present their finger during the enrollment process, (i¡¡) that a sufficient number of images have been gathered, and (iv) that the registration process is complete.

Furthermore, existing solutions for enrolling a fingerprint on the limited device require the user to visit a secure location where the user will perform the enrollment procedure. For example, enrolling a fingerprint on a smart card requires the user to visit a secure location (such as a bank), create a template of the user's fingerprint on a separate device with the help of a trained agent, and upload the resulting template on the smart card. This conventional method of enrolling a fingerprint in the limited device is inconvenient for the user due to the required physical visit to a secured location. Additionally, this conventional method has come under a lot of scrutiny because it creates security risks due to the fact that the user cannot be sure that the user's fingerprint has not been lost or copied during the enrollment process at the secured location or that the fingerprint registered by the separate device is completely erased after the enrollment is completed. In addition, the accuracy of the verification may be compromised if the sensor used for user enrollment, that is, the sensor of a separate device, is different from the sensor used later for user verification, that is, the sensor of the limited device. .

ΊΛ / t / ZUZU / UUUZ

One objective of the embodiments described herein is to obviate at least some of the problems mentioned above with conventional methods of inscribing a fingerprint on a limited device. The systems, devices, and methods described herein provide a cost-effective and efficient process of enrollment of a user's finger on a limited device through a fingerprint sensor installed on the device - without the need for a separate device. to receive fingerprint images - which increases security and improves fingerprint matching precision for limited device.

In the context of the present description, a sensor element comprises an arrangement of one or more components configured to produce a signal based on a measurable parameter (eg capacitance, light / optical, heat / thermal, pressure, etc.), which Characteristics will vary based on the presence or absence of an object that is in local proximity to the sensing element. A fingerprint sensor will comprise an array of such sensor elements configured to produce a signal based on a portion of the surface of a finger positioned on or near the fingerprint sensor. The sensitivity of each of the sensor elements of the fingerprint sensor is such that the characteristics of the signal produced at each sensor element will vary based on the features of the surface of the finger portion placed on or near the array, and the varying characteristics of the signals produced at each sensor element can be combined or otherwise processed to form a data file with a real or virtual image of the fingerprint of the portion of the finger surface positioned on or near the array. .

Specific examples of such sensor elements may include, but are not restricted to, capacitive, optical, thermal, and pressure sensor elements. As an illustrative example, two types of capacitive sensor elements that can be used in a fingerprint sensor are mutual capacitance sensor elements and self-capacitance sensor elements. An arrangement of mutual capacitance sensing elements comprises a plurality of separate driver lines and a plurality of separate pickup lines arranged transversely to the driver lines and separated from the driver lines by a dielectric material. Each intersection of the pick-up lines and the drive lines constitutes a mutual capacitance sensing element configured to produce a signal indicative of a change in capacitance due to the presence or absence of a portion of an object that is in local proximity to the sensing element. mutual capacitance. An array of self-capacitance sensing elements comprises a first plurality of separate conductive lines and a second plurality of separate conductive lines arranged transversely to the first plurality of separate conductive lines. Each conductive line of the first and second plurality of conductive lines is configured to transmit a signal to the finger surface positioned in detectable proximity and receive a resulting signal. Consequently, each conductive line

ΊΛ / t / ZUZU / UUU / JO constitutes a self-capacitance sensing element configured to produce a signal indicative of a change in capacitance due to the presence or absence of a portion of an object that is in local proximity to the auto sensing element. -capacitance.

Also, Both sensor elements contemplated herein include silicon-based sensors in which the sensor elements are formed directly on a silicon semiconductor substrate and can form a 2-dimensional array of sensing pixels and non-silicon sensors in which the elements sensors are not arranged directly on a silicon semiconductor substrate (for example so-called off-chip sensors) but formed on a non-silicon substrate and are conductively connected to a remotely located control element, which may be a silicon-based semiconductor chip, such as an application-specific integrated circuit (ASIC).

While aspects of this description are presented in the context of specific types of sensor elements and fingerprint sensor configurations, it should be appreciated that implementations of these aspects are not necessarily limited to a specific type of sensor elements of fingerprint sensors. fingerprint described herein.

In some embodiments, the contact plates 108 further comprise one or more data transmission contacts that are different from the power transmission contacts that connect the smart card 104 to an external device configured to receive data from and / or transmit data to smart card 104. In this context, the data transmission contacts of the smart card 104 are the contacts that carry data transmitted to or transmitted from the smart card 104.

In some embodiments, the processing circuitry 110 and memory 112 may comprise a secure element module. In some embodiments, contact pads 108 may be part of the secure element module that includes processor 110 and memory 112, both of which are in electrical communication with contact pads 108. In an exemplary embodiment, the secure element module can adapt to the EMVCo® protocol commonly used in smart cards, and the contact pads 108 provide electrical contacts between the card 104 and an external card reader to provide power to the circuitry. card processing 110 and for reading data from and / or writing data to memory 112.

In various embodiments, the C6 contact, VPP, can, in accordance with ISO / IEC 7816-3: 1997, be designed as a programming voltage, such as an input for a higher voltage to program persistent memory (for example EEPROM ). In other embodiments, the C6 contact, VPP, can, according to ISO / IEC 7816-3: 2006, be designed as SPU, for either standard or

In the embodiments described herein, the contact plates 108 are only used to provide connection points via the one or more power transmission contacts, such as Cl VCC and C5 GND, to an external power source, and are not transmit data to or from the smart card 104 during an activation or enrollment process as described herein. In some embodiments, smart card 104 may comprise one or more power transmission contacts for connecting smart card 104 to a power source, without any additional data transmission capabilities as in a secure element module.

In some embodiments, the detection area 106 comprises a two-dimensional array of sensor elements. Each sensor element is a discrete sensing component that can be enabled depending on the function of the fingerprint sensor 102. In some embodiments, any combination of sensor elements in the two-dimensional array can be enabled depending on the function of the fingerprint sensor. Although the illustrated embodiment shown in FIG. 1 describes the fingerprint sensor 102 in relation to the smart card 104, this is not required and the fingerprint sensor 102, or other biometric sensor, can be incorporated into a different limited device in other embodiments. For example, other limited devices into which aspects of the technology described herein may be incorporated include exercise monitors, portable devices, household and industrial electrical appliances, automotive components, and Internet of Things (IOT) devices. .

Each driver line can thus be capacitively coupled to an overlapping pickup line through a dielectric layer. In such embodiments, the pickup lines can form one axis (e.g. X axis) of the array, while the drive lines form another axis (e.g.

ΊΛ / t / ZUZU / UUU / JO example Y axis) of the arrangement. Each location where a driver line and a pick-up line overlap can form a pair of impedance-sensitive electrodes whereby the overlapping portions of the driver and pick-up lines form opposing sheets of a capacitor separated by a dielectric layer or layers. This impedance-sensitive electrode pair can be treated as a pixel (eg an XY coordinate) in which a surface feature of the proximally located object is detected. The array or grid forms a plurality of pixels that can collectively create a map of the surface features of the proximally located object. For example, the sensor elements that make up the pixels of the grid produce signals that have variations corresponding to features of a fingerprint disposed on the particular sensor element and thus the pixels together with the circuitry that controls the sensor elements and that processes the signals produced by the sensing elements that include a processor and signal conditioning elements (i.e., circuitry that controls the sensor) that can be incorporated into an integrated circuit can map the locations where there are crest and valley features of the finger surface touching the sensor array.

An exemplary installation of a fingerprint sensor on a smart card is described in US Patent No. 9,122,901, the disclosure of which is hereby incorporated by reference.

In some embodiments, the detection area 106 of the biometric sensor, (eg, fingerprint sensor 102) installed in device 104 can be selectively configured to operate in five modes: (1) enrollment mode; (2) verification mode; (3) data entry mode; (4) control mode; and (5) unlock mode. In some modes, the user can select different modes through different interactions with the sensor, such as double tapping, holding, dragging up / down, and dragging.

ΊΛ / t / ZUZU / UUUZ left / right in the sensor area 106. In other embodiments, the sensor can be selectively configured in different modes by placing a data input device over the detection area 106. Data entry devices configured for different sensor modes of operation may include unique detectable features that, when detected by the sensor, will configure the sensor in a mode corresponding to the data entry device.

In the context of this description, A data entry device is any device that can be attached or otherwise coupled to a host device and thereby is coupled to a biometric sensor of the host device to enable a user to provide inputs to the host device through the sensor. biometric via data entry device features that allow the user to interface with the biometric sensor to provide control inputs or data inputs in addition of the particular biometric data that the biometric sensor is configured to detect. For example, in the examples described herein, the data entry device includes keys or buttons each of which is uniquely coupled to a fingerprint sensor of the host device so that a user who makes contact with any such key or buttons generates a single control entry or a single data entry corresponding to that key or button. Furthermore, in other examples described herein, the attachment or attachment of the data input device to the host device, or its removal, may by itself provide data input to the host device, for example, communicate that the data input device data has been attached or attached to, or removed from the host device, that the data entry device has or has not been properly positioned with respect to the biometric sensor to enable proper control or data entry by the user, or, as described above, to place the biometric sensor on one of a number modes of operation.

In some embodiments, when fingerprint sensor 102 is in enrollment mode, all of the sensor elements in the two-dimensional array of detection area 106 are activated in a fingerprint detection mode to produce signals - such as capacitance that has variations detect them corresponding to fingerprint features - grooves and ridges - in detection proximity to the sensor array (i.e. in physical contact with the sensor elements or in sufficient proximity to the sensor elements to produce signals corresponding to the fingerprint features) that together form an image of the fingerprint, and the circuitry that controls the sensor is configured so that multiple images can be put together from a user's fingerprint can, and possibly manipulate, to acquire a sufficient fingerprint template that can subsequently be stored in memory. An exemplary enrollment process is described in U.S. Patent No. 9,684,813, entitled Biometric Enrollment and Verification System and Method, the description of which is incorporated

ΊΛ / t / ZUZU / UUU / JO like this for reference. In some embodiments, the stored fingerprint template can be continuously updated based on the user's use of the fingerprint sensor over time.

In some modes, when the fingerprint sensor is in verification mode (also known as authentication mode), All of the sensor elements in the detection area 106 are activated in the fingerprint detection mode and the circuitry that controls the sensor is configured so that an image of the user's fingerprint can be acquired and compared to the template. fingerprint stored in memory to check whether the acquired fingerprint image sufficiently matches the fingerprint template. An exemplary verification process is also described in US Patent No. 9,684,813. An exemplary verification process is also described in US Patent Application No. 15 / 356,989 entitled Combination of Fingerprint and Device Orientation to Increase Security, the description of which is hereby incorporated by reference. Ideally, in both the enrollment mode and the verification mode, a finger should be placed centrally in the detection area 106 of the fingerprint sensor 102 to obtain the best image of the finger.

In some embodiments, when the fingerprint sensor is in control mode and data entry mode, the sensing elements in detection area 106 are activated in contact detection mode, data entry keys are operatively coupled to spatially distinct associated regions or detection area control areas to enable direct or indirect contact by a user's finger with each spatially associated distinct area, and the circuitry that controls the sensor is configured so that the user can input data through the detection area 106 by directly or indirectly placing a finger in selected spatially distinct associated control areas within the detection area 106 of the sensor. fingerprint sensor 102. That is, as opposed to the enrollment and verification modes, in which the sensor elements and the processor of the circuitry that control the sensor are configured to detect and map different fingerprint features of the finger surface, in the mode of contact detection for control and data input modes, The sensor elements and the circuitry that control the sensor can be configured to merely detect whether or not the sensor element is connected directly or indirectly by a finger surface and to distinguish a spatially distinct region of the sensor array in which the sensor resides. (the) element (s) contacted.

In both the control mode and the data entry mode, the detection area 106 can be divided into spatially distinct control areas dedicated to a specific command or specific data entry. The number and location of the spatially distinct control areas within the detection area 106 can be configured depending on the intended use.

In the unlock mode, the device 104 can maintain the data entry mode until the user enters a correct unlock code, whereby entry of the correct code unlocks the device 104.

In some embodiments described herein, when the fingerprint sensor is in the control mode and data input mode, a first portion of the sensor elements in the detection area 106 are activated in the contact detection mode, data entry keys are operatively coupled to distinct spatially associated regions or control areas of the first portion of the sensing area to enable direct or indirect contact by a user's finger with each distinct spatially associated area, and the circuitry that controls the sensor is configured so that the user can input data through the sensing area 106 by directly or indirectly placing a finger in selected, spatially distinct associated areas of control within the first portion of the sensor. detection area 106 of fingerprint sensor 102. In such modes, when the fingerprint sensor is in enrollment mode, only sensor elements located within a second portion of the two-dimensional array of detection area 106 different from the first portion and accessible to a user's finger can be activated in the fingerprint detection mode and the circuitry that controls the sensor it is configured so that multiple images of a user's fingerprint can be put together to acquire a sufficient fingerprint template that is stored in memory.

FIG. 2A is a top view of a detection area 106 of a fingerprint sensor 102 installed in a device with limited ability to provide feedback for or obtain instructions in accordance with some modalities. As shown in FIG. 2A, the detection area 106 includes indicia formed in the different quadrants (spatially distinct regions) of the detection area to facilitate data entry. In the verification or enrollment mode, the user can place a finger in the center of the detection area 106 to produce a fingerprint image. When the fingerprint sensor 102 is used in the data entry mode, each spatially distinct region can function as a data entry key, and the user can enter numbers (for example an activation code, such as a PIN code ) by tapping your finger into the numbered regions or areas 202A-D of the detection area 106. As shown in FIG. 2A, the detection area 106 can be divided into four separate spatially separate control areas 202A-D. In the illustrated embodiment shown in FIG. 2A, the user can place a finger in the upper left quadrant 202A, numbered 1, of the detection area 106. Consequently, the sensor elements located in the

ΊΛ / t / ZUZU / UUU / JO upper left quadrant 202A of detection area 106 can detect contact by the finger and the fingerprint sensor 102 can determine the location of the transmitting sensing elements and process the received signals to be an input by the user representing the number 1. In the embodiment shown in FIG. 2A, the user can place a finger in different quadrants 202A-D to enter the number 1, 2, 3, and 4 in any sequence. In another embodiment, the detection area 106 may be divided into more or less spatially distinct control areas. For example, there may be 6 spatially different control areas representing the numbers 1-6 or two control areas representing the numbers 1 and 2 (or the letters A and B). Consequently, the user is able to enter numbers corresponding to the spatially different keys of the sensor array in any sequence across the detection area. In another embodiment, all or part of the detection area 106 can be used as a spatially simple distinct control area dedicated to a Morse code type input by the user (for example, separate contacts, sequentially repeated, with the same distinct control area. spatially, each contact of a specific, different duration). The spatially distinct control area can be positioned in any portion of the detection area 106 or comprise the entire detection area 106. In another mode, any type of alphabetic characters, symbols or instructions (for example instructions for the device to try to connect to WiFi via WPS, disconnect / reconnect to WIFI, change the operating mode, pair with Bluetooth, etc.), or a combination of these could be entered in a similar manner depending on the desired operational function.

In some embodiments, the detection area 106 may be large enough that each spatially distinct control area 202A-D can detect an entire finger. Consequently, each spatially distinct control area 202A-D can independently verify a finger and be used to authenticate to access a device. For example, a radio key that can start 1 of 2 or more cars for a verified user can implement such spatially different control areas in its detection area. That is, a universal radio key configured to lock / unlock and start a car may include a fingerprint sensor large enough to accommodate 2, 3, 4, or more distinct regions specifically each large enough to have a subsequent image of one. fingerprint for verification. Each different region of the radio key can be configured so that the activation of the region corresponds to a different car. Thus, the radio key can be configured to allow an authorized user to operate any of 2, 3, 4, or more automobiles by touching a specific region of the sensor corresponding to a particular vehicle and providing a verifiable fingerprint.

In the verification or enrollment mode, the user can place a finger in the center of the detection area 106 to produce a fingerprint image. In the control mode, the user can control a device by placing a finger in spatially different control areas within the detection area 106 of the fingerprint sensor 102. In the illustrated embodiment shown in FIG. 2B, the fingerprint sensor 102 is installed in a portable exercise monitor. In the control mode, the user can pause or start monitoring by placing their finger in the appropriate quadrant 202A-D of the detection area 106 during normal operation of the portable exercise monitor. As shown in FIG. 2B, the upper left quadrant 202A of the detection area 106 is marked with a pause symbol, and the lower right quadrant 202D of the detection area 106 is marked with a play symbol. Consequently, the user can pause monitoring by placing a finger in the upper left quadrant 202A and start / end monitoring by placing a finger in the lower right quadrant 202D.

In some embodiments, regions 202B and 202D may be non-functional, reserved for other manufacturer-defined functions, or reserved for certain user-defined functions.

As shown in FIGS. 2A and 2B, spatially different control areas may be visible to the user. In some embodiments, the dividing lines 204A-B (thin crossed lines) may be indicated in the detection area 106 and visible to the user continuously during operation of the fingerprint sensor 102. In other embodiments, an elliptical profile 206 may be indicated in detection area 106. In such embodiments, elliptical profile 206 is centered in detection area 106 to motivate the user to place a finger centrally in detection area 106 when using fingerprint sensor 102 in enrollment or verification mode. In some embodiments, different profiles may be used for indication instead of elliptical profile 206. In some embodiments, the indication of dividing lines 204A-B and elliptical profile 206 can be implemented through the use of distinctive colors, lines, and textures achieved through printing and / or engraving. In some embodiments, a suitably chosen coating that does not adversely impact the sensitivity of the detection area 106 can be used to indicate spatially distinct control areas.

In some embodiments, an OLED display may operate as the fingerprint sensor 102. In such embodiments, the fingerprint sensor 102 may display the indication of the dividing lines 204A-B and the elliptical profile via the OLED display.

FIGS. 3A and 3B illustrate an application of a data input device in the form of an overlay 302 placed over the detection area 106 of the fingerprint sensor 102 installed on a smart card 104 according to some embodiments. As shown in FIGS. 3A and 3B, the overlay 302 can be placed over the detection area 106 of the fingerprint sensor 102 of the smart card shown in FIG. 3A. In some embodiments, an external battery or power source may be connected to one or more of the contact plates 108 to provide power for the operation of the fingerprint sensor 102. In some embodiments, the coating 302 is a label with adhesive on the back or film temporarily and removably placed over a portion of the card 104 including the detection area 106 of the fingerprint sensor 102, as shown in FIG 3B. In some embodiments, repositionable adhesives provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik can be applied to coating 302 to be temporarily placed on the portion of the card 104 including the detection area 106. The overlay 302 may indicate the spatially distinct control areas of the detection area 106 through perforated holes 304A-D that define four data entry keys, each associated with a spatially distinct control area of the detection area 106. In some embodiments, the drilled holes 304A-D can provide a zoning effect without impacting the sensitivity of the fingerprint sensor 102. As shown in FIG. 3B, the four perforated holes 304A-D indicate the spatially distinct control areas in the detection area 106 of the fingerprint sensor 102 corresponding to the numbered keys 1, 2, 3, and 4. In other embodiments, there may be a greater number or fewer holes punched depending on the function of the fingerprint sensor. In some embodiments, the user can enter a numerical activation code (also referred to as an authentication code) by placing a finger on the spatially different control areas in a sequence according to the activation code, thus unlocking and placing the card smart 104 in enrollment mode. In some embodiments, instructions may be provided on the overlay 302 to guide the user, and each spatially distinct control area may be labeled or numbered. For example, the user can call a phone number listed on overlay 302, such as, a 1-800 phone number, to retrieve the numeric activation code to be entered or the user can receive an SMS text on their personal cell phone. from a secure financial institution. Once the user retrieves the numerical activation code, the user can enter the code by connecting the card 104 to a power source and placing a finger on the spatially numbered distinct control areas in a sequence according to the code, unlocking so the card. Consequently, only authorized end users can

ΊΛ / t / ZUZU / UUU / JO unblock a blocked card 104 supplied through a public mail system. In some embodiments, a user may enter a gesture on the detection area 106, such as by sweeping a pattern to stitch together a plurality of spatially distinct control areas in a predetermined sequence.

In some embodiments, the overlay 302 may comprise a single perforated hole defining a data entry key, the one data entry key is associated with a control area spatially different from the detection area 106 configured to receive a data entry. Morse code type by the user. In such embodiments, the user can retrieve the activation instruction and activation code entry in accordance with the retrieved instruction by making one or more separate sequential contacts of varying durations, specified with the enter key. For example, the user can call a specified telephone number to be instructed to use a finger to press down on the data entry key when the user hears a beep and lift the finger when the beep ends. This process could be repeated for one or more additional beeps of varying lengths. In some modalities, the user can receive the Morse code activation instructions through an SMS text or a downloadable audio file.

In some embodiments, contact with the sensor can be determined by the fingerprint sensor 102 and the circuitry that controls the sensor by scanning the entire detection area 106, canceling out any background noise, and calculating an average measurement on each element. sensor to determine a signal that exceeds a threshold that indicates contact with the sensing element. If the sensing elements that record a signal that exceeds the threshold are confined to a distinct spatially discrete region - meaning that the user has touched only one key - the contact is recorded as a valid input - not necessarily the correct input, which is determined by the sequence provided by the code, but merely that valid input was received. If the sensor elements that record a signal that exceeds the threshold are not confined to a discrete spatially distinct region - meaning that the user has simultaneously touched more than one key - the contact is recorded as an error. In some embodiments, the system can be configured to register multiple touches as a valid entry to increase the number of possible entries from which a unique activation code can be constructed. For example, while contact with key 1 and key 2 constitutes two possible valid entries, simultaneous contact with both of key 1 and key 2 can constitute a third possible valid entry.

In some embodiments, the fingerprint sensor 102 can detect an absence of a finger positioned on the detection area 106 - that is, the absence of a signal - to distinguish between each data entry by the user.

After the activation code has been successfully entered, the liner 302 can be removed and discarded when it is no longer used. In some embodiments, a small tab 310 protrudes from one side or corner of the liner 302 so that the user can remove the liner 302 with ease. Care must be taken, however, to ensure that the card is not inadvertently removed from the power source in the process of removing the coating 302 from the card 104. In some embodiments, the small tab 310 may be located at an edge or corner of the liner 302 which encourages the user to remove the liner 302 in a direction that moves toward the power source, rather than pulling away from the source. to avoid separating the card from the power source.

As shown in FIG. 3B, the card 104 may include an LED 308 or other indicator element, and the overlay 302 may comprise a drilled hole 306 positioned on the LED 308 that allows the user to see the LED when the overlay 302 is temporarily placed on a portion of the card. 104 including detection area 106 and LED 308. LED 308 may light and blink to communicate various instructions and confirmations to the user. For example, the LED can display: (1) a solid light for 2-3 seconds indicating that the fingerprint sensor 102 is powering up when the card 104 is properly connected to a power source; (2) a single blink indicating that a valid user input has been made; (3) short repeated blinks indicating no user input (ie invalid input attempt); (4) solid light for a long period of time, for example 5 seconds, indicating that a code or data entry made by the user is correct; (5) long repeated rapid flashes indicating that a user code or data entry is incorrect; and (6) rapid repeated flashes when the user has exhausted a maximum number of entry attempts without correctly entering the activation code. In another embodiment, LED 308 can be multi-color. Consequently, LED 308 can flash different colors in a variety of combinations to communicate the various instructions and confirmations described above.

In some embodiments, card 104 may include more than one LED 308 or other indicator element. In such embodiments, more than one LED 308 may flash different colors to communicate the various instructions and confirmations described above. For example, when there is a red LED and a green LED, the following states can be indicated: (1) both LEDs are off until power is applied to the card; (2) when power is applied, if a fingerprint template is already enrolled on the card, the green LED is on solid; (3) if the fingerprint template is not enrolled on the card, it initiates an enrollment sequence described by the following steps 4 to 10; (4) the green LED blinks until a finger is placed on the sensor, or

ΊΛ / t / ZUZU / UUU / JO until a finger that remains on the sensor from the previous image capture step is removed from the sensor and then put back on top; (5) the green LED turns off when the finger is on the sensor and an image is captured; (6) if the detected finger sensor coverage is less than a threshold denoting poor image capture, the red LED turns solid for 1 second and the sequence returns to step (4); (7) if the detected sensor coverage is greater than or equal denoting the probability of a good image capture, both LEDs remain off while the captured image is evaluated to determine if it should be written; (8) if the image is enrolled, the green LED is solid for one second, otherwise if the image has not been enrolled, the red LED is solid for one second; (9) Steps 4-8 are repeated until a sufficient fingerprint template is created; (10) The green LED turns solid to indicate that the process has been completed successfully. In some embodiments, the enrollment sequence (also referred to as the enrollment mode) can be terminated after the fingerprint template is stored. In some embodiments, a flexible display such as an OLED may be incorporated into the body of the card 104 to provide the user with detailed visual and textual feedback.

In some embodiments, the fingerprint sensor 102 may include a display or a sound emitting unit, such as a horn or vibrator, to provide feedback to the user such as a status indication. In such embodiments, the overlay 302 may be profiled or contain a cutout so that the user can view the display and receive the status indication. In some embodiments, an OLED display can operate as the fingerprint sensor. In such embodiments, the fingerprint sensor 102 can provide feedback to the user such as a status indication via the OLED display.

FIGS. 4A to 4C are top plan views of a data entry device in the form of a coating 402 temporarily placed over the detection area 106 with different configurations of drilled holes 404A-D formed in the coating 402 according to some embodiments. As shown in FIGS. 4A through 4C, the drilled holes 404A-D are defined spaces, such as holes or windows, in the liner 402 surrounded by material. In some embodiments, the surrounding material prevents a finger from contacting the underlying sensing area 106 when a finger is placed on the coating 402. In some embodiments, the drilled holes 404A-D may have a circular, oval, square, or profile. polygonal. The punched holes 404A-D may define data entry keys associated with spatially distinct control regions of the detection area 106 used to enter data or otherwise control a device in which the fingerprint sensor 102 is installed. In the embodiments illustrated in FIGS. 4A to 4C, only a portion of each drilled hole 404A-D covers a portion of the detection area 106, and the distinct regions

ΊΛ / t / ZUZU / UUU / JO spatially of the detection area corresponding to the drilled holes 404A-D do not collectively constitute the entire detection area 106. Technically, a spatially distinct region can be defined by a single sensor element (pixel) as long as the data input device (for example overlay) is configured so that the contact of a user with a particular key of the data input device data corresponding to the spatially distinct region is detected in that single sensor element. This allows the fingerprint detection area 106 and overlay 402 to provide a larger effective touch input area (as shown by dotted lines 405 in FIG. 4A) for the user while maintaining accurate finger detection.

FIG. 4A illustrates one embodiment of drilled holes 404A-D in which drilled holes 404A-D are outlined as circles and located at each corner of the detection area 106. As shown in FIG. 4A, each of the drilled holes 404A-D defines a circular sector detection area 406A-D for each associated spatially distinct control area. The circular sector detection areas 406A-D are responsible for detecting a finger when placed over the corresponding hole 404A-D. In some embodiments, the drilled holes 404A-D are spaced an optimal distance apart so that the fingerprint sensor 102 can distinguish which control area spatially distinct from the detection area 106 a user is touching while maintaining the largest area for each. 406A-D circular sector detection area. As described above, in one embodiment, the fingerprint sensor 102 can recognize and reject any data input when the user simultaneously places a finger on two or more spatially different control areas of the detection area 106. In some embodiments, it is 8mm diameter circles can be used for drilled holes 404A-D.

In some embodiments, the fingerprint sensor 102 may not scan every sensor element in the two-dimensional array of sensor elements in the detection area 106, which can improve the sensor response time in the data entry mode. For example, fingerprint sensor 102 can scan each sensor element in detection area 106 not covered by coating 402. As shown in FIG. 4A, the fingerprint sensor 102 can recognize the exposed detection areas defined by the circular sector detection areas 406A-D. Consequently, the fingerprint sensor 102 can scan the sensor elements located within the circular sector detection areas 406A-D.

In some embodiments, since the sensor 102 does not require the same resolution in a data entry mode as is required in a fingerprint detection mode, the fingerprint sensor 102 can scan every other, or every third (or more ) sensor element in a row or column of the two-dimensional array of sensor elements in the detection area 106 (or in the

ΊΛ / t / ZUZU / UUUZ JO detection areas 406A-D), which can improve the response time in data input mode.

In some embodiments, each drilled hole 404A-D can be placed on the edge of each corner of the detection area 106 so that each circular sector detection area 406A-D is reduced to a sensor element, which can improve distinguishing. between each control area spatially distinct from the detection area 106. In such embodiments, each control area spatially distinct from the detection area 106 comprises a sensor element responsible for detecting a finger when positioned over the corresponding hole 404A-D.

FIG. 4B illustrates another embodiment of drilled holes 404A-D. As shown in FIG. 4B, the drilled holes 404A-D are outlined as squares with rounded corners and located at each corner of the detection area 106. Consequently, each of the drilled holes 404A-D forms a square detection area with a round corner 408AD. The rounded square configuration of the drilled holes 404A-D allows a larger portion of the detection area 106 to be dedicated to each associated spatially different control area compared to the circle configuration. In some embodiments, each of the rounded corners may comprise a length and width of 8mm, for example.

In some embodiments, the fingerprint sensor 102 can scan only the sensor elements located within the detection areas 408A-D and can scan every other, or every third (or more) sensor element in a row or column of the two-dimensional array. of sensor elements in the detection area 106 (or in the detection areas 408A-D), which can improve the response time of the sensor in data entry mode.

In some embodiments, each drilled hole 404A-D can be placed on the edge of each corner of the detection area 106 so that each square detection area with a round corner 408A-D is reduced to a sensor element, which can improve the distinction between each control area spatially distinct from the detection area 106 ,. In such embodiments, each control area spatially distinct from the detection area 106 comprises a sensor element responsible for detecting a finger when positioned over the corresponding hole 404A-D.

FIG. 4C illustrates another embodiment of drilled holes 404A-D. As shown in FIG. 4C, the drilled holes 404A-D are outlined as circles and located on each side of the detection area 106 - opposite each corner. Consequently, each of the drilled holes 404A-D forms a circular segment detection area 410A-D on either side of the detection area 106. The configuration of the drilled holes 404A-D shown in FIG. 4C has the advantage that it provides a large detection area for each spatially different control area, while providing a minimum distance between each of the different areas.

In some embodiments, the fingerprint sensor 102 scans only the sensor elements located within the detection areas 410A-D and may scan every other, or every third (or more) sensor element in a row or column of the two-dimensional array of sensor elements in the detection area 106 (or in the detection areas 410A-D), which can improve the response time of the sensor in data input mode.

In some embodiments, each drilled hole 404A-D can be placed on the edge of each side of the detection area 106 so that each circular segment detection area 410A-D is reduced to a sensor element, which can improve the distinction between each control area spatially different from the detection area 106 ,. In such embodiments, each control area spatially distinct from the detection area 106 comprises a sensor element responsible for detecting a finger when positioned over the corresponding hole 404A-D.

FIGS. 5A and 5B show a data input device in the form of a frame 502 used in relation to the detection area 106 according to some embodiments. As shown in FIGS. 5A and 5B, a frame 502 with punched holes 506A-B may be aligned with the fingerprint sensor 102. In some embodiments, the number, profile, and size of the punched holes 506A-B may differ as described above in relation to FIGS. 4A to 4C. As shown in FIG. 5A, frame 502 may be positioned on fingerprint sensor 102 with a hinge that allows frame 502 to flip open and reveal the entire detection area 106 for fingerprint detection. As shown in FIG. 5B, the frame 502 can be flipped upside down to indicate the spatially distinct control areas 504A-B wherein the spatially distinct control areas 504A-B depend on the detection area 106 revealed through the drilled holes 506A-B in the frame 502. In some embodiments, frame 502 may be positioned on the device containing the fingerprint sensor 102. In such embodiments, frame 502 is appropriately positioned in the device so that frame 502 covers detection area 106 when flipped down and indicates spatially distinct control areas as shown in FIG. 5B. In some embodiments, frame 502 may enable a user to control the device containing fingerprint sensor 102 by placing a finger in spatially distinct control areas 504A-B. For example, the user can place a finger on a wireless protected setup (WPS) key 504A to connect the device to WiFi or place a finger on a reset key 504B to reset the device. In other embodiments, frame 502 can be positioned on the fingerprint sensor or the device containing the fingerprint sensor with a slider so that frame 502 can slide back and forth in direction A to hide or reveal detection area 106.

In some embodiments, a detectable feature of frame 502 may be detected by one or more sensing elements of detection area 106 to determine that frame 502 is upside down and to put detection area 106 into data input mode to detect. contact with one of the spatially different keys 504A or 504B. In some embodiments, the detectable feature may be a metal, metallic paint or conductive ink, conductive polymer, or any conductive coating added to the side (bottom) of frame 502 that comes into contact with detection area 106 when frame 502 is flipped closed. . In such embodiments, metal, metallic paint, conductive ink, conductive polymer, or any conductive coating allows the fingerprint sensor 102 to detect whether the frame 502 is open or closed. The fingerprint sensor 102 can change modes depending on whether the frame 502 is open or closed. For example, when the frame 502 is open and the entire detection area 106 is revealed, the fingerprint sensor 102 no longer detects the metal, metallic paint, or conductive ink and enters a fingerprint detection mode, such as, for example, verification mode or enrollment mode. As another example, when frame 502 is closed, fingerprint sensor 102 detects metal, metallic paint, or conductive ink and enters a mode depending on the configuration of the metal, metallic paint, or conductive ink. In some embodiments, conductive ink can be added to the background of frame 502 in accordance with a predetermined pattern so that fingerprint sensor 102 can detect and recognize the pattern and enter a particular mode based on the pattern. In some embodiments, frame 502 may comprise one or more metallic dome switches that provide tactile feedback to the user. In such embodiments, an input by the user is detected by the detection area 106 when finger pressure is applied to a surface of the dome switches. For example, the one or more metal dome switches can look like the typical keypad on a microwave oven.

In some embodiments, a frame may include more than one flipped data input device, each providing different functionality. Each data entry device can be provided with a different detectable feature - for example a conductive ink applied in a unique pattern - to be detected by the sensor and to configure the sensor in a different data entry mode corresponding to the specific device. data entry.

FIGS. 6A to 6C illustrate the use of a data input device in the form of a double layer coating 602 that can be temporarily placed over the detection area 106 in accordance with some embodiments. As shown in FIGS. 6A to 6C, the double layer coating 602 comprises an upper layer 604 and a lower layer 606, wherein the bottom of the lower layer 606 contacts the surface of the detection area 106

ΊΛ / t / ZUZU / UUU / JO when the double layer coating 602 is placed over the detection area 106. As shown in FIG. 6B, top layer 604 comprises one or more drilled holes 608A-D. In some embodiments, the edge surface surrounding each drilled hole 608A-D may be slightly raised so that a user can feel the circumference of the hole when placing a finger on it. As shown in FIG. 6C, the bottom layer 606 is unperforated and is made of a thin web of material according to some embodiments. The surface of the bottom layer 606 may be colored or include printed indicia, a textured pattern, or a design aligned with the drilled holes 608A-D to indicate spatially distinct control areas to the user. In some embodiments, the bottom layer material 606 can be a thin polymer, typically no more than 50-100 microns in thickness. The material and thickness of the lower layer 606 should be such that it does not negatively impact the detection of contact with the detection area through the drilled holes 608A-D.

As shown in FIG. 6C, numbers or other indicia can be printed on the surface of the lower layer 606. The position of the numbered portions 610A-D on the surface of the lower layer 606 corresponds to the position of the punched holes 608A-D in the upper layer 604. Consequently, when the upper layer 604 and the lower layer 606 are combined to form the double layer coating 602, the portions numbered 610A-D indicate the location of the spatially distinct control areas through the drilled holes 608A-D of top layer 604. In some embodiments, indicia may be printed on top layer 604. In such embodiments, the indicia can be printed substantially near the punched holes 608A-D so that a user can associate a separate indicia for each punched hole 608A-D.

FIG. 7A illustrates an embodiment of a data input device in the form of an overlay 702 with complex perforation patterns used in connection with the detection area 106 of the fingerprint sensor 102. In some embodiments, the overlay 702 with arranged perforations in detectable patterns, i.e. perforation patterns 704, it can be used to provide a more secure mechanism for the fingerprint sensor 102. For example, patterned overlay 702 can be shipped to a user and temporarily placed over detection area 106 to be used as a stencil for a quick response or QR® code (or other 2D detect code), where the pattern Complex perforation can constitute a unique pattern associated with the user or the device containing the fingerprint sensor. In some embodiments, the coating 702 and the device in which the fingerprint sensor 102 is installed can be provided. When the user places a finger 701 over the complex perforation pattern coating 702, preferably which contacts all perforations 704 simultaneously, the fingerprint sensor 102 only detects the

ΊΛ / t / ZUZU / UUUZ contact with the portions of the detection area 106 exposed through the complex perforation pattern 704. Consequently, the complex perforation pattern coating 702 can function as an access code or key to access or otherwise use the functions of the device in which the fingerprint sensor 102 is installed. For example, touching the detection area 106 through the complex perforation pattern coating 702 could put the device into a particular mode of operation, or unlock special functionalities such as putting the fingerprint sensor 102 in enrollment mode, or perform a factory reset of the device.

In some embodiments, complex perforation patterns 704 in coating 702 can be converted to a digital representation that is stored in device memory. In such embodiments, the device may require the user to touch the detection area 106 through the complex perforation pattern coating 702 to initiate a fingerprint enrollment process. For example, when the user places a finger 701 on the complex perforation pattern coating 702, the fingerprint sensor 102 can detect the finger 701 through the complex perforation pattern 704 and compare the detected image with the stored digital representation of the complex perforation pattern 704. In some embodiments, if the detected image does not match the stored digital representation of the complex perforation pattern, the device could shut down to prevent further access by the user or issue a warning. Depending on the level of security required, the degree of match indicating success or failure could be made more or less strict.

Another application of complex perforation pattern coating 702 is to determine piracy or tampering with products. In some embodiments, the devices can be sold with the complex perforation pattern coating 702 positioned over the detection area 106. In such embodiments, the devices can be enabled only the first time when a user places a finger on the detection area 106 through the complex perforation pattern coating 702, thereby assuring the user that the product is genuine and / or has not been altered. In the embodiments described in relation to FIG. 7A, complex perforation pattern coating 702 is used in combination with finger 701 touching a fingerprint sensor 102. However, the complex perforation pattern concept 704 can be generally applied to any biometric sensor, eg iris, retina, palm print, or to any device with a touch screen in alternate modes.

FIG. 7B illustrates a data input device in the form of an overlay 706 with printed patterns 708 used in connection with the detection area 106 of the fingerprint sensor 102 according to some embodiments. In such embodiments, the coating 706 comprises a pattern 708 of conductive material printed thereon. Pattern 708

ΊΛ / t / ZUZU / UUU / JO can be arranged in detectable patterns and can be used to provide a more secure mechanism for the fingerprint sensor 102.

For example, patterned overlay 706 can be given to a user and temporarily placed on top of detection area 106 to be used as a quick response or QR® code (or other detectable 2D code), where the printed pattern 708 may constitute a unique pattern associated with the user or the device containing the fingerprint sensor. In some embodiments, the coating and the device in which the sensor is installed can be given separately. When the patterned overlay 706 is placed on top of the detection area 106 of the fingerprint sensor 102 the printed pattern 708 comes into contact with the surface of the detection area 106, and the sensor elements of the fingerprint sensor 102 which spatially correspond to elements of pattern 708 that detect contact with printed pattern 708. Accordingly, the patterned overlay 706 can function as an access code or key to access or otherwise utilize the functions of the device in which the fingerprint sensor 102 is installed. For example, placing the detection area 106 in contact with the printed design overlay 708 can put the device into a particular mode of operation or unlock special functionalities, such as putting the fingerprint sensor 102 in enrollment mode, or performing a factory reset the device.

FIG. 8 illustrates a calibration method for the fingerprint sensor 102 according to some modalities. In some cases, a data entry device such as a cover or frame, as described in FIGS. 3A through 7B, it may be misaligned with the detection area 106. In the illustrated embodiment shown in FIG. 8, a data entry device in the form of an overlay 802 is temporarily positioned over the detection area 106 where the overlay 802 is misaligned with the detection area 106. In some embodiments, the overlay 802 may comprise detectable features and the location of such features as detected by sensor 102 can indicate the position of coating 802 with respect to detection area 106. For example, a vertical conductive line 804A and a horizontal conductive line 804B can be applied (eg with conductive ink) to the back surface of coating 802 to form thin cross lines in the center of coating 802. Fingerprint sensor 102 can be configured to wait for conductive lines 804A-B to be placed over detection area 106 in a predetermined position, in this case a vertical and horizontal line 806A-B through the center of the detection area. 106. When an overlay 802 is placed over the detection area 106 and the conductive lines 804A-B in the overlay 802 are not placed over the expected position, as shown in FIG. 8, the fingerprint sensor 102 detects misalignment. In some modalities, the

ΊΛ / t / ZUZU / UUU / JO fingerprint sensor 102 can detect a margin of misalignment based on a distance between the 804A-B conductive ink on the 802 coating and the expected 806A-B placement. In such embodiments, if the fingerprint sensor 102 detects a margin of misalignment that exceeds a predetermined threshold, the user can be alerted to replace the overlay 802 in a more precise manner, for example with a flashing LED indicator. If the margin of misalignment does not exceed the predetermined threshold, the fingerprint sensor 102 can factor the margin of misalignment in the processing of input received from a finger through the overlay 802. Specifically, the fingerprint sensor 102 can adjust the expectation of the position of the exposed touch areas based on the detected margin of misalignment.

In some embodiments, the thin cross lines can be replaced by a single detectable point or a small cross at the centroid of the coating. In some embodiments, unique detectable patterns can be formed in the configured coating to impart information to the sensor. For example, each of the conductive lines 804A-B that form the crossed thin lines can be formed from a unique pattern of dots, dashed lines, and spaces. The unique pattern can be detected, similar to a barcode pattern, and correlated with a specific instruction or other information. For example, the master can authenticate the coating to confirm that the correct coating is placed on the device. In some embodiments, different overlays can be used for different data entry functions. In such embodiments, a unique detectable code may correspond to a particular functionality to thereby cause the fingerprint sensor to be configured in the correct data entry mode.

In some embodiments, the conductive ink 804A-B on the coating 802 can allow the fingerprint sensor 102 to detect if the coating 802 has been removed. In such embodiments, the fingerprint sensor 102 can be configured not to enter an enrollment mode until the coating 802 has been removed. In some embodiments, a variety of different coatings - each corresponding to a different data entry functionality - may be temporarily placed over the detection area 106 to operate the fingerprint sensor 102. Each coating may have a conductive ink pattern. that can recognize the fingerprint sensor 102. In some embodiments, the use of certain coatings in relation to the fingerprint sensor 102 is restricted. For example, the fingerprint sensor 102 may recognize a restricted coating based on the dedicated conductive ink pattern and deny access for that particular coating.

FIGS. 9A through 9C illustrate an embodiment of a battery powered power source 902 in use with the fingerprint sensor 102 installed on the smart card 104. In some embodiments, the power source 902 (also referred to as a power source that does not transmit data) is powered by a suitable 905 battery, such as a small LR44 cell. Alternatively, the power source 902 can be based on any suitable power element, such as solar or harvested power. In some embodiments, power source 902 may comprise a plug, such as a USB plug, to allow connection of power source 902 to a main power source. As shown in FIG. 9A, the power source 902 may include a connector housing (or receptacle) 904 with a slot 908 configured to receive one end of the smart card 104 and contacts 906 (or terminals or electrodes, for example flexible conductive pins) within the housing. which are connected to the power element (eg battery 905) according to some modalities. In some embodiments, housing 904 is made of injection molded plastic and comprises a minimal number of parts. In some embodiments, housing 904 can be made of a transparent material so that the user can confirm that power source 902 is used solely for the purpose of providing power to smart card 104. The power source 902 is configured to be removably attached to a smart card by inserting the card into the slot 908, and the contacts 906 within the housing can make contact with the power transmitting contacts of the contact plates 108 (e.g. typically the C1 VCC and C5 GND contacts of the contact plates 108 of an EMVCo® compliant card of FIG. 1) to thereby electrically connect smart card 104 to the power element and provide power to card 104 when inserted into the power source housing 902. In an exemplary embodiment, eight contacts 906 are shown in FIGS. 9A through 9C corresponding to an exemplary pinout as shown on contact plates 108 of FIG. 1, but only two contacts 906 are needed to connect card 104 to the power transmitting contacts when the card is inserted into the power source housing 902. The remaining contacts can be omitted if no data is to be transmitted year of the card. Removing the card from the housing disconnects the card from the power source. In some embodiments, card 104 can only receive power from external power source 902 and does not require any additional external electrical connections or wireless connections to operate.

FIGS. 9D and 9E show a perspective view and plan view, respectively, of an alternative card holder / power source 910 (also referred to as a non-data transmitting power source) according to some embodiments. FIG. 9E illustrates exemplary, non-limiting dimensions of fastener 910 in millimeters. Fastener 910 comprises a slotted housing 912 (also referred to as a receptacle) configured to receive one end of card 104 (the outline of which is shown in phantom in FIG. 9D), a battery container 914 attached to housing 912 and configured to contain a suitable battery, 920 connecting pins attached to the battery contained in the battery container

914 and connecting the battery contained in the battery container 914 to the power transmission contacts of the card 104 contained in the housing 912. A retention arm 916 extends from the housing 912 and includes parallel arms with a lip 918 spanning the ends. of the two arms at a distal and thereof to mate with an edge of card 104, thereby holding card 104 in an inserted position relative to housing 912.

In some embodiments, the power source may comprise one or more LEDs or other status indicators (e.g. visual, audible, tactile indicators) used to indicate status to the user during enrollment in a situation where there are no status indicators on the smart card itself, or where the status indicators on the smart card are not suitable, in such embodiments, a component on the smart card 104, such as the fingerprint sensor, the secure element module or other processing circuitry that monitors the status of the enrollment process and modulates a power line on the card 104 in a known manner, depending on the status of the enrollment process. The power source may further comprise a sensing circuit configured to detect power line modulation and activate the one or more LEDs accordingly to indicate the correct status of the enrollment process.

The power source designs illustrated in FIGS. 9A to 9E are ideal for providing power to a smart card, however the same design principles can be applied to create power sources for other devices with limited feedback that contain fingerprint sensors. For example, a power source for an exercise monitor could provide power to the fingerprint sensor on the exercise monitor but might not need a data connection to the exercise monitor or fingerprint sensor.

Of course, if the device in which the fingerprint sensor is installed is an electronic device that has internal power, it may not be necessary to connect the device to an external power source to operate the fingerprint sensor. For example, the device may comprise an internal power source such as a solar cell panel or a battery.

There are multiple ways that the enrollment mode could be driven on the card using power supplied by a power source, such as power source 902. For example, the enrollment mode could be triggered automatically after detecting power to the card for the first time. In some embodiments, the enrollment mode could be actuated after an activation code has been successfully entered using a data entry device, such as the overlay tag as shown in FIGS. 3A and 3B. In some embodiments, the enrollment mode could be actuated by activating an input mechanism, such as a switch or switch arrangement located at the input source.

ΊΛ / t / ZUZU / UUU / JO energy. In either case, care must be taken to ensure that the smart card is not inadvertently removed from or otherwise disconnected from the external power source during enrollment mode. Thus, for an adhesively held overlay label as shown in FIG. 3B and a card inserted into a slot in a power supply housing, the label must be carefully removed from the card in such a way that the card is not removed from the housing. The following embodiments encompass power source arrangements that are intended to reduce the likelihood that the card will be disconnected from the power source when the coating on the data entry device is removed from the fingerprint sensor.

FIGS. 9Fa to 9H illustrate an alternative power source / card holder 920 according to some embodiments. FIG. 9F is a plan view without a card inserted into the card holder / power source (also referred to as a non-data transmitting power source) 920, and FIG. 9G is a cross-sectional view but showing a card inserted into the card holder / power supply. In some embodiments, fastener 920 comprises a substrate 922, for example a single-sided PCB, film, plastic, or cardboard. Card guide rails 924 may be mounted on substrate 922 and configured to receive one end of card 104. In some embodiments, a battery container 926 may be connected to substrate 922 and configured to contain a suitable battery 928. The connecting pins 930 attached to the substrate between the card guide rails 924 are conductively coupled to the battery 928 via conductive cues on or within the substrate and connect the battery to power transmission contacts 923 of the card 104 contained in the rails card guide rail 924. Card guide rails 924 may fit around one or more edges of card 104 to hold it in position. The card guide rails 924 can be attached directly to the substrate, or held in place with mounting bolts 932 that fit into corresponding holes in the substrate. In some embodiments, status indicators 921, such as LEDs, may be added to substrate 922. In an alternative embodiment illustrated in cross-section in FIG. 9H, the card guide rails 924 may be replaced with a housing 934 configured to receive one end of the card 104 and hold it in place. Housing 934 can be attached directly to the substrate, or held in place with mounting bolts 932 that fit into corresponding holes in substrate 922.

FIGS. 10A to 10E illustrate an alternative power source with a connector 1002 in use with the fingerprint sensor 102 installed on the smart card 104 according to some embodiments. As shown in FIG 10A, the power source (also referred to as a non-data transmitting power source) 1002 comprises an upper cover 1004, a lower cover 1006, and a fin 1010 connected to the lower cover 1006 with a connection. of

ΊΛ / t / ZUZU / UUU / JO hinge or folding 1008. Top cover 1004 combines with bottom cover 1006 to form a pocket in which smart card 104 can be removably received. The bottom cover 1006 is longer than the top cover 1004 by approximately the width of the flap 1010. This allows the flap 1010 to flip over to close onto the bottom cover 1006 to form an upper cover extended over the entire area of the bottom cover 1006 . Fin 1010 comprises drilled holes 1014A-E positioned in an upper corner adjacent to hinge 1008. The function of drilled holes 1014A-E will be described in more detail in FIG. 10D. The upper and lower covers 1004, 1006 form a housing that receives the card. The power source may include a portable power element (for example a battery or solar element, not shown), and contact elements (not shown) internal to the housing provide electrical contact to the power transmission contacts of the card when the card is inserted into the housing.

As shown in FIG. 10A, smart card 104 comprises an LED 1012, contact pads 108 that can be part of a secure element module that conforms to the EMVCo® protocol, and a fingerprint sensor 102 that comprises a detection area 106. In some In embodiments, the fingerprint sensor 102 is positioned in one of the uppermost corners of the smart card 104.

As shown in FIG. 10A, the flap 1010 of the power source (also referred to as a non-data transmitting power source) 1002 is open and the smart card 104 is positioned so that the smart card 104 can be inserted into the power source 1002 at direction B. As shown in FIG. 10B, the smart card 104 is inserted into the pocket formed by the upper and lower covers 1004, 1006 of the power source 1002. Consequently, the power source 1002 is removably connected to a power input, such as the power transmission contacts of the contact plates 108, on the smart card 104 and provides power to operate the fingerprint sensor 102.

As shown in FIG. 10C, once the smart card 104 is fully inserted, the top cover 1004 of the power source 1002 partially covers the surface of the smart card 104, exposing the fingerprint sensor 102. The flap 1010 is then flipped over to close. the uncovered portion of the smart card 104. In some embodiments, the drilled holes 1014A-E are located in the flap 1010 so that when the flap 1010 is closed, the punched holes 1010A-E expose portions of the sensing area 106 and LED 1012 to provide an input device for data to enable a user to enter a code via sensor 102. In some embodiment, the number, size, and position of the drilled holes 1010A-D can be configured as described in FIGS. 4A to 6C.

As shown in FIG. 10D, 1014A-D drilled holes are numbered

In some embodiments, the user can enter data, such as a numerical activation code by placing a finger 1015 over the drilled holes numbered 1014A-D in a specific sequence. The 1014E drilled hole on the 1012 LED allows the user to receive status indications while entering data.

In other embodiments, flap 1010 may comprise built-in mechanical buttons instead of drilled holes 1014A-D. In such embodiments, when the flap 1010 is closed, the built-in mechanical buttons make contact with the detection area 106 when depressed by a user. In some embodiments, the plates on the built-in mechanical buttons are conductive so that contact with the detection area 106 can be detected by the sensor. In some embodiments, the built-in mechanical buttons can be dome, plunger, and vial buttons to provide a tactile aspect of the data entry keys.

As shown in FIG. 10E, once the user completes data entry (eg, enters a correct code), flap 1010 can be opened and smart card 104 can be removed. In some embodiments, the fingerprint sensor can begin a fingerprint enrollment process once the user makes a correct code or data entry. In some embodiments, the flap 1010 is opened and the entire detection area 106 is revealed to proceed with the fingerprint enrollment process. A detectable feature - such a mark or pattern of a conductive ink - may be provided on the back side of the flap 1010 to allow the sensor 102 to detect whether the flap 1010 is open or closed and / or allow the sensor to calibrate the exact position of the flaps. orifices as described above in relation to FIG. 8. Smart card 104 can be removed from power source 1002 at address C after a sufficient fingerprint template of the user's fingerprint is acquired and stored.

In some embodiments, power source 1002 can be used for purposes other than recording as described in FIGS. 10A to 10E. For example, power source 1002 can be used to block, or temporarily disable, smart card 104. To block smart card 104, smart card 104 can be inserted into power source 1002 as illustrated in FIGS. . 10A and 10B. Once the smart card 104 receives power from the power source 1002, the user can place a finger in the detection area 106 for verified use of the smart card 104. Subsequently, the user can flip the flap 1010 over the uncovered portion of the smart card 104 such that the punched holes 1010A-E expose the portions of the detection area 106 and the LED 1012 to provide a data input device to enable the user to enter a code via the

ΊΛ / t / ZUZU / UUUZ sensor 102, as described in FIGS. 10C to 10D. In such embodiments, the user can retrieve a numeric lock code for smart card 104. For example, the user can retrieve the numeric lock code through a phone call, an SMS, or an online banking application. Once the user retrieves the numeric lock code, the user can enter the lock code by placing a finger over the punched holes numbered 1014A-D in a sequence according to the code. As a result of a valid lock code entry, the smart card may be temporarily blocked or disabled from use. Smart card 104 can be removed from power source 1002 after the lockout process is complete. In some embodiments, the above-described process for locking smart card 104 can be used to unlock smart card 104. In another embodiment, smart card 104 can be unlocked by placing a finger on detection area 106 for verification.

As shown in FIG. HA, smart card 104 may already be removably received at power source 1102, which may comprise a wrap-type housing configured to receive one end of the card and provide electrical contact between a power element (for example, a battery or cell). solar) and the card. The power source 1102 only partially covers the smart card 104 so that the portion containing the fingerprint sensor 102 is exposed. A continuous sleeve 1104 wraps around a lower end of combined power source 1102 and around the left, right, and lower ends of smart card 104 to hold smart card 104 in place within the power source housing. power 1102. A data input device in the form of a sleeve 1106 can be used to cover the portion of the smart card 104 that contains the fingerprint sensor 102. In some embodiments, sleeve 1106 overlaps one end of continuous sleeve 1104. Perforated holes 1108A-E located in sleeve 1106 expose portions of detection area 106 and an LED 1110 on fingerprint sensor 102. In one embodiment , a battery connection tab 1112 may be provided between power source 1102 and smart card 104 to keep a power connection disconnected until ready for use. The user can pull the battery connection tab 1112 out in direction D, as shown in FIG. 11A, to connect power source 1102 to smart card 104 to operate fingerprint sensor 102.

In some embodiments, the drilled holes 1108A-D may be numbered and indicate spatially different control areas on the fingerprint sensor 102 as shown.

Consequently, once the user connects the smart card 104 to the power source 1102, the user can enter data, such as a numerical activation code, by placing a finger over the punched holes 1108A-D in a specific sequence. The 1108E drilled hole above the 1110 LED allows the user to receive status indications while entering data. Once the user has successfully entered the data and the fingerprint sensor is ready to initiate enrollment mode, the sleeve 1106 can be slid out of the smart card 104 in direction E, as shown in FIG. HA, while continuous sleeve 1104 remains intact to keep card 104 inserted in power source 1102.

As shown in FIG. 11B, slipping away sleeve 1106 reveals a corner of smart card 104 that contains fingerprint sensor 102. In some embodiments, a detectable feature - such as a conductive ink mark or pattern - may be provided on an interior surface. of sleeve 1106 to allow sensor 102 to detect if sleeve 1106 is in position. After the start of the enrollment mode, the user can place a finger in the detection area 106. After a sufficient fingerprint template of the user's fingerprint has been acquired and stored by the fingerprint sensor 102, the continuous sleeve 1104 can be slidably removed in direction F, as shown in FIG. 11B. After continuous sleeve 1104 is slid out, smart card 104 can be removed from power source 1002 in direction E, as shown in FIG. 11C.

FIGS. 12A through 12C illustrate another embodiment of a power source (also referred to as a non-data transmitting power source) 1202 in use with the fingerprint sensor 102 installed on the smart card 104. As shown in FIG. 12A, smart card 104 may already be removably received at power source 1202, which may comprise a wrap-around housing configured to receive one end of the card and provide electrical contact between a power element (eg, a battery or power element). solar) and the card. The power source 1202 only partially covers the smart card 104 so that the portion containing the fingerprint sensor 102 is exposed. A data entry device in the form of a sleeve 1204 is used to cover the portion of the smart card 104 that contains the fingerprint sensor 102. One side of the sleeve 1204 comprises perforated holes 1206A-E that expose portions of the fingerprint area. detection 106 and an LED 1208 on the fingerprint sensor 102. A detectable feature - such as a conductive ink mark or pattern - may be provided on an interior surface of sleeve 1204 to allow sensor 102 to detect if sleeve 1204 is in place. In some embodiments, a battery connection tab 1210 is inserted between the power source 1202 and the smart card 104 to maintain

ΊΛ / t / ZUZU / UUUr JO disconnected a connection power. The user can pull out the battery connection tab 1210 in direction D, as shown in FIG. 12A, to connect power source 1102 to smart card 104 to operate fingerprint sensor 102.

In some embodiments, the drilled holes 1206A-D may be numbered and indicate spatially distinct control areas on the fingerprint sensor 102 as shown in FIG. 12A. In such embodiments, once the user connects the smart card 104 to the power source 1202 by inserting the card into the power source housing 1202 or by removing the tab 1210 from the power source 1202 on which the card already inserted, the user can enter data, such as a numeric activation code, by placing a finger over the pre-drilled holes 1206A-D in a specific sequence. The 1206E drilled hole above the 1110 LED allows the user to receive status indications while entering data. Once the data has been correctly entered by the user, sleeve 1204 can be removed by sliding smart card 104 in direction E, as shown in FIG. 12A.

In some embodiments, once sleeve 1204 has been slipped away, a user can flip sleeve 1204 upside down to reveal finger guide 1212 and slide sleeve 1204 back over smart card 104 in direction B, such as shown in FIG. 12B. Finger guide 1212 may be a cutout window that indicates to the user where to place a finger on the sensor during enrollment mode. The sleeve 1204 can then be removed from the smart card 104 after a sufficient fingerprint template of the user's fingerprint has been acquired and stored by the fingerprint sensor, and the smart card 104 is then removed from the source. of energy 1202 in direction E, as shown in FIG. 12C.

FIG. 13 illustrates an application of another embodiment of a data entry device in the form of an overlay 1302 placed over the detection area 106 of the fingerprint sensor installed on the smart card 104. In the illustrated embodiment shown in FIG. 13, a smart card is the device that contains the fingerprint sensor, but the application of the data input device is not restricted to a smart card and can be used for any device that contains a fingerprint sensor in alternative modes. As shown in FIG. 13, the overlay 1302 is removably positioned over a portion of the card 104 including the detection area 106 (as shown by the dotted lines in FIG. 13). In some embodiments, the overlay 1302 may comprise data entry keys 1304A-D associated with (eg, coupled to) spatially different detection areas in the detection area 106 of the fingerprint sensor. The data entry keys 1304A-D are located remotely from the detection area 106. In some embodiments, the overlay 1302 may comprise one or more additional drilled holes to indicate the control areas.

ΊΛ / t / ZUZU / UUU / JO spatially different from detection area 106, as shown in FIG. 13, plus data entry keys 1304A-D located remotely from detection area 106. As shown in FIG. 13, the portions of the detection area associated with the data entry keys 1304A-D do not overlap with the spatially different control areas of the detection area indicated by one or more additional drilled holes. In some embodiments, the overlay 1302 may comprise a punched hole 1306 on the LED 308 or other indicator element on the card 104 when the overlay 1302 is temporarily placed on a portion of the card 104 including the detection area 106 and the LED 308. In some embodiments, an OLED display can operate as the fingerprint sensor. In such embodiments, a portion of the OLED display can be configured to be used as the indicator element. Consequently, the drilled hole 1306 can be positioned on the portion of the OLED display configured to be used as the indicator element.

When the fingerprint sensor is used in data entry mode, each 1304A-D data entry key can function to enable the user to enter numbers (for example an activation code, such as a PIN code) by tapping their finger in spatially distinct control areas 1304A-D. Each data entry key 1304A-D of overlay 1302 is electrically coupled to a spatially distinct associated portion of the sensing area 106 so that contact with each key will result in a detectable signal from the sensor element (s) of the spatially distinct associated portion of sensing area 106. Coupling between keys 1304A-D and sensing area 106 allows keys 1304A-D to be remotely located from sensing area 106. This provides the significant advantage of positioning keys 1304A-D in locations not restricted by the limits of detection area 106. For example, additional space on smart card 104 can be used to provide additional keys (eg more than four keys) or keys 1304A-D may be separated, which can improve user access. In some embodiments, the overlay 1302 may comprise a data entry key electrically coupled to a spatially distinct associated portion of the sensing area 106 configured to receive Morse code type data input by the user.

As shown in FIG. 13, the data entry keys 1304A-D can be spread on the overlay 1302 along a short edge of the smart card 104. In some embodiments, the data entry keys 1304A-D can be spread over the overlay. 1302 along a long edge of smart card 104. In other embodiments, the data entry keys 1304A-D may be distributed on the overlay 1302 in the middle of the smart card 104, rather than being restricted to the short or long edge. The data entry keys 1304A-D can be arranged in various suitable formats depending on the

ΊΛ / t / ZUZU / UUU / JO application. For example, the data entry keys 1304A-D may be arranged in a 2-D matrix format, a keyboard format, or a calculator bearing format.

Power must be applied to card 104 through an entire data entry and enrollment process. In an exemplary non-limiting embodiment, a battery powered power source, as shown in FIG. 9A, can be configured to be removably attached via contact plates 108 to the external battery powered power source. A small tab 1310 extending from one side or corner of the liner 1302 may be provided to facilitate holding the liner 1302 so that the user can remove the liner 1302 with ease. Care must be taken, however, to ensure that the card is not inadvertently disconnected from the power source in the process of removing the coating 1302 from the card 104. In some embodiments, the small tab 1310 is at an edge or corner of the liner 1302 which encourages the user to remove the liner 1302 in a direction that moves toward the power source, rather than pulling away from the power source. , to avoid separating the card from the power source.

In some embodiments, the card 104 may include an LED 308 or other indicator element, and the overlay 1302 may comprise a drilled hole 1306 positioned over the LED 308 that allows the user to view the LED when the overlay 1302 is temporarily placed over a portion of card 104 including detection area 106 and LED 308. In other embodiments, card 104 may include more than one LED 308 or other indicator element. LED 308 can light and blink to communicate various instructions and confirmations to the user.

In some embodiments, the cover 1302 may be provided as a sleeve configured to be slid over the portion of the smart card 104 that contains the detection area 106, as shown in FIGS. HA and 12A. The data entry keys can be located anywhere on a cuff surface. Each data entry key may be electrically coupled to a spatially distinct associated data entry portion of the sensing area 106 so that contact with each key will result in a detectable signal from the sensing element (s) of the associated data entry portion. data spatially distinct from the detection area 106.

In some embodiments, coating 1302 can be provided as an alternative power source (also referred to as a non-data transmitting power source), as shown in FIG 10A. In such modes, the data entry keys can be located on the fin of the power source. The flap may comprise conductive indicia that electrically couple each data entry key to an associated input portion spatially distinct from the detection area 106.

FIGS. 14A to 14C illustrate one embodiment of a data input device

ΊΛ / t / ZUZU / UUU / JO in the form of a 1402 overlay that includes data entry keys coupled to spatially distinct detection areas in the fingerprint sensor detection area, where the data entry keys are located remotely from the detection area. As shown in FIGS. 14A through 14C, coating 1402 is a double layer coating comprising a top layer 1404 and a bottom layer 1406. The bottom of the lower layer 1406 contacts the surface of the detection area 106 when the coating 1402 is positioned over the detection area 106. In some embodiments, the upper layer 1404 and the lower layer 1406 can be made of film that can be remove.

As shown in FIG. 14B, top layer 1404 may comprise punched holes 1408A-D defining the data entry keys, a punched hole 1410 for an LED 308 or other indicating element on smart card 104, and a tab 1412 for easy removal of the coating 1402 . In some embodiments, the edge surface surrounding each drilled hole 1408A-D defining the data entry keys may be slightly raised so that a user can feel the circumference of the holes when placing a finger on it.

As shown in FIG. 14C, the bottom layer 1406 may comprise key indicia 1414A-D, connect indicia 1416A-D, detection area activation indicia 1418A-D, and a punched hole 1410 for an LED 308 or other indicator element on the smart card. 104. In some embodiments, a conductive material, such as conductive ink, metallization, conductive polymer, or any conductive coating can be used to print or apply key indicia 1414A-D, connect indicia 1416A-D, and activation indicia. detection area 1418A-D on a surface of bottom layer 1406. Key indicia 1414A-D can be located remotely from sensing area activation indicia 1418A-D. Connection indicia 1416A-D may connect key indicia 1414A-D to each respective associated detection area activation indicia 1418A-D. The detection area activation indicia 1418A-D are located in the lower layer 1406 so that the detection area activation indicia 1418A-D align with the associated spatially distinct data input regions of the detection area 106 when coating 1402 is temporarily placed over smart card 104. In some embodiments, the material of bottom layer 1406 is thin polymer, typically no more than 50-100 microns in thickness. The material and thickness of the lower layer 1406 should be such that it does not negatively impact the electrical coupling of the detection area activation indicia 1418A-D with the associated spatially distinct data input regions of the detection area 106. In some embodiments, the reference indicia may be printed or applied or otherwise incorporated between each detection area activation indicia 1418A-D on the surface of the bottom layer 1406 so that the indicia

ΊΛ / t / ZUZU / UUU / JO reference indicia are aligned with spatially distinct associated reference regions of detection area 106. The alignment of detection area activation indicia 1418A-D relative to detection area 106 is described in greater detail in FIGS. 15A and 15B and FIGS. 19A to 19D.

FIG. 14A illustrates a surface of the double-sided coating 1402 when the upper layer 1404 is combined with the lower layer 1406 according to some embodiments. When combined, the data entry keys are defined by the key indicia 1414A-D visible and accessible through the drilled holes 1408A-D. Connection indicia 1416A-D and detection area activation indicia 1418A-D are covered by top layer 1404 and are hidden from view. In addition, the top layer 1404 may be formed of an electrically insulating material to isolate the connection indicia 1416A-D and the detection area activation indicia 1418A-D.

FIG. 15A illustrates the data entry device in the form of a double layer coating 1402 (top layer 1404 not shown) temporarily placed on the smart card 104 in accordance with some embodiments. As shown in FIG. 15A, the double layer coating 1402 covers a portion of the smart card 104 that contains the detection area 106. Overlay 1402 is placed on smart card 104 so that detection area activation indicia 1418A-D in bottom layer 1406 are covering and aligned with spatially discrete regions of detection area 106 (encompassing one or more elements specified sensors) associated with each 1414A-D key.

In some embodiments, the detection area 106 may be a sensor grid comprising spatially spaced rows and columns of drive lines and pickup lines that form an array of sensor elements at overlapping locations of drive lines and pickup lines. The fingerprint sensor may be pre-programmed with the expected positions of the detection area activation indicia 1418A-D corresponding to specific sensor elements in the detection area 106. For example, the fingerprint sensor may be pre-programmed to expect detection area activation indicia 1418A-D to cover certain rows (or portions thereof) and columns (or portions thereof) of the detection area 106. and the associated sensor elements of the rows and columns. For example, when a finger makes contact with a key cue 1414A, marked 1, the respective detection area activation cue 1418A is grounded through the connect cue 1416A, thereby changing the signal detected on the lines. pickup devices (or portions thereof) (ie, the sensor elements) covered by the detection area activation indicia 1418A. Based on the location of the detected portion of the detection area 106, the fingerprint sensor is able to determine which key hint 1414A-D has been contacted by the finger and conclude the associated data entry, which is 1 in this stage.

Each of the detection area activation indicia 1418A-D can be positioned to cover a portion of the detection area 106. As shown in FIG. 15A, detection area 106 comprises a grid of overlapping drive lines and pickup lines as described above and each of the detection area trigger indicia 1418A-D may have an elongated configuration oriented substantially in the same direction as the catchment lines. Each of the detection area activation indicia 1418A-D may overlap a substantial portion of at least one capture line. In some embodiments, each of the detection area activation indicia 1418A-D may overlap the entire at least one pickup line. In some embodiments, each of the detection area activation indicia 1418A-D may overlap a substantial portion of at least four or more pickup lines. In some embodiments, each of the detection area activation indicia 1418A-D may overlap all of the at least four or more capture lines. In some embodiments, the detection area activation indicia 1418A-D are transverse with the pickup lines of the detection area 106.

In some cases, the double-layer coating 1402 may be misaligned with the detection area 106. Consequently, the detection area activation indicia 1418A-D may be placed on the detection area 106 misaligned with the previously programmed expected positions. on the fingerprint sensor. In some embodiments, the dual-layer coating 1402 may comprise detectable features and the location of such features as detected by the fingerprint sensor may indicate the position of the coating 1402 relative to the detection area 106. A calibration method for the The fingerprint sensor based on the detectable features provided in the double layer coating 1402 is described in more detail in FIG. 8. Consequently, the fingerprint sensor can detect a margin of misalignment between the 1418A-D detection area trigger indicia and the expected positions in the detection area, and factor the margin of misalignment in the processing of inputs. received through each detection area activation indicia 1418A-D.

In some embodiments, the detectable features provided in the dual layer coating 1402 with respect to the detection area 106 may comprise conductive lines that form a unique pattern of dots, dashed lines, and gaps. The unique pattern can be detected, similar to a barcode pattern, and correlated with a specific instruction or other information. For example, the pattern could authenticate overlay 1402 to confirm that the correct overlay is placed on the card. In a situation where different coatings can be used for different data entry functions, the unique detectable code may correspond to the particular functionality to thereby cause the fingerprint sensor to

ΊΛ / t / ZUZU / UUU / JO digital is set to the correct data input mode.

In some embodiments, the detectable features provided on the dual-layer coating 1402 with respect to the detection area 106 allow the fingerprint sensor to detect whether the coating 1402 has been removed. In such modes, the fingerprint sensor can be configured not to enter an enrollment mode until coating 1402 has been removed, in some modes, a variety of different coatings - each corresponding to a different data entry functionality. - can be temporarily placed over the detection area 106 to operate the fingerprint sensor. Each coating can have a dedicated conductive ink pattern that the fingerprint sensor can recognize. In some embodiments, certain coatings may be restricted in use relative to the fingerprint sensor. In such embodiments, the fingerprint sensor can recognize a restricted coating based on the dedicated conductive ink pattern and deny access for that particular coating.

In some embodiments, the detection area 106 comprises a linear array of sensor elements, as shown in FIG. 15B. Exemplary embodiments of sensor element arrays are described in US Patent No. US 7,110,577, entitled Method and Apparatus for Measuring Structures in a Fingerprint and US Patent No. 7,751,601, entitled Fingerprint Detection Assemblies and Manufacturing Methods, the respective descriptions of which are incorporated by reference in their entirety. As shown in FIG. 15B, the overlay 1402 is placed on the smart card 104 so that the detection area activation indicia 1418A-D in the bottom layer 1406 are covering spatially discrete portions of the detection area 106 (encompassing one or more specified sensor elements of the line array) associated with each 1414A-D key.

FIG. 15C illustrates an enlarged view of the detection area activation indicia 1418A-D positioned over the detection area 106 in accordance with some embodiments. As shown in FIGS. 15A and 15C, reference indicia 1502A-C may be printed or otherwise applied on or incorporated into a surface of the lower layer 1406 between each of the detection area activation indicia 1418A-D so that the indicia reference 1502A-C align with spatially distinct associated reference regions of the detection area 106. Detection area activation indicia 1418A-D are connected via connection indicia 1416A-D to key indicia 1414A-D. Reference indicia 1502A-C are not connected to key indicia 1414A-D and can be used to employ a differential signal detection structure for fingerprint sensor 102. As shown in FIG. 15D, the sensing elements covered by a detection area trigger hint 1418A are connected to a positive input 1503A of a differential amplifier 1504 located in the sensor

Fingerprint ΊΛ / t / ZUZU / UUUZ, and the sensor elements covered by an adjacent reference indicia 1502A are connected to a negative input 1503B of the differential amplifier 1504 according to some embodiments. Reference indicia 1502A may be subjected to unwanted signal and noise inputs similar to those of detection area activation indicia 1418A. In some embodiments, when a finger makes contact with a key cue 1414A, the contact by the finger completes the circuit connection key cue 1414A to ground 1506, thereby changing the pickup signals detected in the sensor elements covered by the activation cue 1418A. In such embodiments, the differential amplifier 1504 may be configured to subtract the pickup signals from the sensing elements covered by the reference indicia 1502A from the pickup signals from the sensing elements covered by the trigger indicia 1418A, thereby eliminating the noise and unwanted signal inputs that affect both pickup signals equally, and leaving only substantially the signal variation in the sensor elements covered by the activation indicia 1418A due to contact with the key indicia 1414A. Thus, the sensor removes noise by subtracting the pickup signals from the sensor elements covered by a reference cue signal 1502A from the pickup signals from the sensor elements covered by an activation cue 1418A-D in the differential amplifier 1504. The use of reference cues 1502A-C to eliminate noise allows a better detection rate for the keys. In some embodiments, a reference indicia 1502A can be used to eliminate noise for all detection area activation indicia 1418A-D.

FIGS. 15E to 15H illustrate modes of arrangement of conductive material in the data input device in the form of a coating when temporarily placed over the detection area of the fingerprint sensor. As shown in FIG. 15A, the conductive material comprises four detection area activation indicia 1418A-D connected to four key indicia 1414A-D (not shown in FIG. 15E) via connection indicia 1416A-D and three reference indicia 1502A-C. In some embodiments, the four activation indicia 1418A-D provide a 4-key data entry device. As shown in FIG. 15E, each reference indicia 1502A-C is positioned between a two detection area activation indicia 1418A-D. The indicia placed on the detection area 106 are separated by a predetermined space 1504. In some embodiments, the width of the detection area activation indicia 1418A-D, the reference indicia 1502A-C, and the space 1504 can be determined based on the choice of conductive material used to print or insert the indicia in the coating and in the detection area 106. For example, an achievable printer resolution may govern the minimum value of the indicia width and gap 1504 if conductive ink is used as the conductive material.

In some embodiments, a single 1502A-C datum can be used to

ΊΛ / t / ZUZU / UUU / JO two or more detection area activation indicia 1418A-D provided that the sensing elements associated with the two or more detection area activation indicia 1418A-D will not be detected simultaneously when they share the single reference token 1502A-C. For example, a first detection area trigger cue 1418A may use a reference cue 1502A and a second detection area trigger cue 1418B may also use reference cue 1502A for detection of the differential signal. In such embodiments, the sensor elements associated with the first detection area activation indicia 1418A and the second detection area activation indicia 1418B should not be simultaneously detected when they share the single reference indicia 1502A. In some embodiment, the second detection area activation indicia 1418B may use a second reference indicia 1502B.

FIG. 15F illustrates another way to arrange conductive material over the fingerprint sensor detection area. As shown in FIG. 15F, the reference indicia are not used and only the detection area activation indicia 1418A-D are placed over the detection area 106 of the fingerprint sensor 102. Each of the detection area activation indicia 1418A- D are separated by a predetermined space 1504. In some embodiments, the detection area activation indicia 1418A-D are evenly distributed over the detection area 106. In other embodiments, the detection area activation indicia 1418AB are not evenly distributed over the detection area 106 and are concentrated in a specific portion of the detection area 106, as shown in FIG. 15G. In some embodiments, detection area activation indicia 1418A-B can have any size or profile, as shown in FIG. 15H. As shown in FIG. 15H, detection area activation indicia 1418A-B are not restricted to the profile of a strip having a length corresponding to the width of the detection area along the G direction. For example, detection area activation indicia 1418A-B may have the profile of square or rectangle blocks in the detection area. When the 1418A-B detection area trigger indicia are in the outline of a square block or rectangle, there may be a loss in detection sensitivity because the 1418A-B detection area trigger indicia are not aligned with the total length of the pickup lines of the detection area 106. To compensate for any loss in detection sensitivity, the 1418A-B square or rectangle block detection area trigger indicia are wider along the length of the detection area, that is, the H direction, to cover more catchment lines. In some embodiments, the area of a square or rectangle block detection area activation indicia 1418AB is the equivalent of an area of a detection area activation indicia in the outline of a strip as illustrated in FIG. . 15G. Consequently, a square or rectangle block detection area activation indicia 1418A-B may cover the same area of the detection area 106 as a detection area activation indicia 1418A-B in the profile of a strip and therefore thus covering the same number of pickup / driver line overlays (ie, sensor elements) as the strip profile trigger cue.

FIG. 16A illustrates an embodiment of an alternative noise reduction concept in which the data input device comprises one or more keys 1614 formed as interdigitated sheets 1608A-B. In some embodiments, each of the one or more keys 1614 comprises a first sheet 1608A and a second sheet 1608B. As shown in FIG. 16A, the first sheet 1608A is connected to a first detection area drive marker 1610A and the second sheet 1608B is connected to a second detection area drive sign 1610B. Consequently, each key 1614 can be associated with sensor elements covered by two sensor activation indicia 1610A, 1610B. The sensor elements covered by the first detection area activation indicia 1610A can be connected to a negative input 1611B of the differential amplifier 1604 and the sensor elements covered by the second detection area activation indicia 1610B can be connected to a positive input. 161 IA of differential amplifier 1604. In some embodiments, drivers 1609A-B can drive positive input 1611A 180 degrees out of phase with negative input 1611B of differential amplifier 1604. In some embodiments, when a finger contacts key 1614 and simultaneously contacts first and second blades 1608A and 1608B, contact by the finger completes the circuit by connecting key 1614 to ground 1606A-B, thereby changing the pickup signals detected in the sensor elements associated with the trigger indicia 1610A-B. In such embodiments, the differential amplifier 1604 subtracts the pickup signals from the sensing elements associated with the first detection area pickup cue 1610A from the pickup signals from the sensor elements associated with the second pickup cue 1610B, thus eliminating noise and unwanted signal inputs that equally affect the pickup signals, and acquiring a difference signal that could be easily detected by the fingerprint sensor.

FIG. 16B illustrates an embodiment of an alternative noise reduction concept in which the data input device comprises one or more keys 1624 formed as split sheets 1618A-B. In some embodiments, each of the one or more keys 1624 comprises a first sheet 1618A and a second sheet 1618B. As shown in FIG. 16B, the first sheet 1618A is connected to a first detection area activation indicator 1620A and the second sheet 1618B is connected to a second detection area activation indicator 1620B. Consequently, each key 1624 is associated with sensor elements covered by two sensor activation indicia 1620A, 1620B. The sensing elements covered by the

ΊΛ / t / ZUZU / UUUZ first detection area trigger indication 1620A are connected to a negative input 1621B of a differential amplifier 1616 and the sensing elements covered by the second detection area trigger indicator 1620B are connected to a positive input 1621A of differential amplifier 1616. In some embodiments, drivers 1619A-B drive positive input 1621A 180 degrees out of phase with negative input 1621B of differential amplifier 1604. In some embodiments, when a finger contacts key 1624 and simultaneously contacts first and second blades 1618A and 1618B, contact by the finger completes the circuit by connecting key 1624 to ground 1606A-B, thereby changing the pickup signals detected in the sensor elements covered with trigger indicia 1620A-B. In such embodiments, the differential amplifier 1616 subtracts the pickup signals from the sensing elements covered with the first detection area drive indicia 1620A from the pickup signals from the sensor elements covered with the second pickup indicia 1620B, thus eliminating noise and unwanted signal inputs that equally affect the pickup signals and acquiring a differential signal that could be easily detected by the fingerprint sensor.

FIG. 22 is a flow chart illustrating one embodiment of a simple method,

ΊΛ / t / ZUZU / UUU / JO cost effective 2200 to enroll a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a smart card, is described in detail then. In the illustrated embodiment shown in FIG. 22, a smart card is assumed to be the device that contains the fingerprint sensor, but the method is not restricted to a smart card and can be used for any device that contains a fingerprint sensor in alternative modes. A smart card, as defined by the Smart Card Alliance, is a device in which an integrated circuit, or chip, is incorporated. Smart card technology conforms to ISO / IEC 7816 and ISO / IEC 14443 international standards. Consequently, a person of ordinary skill in the art will understand that a smart card is not restricted to a plastic card. Although the plastic card was the initial form factor of the smart card, the technology used for the smart card is now available in a wide variety of form factors, including plastic cards, radio keys, and subscriber identification modules. (SIMs) used in GSM mobile phones, watches, electronic passports and USB-based tokens. Smart card applications include, and are not restricted to, bank cards, mobile phone subscriber identification (SIM) modules, health services cards, government and business ID cards, benefits and welfare cards, driver's licenses, physical or logical access cards, mass transit cards (ticketing), and card that combines multiple applications on a single card,

At step 2202, a data entry device, such as the data entry device in the form of an overlay as shown in FIGS. 3B and 13 or the data input device in the form of a sleeve as shown in FIGS. 10A to 12C, temporarily connects to a fingerprint-enabled smart card. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the smart card and encrypted at a secure location during the smart card manufacturing process. The fingerprint sensor on the smart card is calibrated during the manufacturing process and is set to data entry mode before the smart card is sent to the user. A data entry device, such as, for example, any of the coatings or sleeves described herein, can be placed on the card as a final or near-final step in the card manufacturing process. In some embodiments, the data entry device can be temporarily placed over the portion of the card including the detection area 106 by applying a repositionable adhesive provided by companies such as 3M, Krylon, Franklin Adhesives, and Polymers and Bostik.

In step 2204, the card provider provides the smart card and a simple low-cost power source to the user, for example sent by mail or courier or

ΊΛ / t / ZUZU / UUUZ given by a bank or retail store. The power source could be battery powered, powered by mains (eg via a USB connector), or solar powered. An exemplary non-limiting embodiment of the power source is described in FIGS. 9A to 9H. In some embodiments, if the smart card contains an on-board power source, the power source need not be provided to the user.

In some embodiments, the smart card and power source can be delivered to the user with the smart card already inserted into the power source as described in FIGS. 11A to 11C and 12A to 12C. In such embodiments, a battery connection tab may be inserted between the power source and the smart card to keep a power connection disconnected. The user can pull out the battery connection tab, as shown in FIG. 12A, to connect the power supply to the smart card.

In step 2206, the user follows the instructions, received with the card, to obtain an activation code from the card provider. For example, the user may be prompted to call a number, or the data entry device may have a QR® code that the user can scan with a smartphone, or the user may enter your online banking site or application. mobile and indicate that you want to receive an activation code by SMS. In some modes, other secure mechanisms are available to obtain the activation code. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 2208, if not already done, the user connects the smart card to the power source, for example by inserting the card into a power source housing. The card receives power from the power source, and a status indicator on the smart card (for example an LED) indicates to the user that the smart card is ready.

At step 2210, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code, for example, as described in FIGS. 2A, 3A and 3B, 10D, 11A, 12A, 13, 17, 18, 19 and 20. The fingerprint sensor can be configured to simply detect the presence of the finger on the direct or remote contact data entry key in code entry and unlock mode. In some modes, the fingerprint sensor can be configured to detect peaks and valleys of the fingerprint in unlock code entry mode.

In some embodiments, the fingerprint sensor may comprise a status indicator configured to indicate to the user that the entered code is correct or incorrect. If the code entered is incorrect, the user can make a predetermined number of attempts

Additional ΊΛ / t / ZUZU / UUU / JO before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modes, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card blocks the user permanently.

In some embodiments, if one or two unsuccessful entries have been made, the number of unsuccessful entries is stored in non-volatile memory. In such modes, even if power to the smart card is removed and reapplied, the smart card will still remember how many unsuccessful entries have been made. Consequently, the card cannot be reset to a full complement of attempts by disconnecting the card after a number of unsuccessful attempts that is less than the maximum number of attempts allowed.

In some embodiments, a smart card state can be stored in the card's non-volatile memory. For example, the different states can include: (i) new state which means the card is awaiting unlocking by entering a valid activation code; (I) unlocked status which means the card is unlocked but enrollment has not been successfully completed; (iii) active status which means that the card is unlocked and an enrollment has been successfully completed; and (iv) locked state which means that the card unlocking procedure has been tried without success.

In step 2212, if the activation code has been entered correctly, the user can now remove the data entry device from the card and begin enrollment of a fingerprint (enrollment mode). The smart card must remain connected to the power source throughout the entire enrollment process. The status indicator gives an indication to the user when an image is acceptable, for example by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example by the LED flashing many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

ΊΛ / t / ZUZU / UUU / JO finger hold, to avoid draining the power source. For example, once the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

In step 2214, the user removes the smart card from the power source. In some embodiments, the power source can be scrapped.

Consequently, the user has now successfully enrolled a fingerprint on the smart card through the simple, cost-effective method 2200 and can use the smart card in the normal way to pay for items, but now requires fingerprint verification. to use the smart card. In some embodiments, multiple users can enroll a fingerprint on the smart card, or one user can enroll multiple fingers on the smart card, using the above 2200 method. In such embodiments, the card can be programmed with multiple activation codes that are provided to each user. For each 2200 method, a new activation code is required and entered to enroll a new user / finger.

In some embodiments of method 2200, the data entry device can be provided as a sleeve and guide the user to enter the activation code as described in FIGS. 11A to 11C and 12A to 12C.

In some embodiments of the 2200 method, the overlay may not be required to guide the user to enter the activation code, in such embodiments the power source may comprise a perforated fin or guide to guide the user, as described in FIGS. . 10A to 10E, and the coating does not need to be placed on the card as part of a card manufacturing process.

In some embodiments of the 2200 method, the power source may comprise a display screen, speakers, and may include a headphone jack, in such embodiments, the smart card may provide status indications throughout the enrollment process via of the splash screen and speakers contained in the source

FIG. 23A is a flowchart illustrating another embodiment of a simple, cost effective method 2300 for enrolling a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a card. smart, without requiring entry of activation data (i.e. an activation code) before enrolling the fingerprint template.

In step 2302, a fingerprint enabled smart card is manufactured. During the manufacturing process, the fingerprint sensor on the fingerprint-enabled smart card is set to be in an enrollment mode by default when connected to a power source. In some embodiments, the card provider can optionally set the smart card status to inactive to prevent unauthorized use before the intended user can enroll a fingerprint template and contacts the card provider to activate the card.

In step 2304, the card provider provides the smart card and a simple, low-cost power source to the user, for example sent by mail or courier or given by a bank or retail store. In some embodiments, the power source can be battery powered, mains powered (eg via a USB connector), or solar powered. An exemplary non-limiting embodiment of the power source is described in FIGS. 9A to 9H. In some embodiments, if the smart card contains an on-board power source, such as a solar cell, an external power source is not required.

In step 2306, the user connects the smart card to the power source, for example, by inserting the card into a power source housing that has contacts for connecting one or more power transmission contacts of the smart card to the power source. power source without connecting any smart card data transmission contacts to a device configured to transmit data to or receive data from the card. Consequently, connecting the smart card to the power source does nothing but provide power to the electrical components of the smart card - for example LEDs, logic elements, sensor elements, etc. -, and the power source is unable to transmit data to or from the smart card.

In some embodiments, the smart card and power source can be delivered to the user with the smart card already inserted into the power source as described in FIG. 9A. In such embodiments, a battery connection tab is inserted between the power source and the smart card to keep a connection power disconnected. The user can pull out the battery connection tab, as shown in FIG. 12A, to connect the power supply to the smart card.

Connection to the power source can automatically activate the sleep mode

ΊΛ / t / ZUZU / UUU / JO inscription on the fingerprint sensor. In some modalities, the enrollment mode in the fingerprint sensor is activated once after a specific moment of connecting the card to the power source (for example the first, second, third, etc. connection of the smart card to The source of energy). The card remains in enrollment mode until it is disconnected from the power source or until registration is complete. If the card is disconnected from the power source before registration is complete, the card cannot be put back into enrollment mode by reconnecting the card to the power source, and the user may be required to take action. , such as contacting the card provider or obtaining a new card, to enable the card to be put into enrollment mode.

In some modalities, the user can activate the registration mode by connecting the card to the power source and not completing the registration. That is, the fingerprint sensor may be in the enrollment mode, but the user does not provide any input or insufficient input to the fingerprint sensor for the purposes of gathering enough acceptable images for a fingerprint template. In such modes, the fingerprint sensor can enter a power saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

In other embodiments, the fingerprint sensor enrollment mode is activated each time the smart card is connected to the power source until a fingerprint template is stored. In yet another embodiment, the fingerprint sensor enrollment mode can be activated each time the smart card is connected to the power source until a fingerprint template has been stored after the initial automatic activation after the moment. specific to connect the smart card to the power source.

The card receives power from the power source, and a status indicator on the smart card (for example an LED) indicates to the user that the one or more transmitting contacts

ΊΛ / t / ZUZU / UUU / JO power of the power source are connected to the power source (that is, the card is energized), that the fingerprint sensor is in enrollment mode, and the smart card is ready for registration to begin.

At step 2308, the user can now begin enrolling a fingerprint. The fingerprint is enrolled by storing a fingerprint template derived from a or more fingerprint images generated by placing a finger on the fingerprint sensor. The smart card must remain connected to the power source throughout the entire enrollment process. In the event that the smart card is disconnected from the power source during the enrollment process, the enrollment mode on the fingerprint sensor is automatically disabled. In some modes, reconnecting the smart card to the power source automatically activates enrollment mode on the fingerprint sensor until a fingerprint template is stored. That is, the enrollment mode can be activated automatically after power is applied to the card if the logic elements of the card detect that a fingerprint template has not been stored for the card. The enrollment process is complete when a sufficient fingerprint template is acquired and stored in the fingerprint sensor (eg one described in previously incorporated US Patent No. 9,684,813). Once the enrollment process is complete, enrollment mode is disabled on the fingerprint sensor. Consequently, connecting the smart card to the power source after a successful enrollment will no longer activate enrollment mode on the fingerprint sensor. In some embodiments, the status indicator can provide an indication to the user when an image is acceptable, for example by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example by the LED flashing many times. The status indicator can indicate to the user when enough acceptable images for the fingerprint template have been collected and confirm that the enrollment step was completed successfully, for example by the LED lighting for a longer period, such as 10 or more seconds. In other embodiments, more than one LED may blink in different colors to communicate the various indications described above. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

In step 2310, the user removes the smart card from the power source, thereby disconnecting the one or more power transmission contacts of the smart card from the power source. In some embodiments, the power source can be scrapped.

If the card provider sets the card status to inactive in step 2302, then the user must activate the card before attempting to use it. In step 2312, the

ΊΛ / t / ZUZU / UUUZ user contacts the card provider (for example by phone, app, internet, etc.) to activate the smart card. The user must provide acceptable user verification details to the card provider to activate the smart card. If the user is verified, the card provider sets the card status as active in their systems. The user can now use the card in the normal way to pay for items, but now requiring fingerprint verification to use the smart card. If the user is not verified, the card remains inactive and cannot be used.

FIG. 23B is a flow chart illustrating another embodiment of a simple, cost-effective method 2314 for enrolling a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a card. smart, without requiring entry of activation data (i.e. an activation code) before enrolling the fingerprint template.

At step 2316, a fingerprint enabled smart card is manufactured. In some embodiments, the card provider can optionally set the smart card status to inactive to prevent unauthorized use before the intended user can enroll a fingerprint template and contacts the card provider to activate the card.

At step 2318, the card provider provides the smart card and a simple low-cost power source to the user, for example sent by mail or courier or given by a bank or retail store. The power source can be battery powered, mains powered (eg via a USB connector), or solar powered. An exemplary non-limiting embodiment of the power source is described in FIGS. 9A to 9H. In some embodiments, if the smart card contains an on-board power source, such as a solar cell, an external power source is not required.

In step 2320, the user connects the smart card to the power source, for example, by inserting the card into a power source housing that has contacts for connecting one or more power transmission contacts of the smart card to the power source. power source without connecting any smart card data transmission contacts to a device configured to transmit data to or receive data from the card. Consequently, connecting the smart card to the power source does nothing but provide power to the electrical components of the smart card - for example LEDs, logic elements, sensor elements, etc. -, and the power source is unable to transmit data to or from the smart card.

ΊΛ / t / ZUZU / UUU / JO power and smart card to keep a connection power disconnected. The user can pull out the battery connection tab, as shown in FIG. 12A, to connect the power supply to the smart card.

At step 2322, one or more trigger events are detected that result in the fingerprint sensor being put into enrollment mode. An example trigger event may be based on a timer or counter not expiring. For example, in some embodiments, the triggering event may be to detect that the timer or counter has not expired. In such embodiments, a user can enroll a biometric template within a certain time after the fingerprint sensor is put into enrollment mode. In other embodiments, the triggering event may be to detect that the age of the smart card is under a certain age limit that is tracked, for example, by the timer or counter. In some embodiments, the counter can be incremented each time a biometric template has been successfully enrolled or whenever the smart card was used. In such embodiments, the triggering event may be to detect that the counter has not exceeded a predetermined threshold (eg, a predetermined number of biometric template enrollments or card uses).

Another example trigger event may include an occurrence of an error state. In some modes, a hardware or software component error can occur during registration. An error recovery procedure initiated in response to such hardware or software component error may be the triggering event. In such embodiments, the hardware or software component error would have to be a recoverable error (eg a minor error, a transient event, or a technical failure). Thus, the detection of a recoverable error that prevents completion of the enrollment process could cause the sensor to enter enrollment mode. In such embodiments, a non-recoverable error that occurs during enrollment (eg, a component on the card fails) might not initiate or constitute a trigger event.

Other example trigger events include detection of a flag set the last time the card was inserted into a card reader (for example a flag set when the card is inserted into a card reader that transmits data to or from the card and that instructs the card to enter enrollment mode the next time the card is connected to power), the lack of a fingerprint template enrolled on the card is detected, or it is detected that power has been supplied to the card. Yet another trigger event may be the detection that the card has been inserted into a power source that is connected only to the power contacts on the card and not to the data transmission contacts. Other events, or combinations of events, can be trigger events. The trigger event can be detected by the fingerprint sensor, or by another component on the card (for example the secure element module) or it can be detected as a result of the fingerprint sensor and other

ΊΛ / t / ZUZU / UUUZ JO component on the interacting card, for example a handshake. If a component other than the fingerprint sensor detects the trigger event, that component can signal the fingerprint sensor to enter enrollment mode.

In some embodiments, the enrollment mode can be triggered, but the user may not complete the enrollment. That is, the fingerprint sensor may be in the enrollment mode, but the user does not provide any input or insufficient input to the fingerprint sensor for the purposes of gathering enough acceptable images for a fingerprint template. In such modes, the fingerprint sensor can enter a power saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

In some modes, the card remains in enrollment mode until it is disconnected from the power source or until enrollment is complete. If the card is disconnected from the power source prior to completing enrollment, the process may move back to step 2322, whereupon an appropriate trigger event will result in the sensor being returned to enrollment mode, or alternatively the user may be required to take some action, such as contacting the card provider or obtaining a new card, to enable the card to be put into enrollment mode.

In some embodiments, the card receives power from the power source, and a status indicator on the smart card (for example an LED) indicates to the user that the one or more power transmission contacts of the power source are connected to the power source (that is, the card is energized), the fingerprint sensor is in enrollment mode, and the smart card is ready for enrollment to begin.

At step 2324, the user can now start enrolling a fingerprint. The fingerprint is enrolled by storing a fingerprint template derived from one or more fingerprint images generated by placing a finger on the fingerprint sensor. The smart card must remain connected to the power source throughout the entire enrollment process. In the event that the smart card is disconnected from the power source during the enrollment process, the enrollment mode on the fingerprint sensor is automatically disabled. In some embodiments, reconnecting the smart card to the power source moves the process back to step 2322, whereby an appropriate trigger event will result in the sensor being returned to enrollment mode. The enrollment process is complete when a sufficient fingerprint template is acquired and stored in the fingerprint sensor (eg one described in previously incorporated US Patent No. 9,684,813). Once the enrollment process is complete, the enrollment mode is disabled on the fingerprint sensor permanently or alternately, until a fresh trigger event occurs. In some embodiments, the status indicator can provide an indication to the user when an image is acceptable, for example by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example by the LED flashing many times. The status indicator can indicate to the user when enough acceptable images for the fingerprint template have been collected and confirm that the enrollment step was completed successfully, for example by the LED lighting for a longer period, such as 10 or more seconds. In another embodiment, more than one LED can blink in different colors to communicate the various indications described above. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

In step 2326, the user removes the smart card from the power source, thereby disconnecting the one or more power transmission contacts of the smart card from the power source. In some embodiments, the power source can be scrapped.

In some embodiments, the card provider can set the card status to inactive in step 2316. In such embodiments, the user must activate the card before attempting to use it. Consequently, the method 2314 for enrolling the biometric template may include an additional step 2328 in which the user contacts the provider of the card (eg by phone, application, internet, etc.) to activate the smart card. The user must provide acceptable user verification details to the card provider to activate the smart card. If the user is verified, the card provider sets the card status as active in their systems. The user can now use the card in the normal way to pay for items, but now requiring fingerprint verification to use the smart card. If the user is not verified, the card remains inactive and cannot be used.

FIG. 24 is a flow chart illustrating another embodiment of a simple method,

ΊΛ / t / ZUZU / UUU / JO cost effective 2400 to enroll a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a smart card, is described in detail then.

At step 2402, a data entry device, such as an overlay as described in FIGS. 3B and 13 or a sleeve as described in FIGS. 10A to 12C, temporarily connects to a fingerprint-enabled smart card. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the smart card and encrypted at a secure location during the smart card manufacturing process. The fingerprint sensor on the smart card can be calibrated during the manufacturing process and is set to data entry mode before the smart card is sent to the user. A data entry device, such as, for example, any of the coatings or sleeves described herein, can be placed on the card as a final or near-final step in the card manufacturing process. In some embodiments, the data entry device is temporarily placed on the card by applying a repositionable adhesive provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik can be applied to coating 302 to be temporarily placed over the portion of the card. card 104 including detection area 106.

At step 2404, the card provider provides the smart card to the user, eg, sent by mail or courier or given by a bank or retail store.

In step 2406, the user has access to a device, for example a smartphone, which can provide power wirelessly, for example via Near Field Communication, and thus, it is not necessary to provide a power source to the user. In some embodiments, the user may be provided with a power source to give the user the choice of using wireless power or wired power.

In step 2408, the user follows the instructions, received with the card, to obtain an activation code from the card provider. In some modalities, the user may be required to call a number, or the data entry device may have a QR® code that the user can scan with a smartphone, or the user may enter their online banking site or mobile application and indicate that you want to receive an activation code by SMS. Other security mechanisms for obtaining the activation code may be available in alternative modes. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 2410, the user places the smart card near the smart phone

ΊΛ / t / ZUZU / UUUZ JO in range for NFC connectivity, as shown in FIGS. 25A to 25D. As shown in FIGS. 25A through 25D, smart card 104 is positioned near a communication device 2502, such as a smart phone, in various configurations. In each configuration, the fingerprint sensor 102 on the smart card 104 is made accessible so that the user can touch the detection area of the fingerprint sensor 102 while keeping the smart card 104 within range of NFC. Smart card 104 is powered through NFC connectivity and a status indicator on smart card 104 can show the user that smart card 104 is ready to initiate enrollment. In some embodiments, the user can disable all connectivity to communication device 2502, except for NFC, to ensure that communication device 2502 is completely off the network during the enrollment process to add security. For example, user can turn off cellular data, Wi-Fi, Bluetooth, etc.

Referring again to FIG. 24, at step 2412, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code, eg, as described in FIGS. 2A, 3A and 3B, 10D, HA, 12A, 13, 17, 18, 19 and 20. The fingerprint sensor is configured to simply detect the presence of the finger on the remote or direct contact data entry keys in code entry and unlock mode. In some modes, the fingerprint sensor can be configured to detect peaks and valleys of the fingerprint in unlock code entry mode.

In some modes, the status indicator can indicate to the user that the entered code is correct or incorrect. If the code entered is incorrect, the user can make a predetermined number of additional attempts before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modalities, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card can block the user permanently.

In some embodiments, if one or two unsuccessful entries have been made, the number of unsuccessful entries can be stored in non-volatile memory. Consequently, even if power to the smart card is removed and reapplied, the smart card can still remember how many unsuccessful entries have been made. Consequently, the card cannot be reset to a full complement of attempts by disconnecting the card after a number of unsuccessful attempts that is less than the maximum number of attempts allowed.

In some embodiments a smart card state can be stored in the non-volatile memory of the card. For example, the different states may include: (i) state

ΊΛ / t / ZUZU / UUU / JO new which means the card is waiting for unlocking by entering a valid activation code; (I) unlocked status which means the card is unlocked but enrollment has not been successfully completed; (iii) active status which means that the card is unlocked and an enrollment has been successfully completed; and (iv) locked state which means that the card unlocking procedure has been tried without success.

In step 2414, if the activation code has been entered correctly, the user can now remove the data entry device from the card and begin enrollment of a fingerprint (enrollment mode). The smart card must remain in range for NFC connectivity to the smartphone throughout the enrollment process. In some embodiments, the status indicator can indicate to the user when an image is acceptable, for example, by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED. that blinks many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

In some modalities, the user can activate the registration mode by correctly entering the activation code and not completing the registration. That is, the fingerprint sensor may be in the enrollment mode, but the user does not provide any input or insufficient input to the fingerprint sensor for the purposes of gathering enough acceptable images for a fingerprint template. In such modes, the fingerprint sensor can enter a power saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

ΊΛ / t / ZUZU / UUU / JO

In step 2416, the user moves the smart card out of range of NFC connectivity to remove the smart card from the power source. In some embodiments, if the user disabled all connectivities on the device, except for NFC, in step 2410, the user can re-enable all connectivities on the device.

Consequently, the user has now successfully enrolled a fingerprint on the smart card through the simple, cost-effective 2400 method and can use the smart card in the normal way to pay for items, but now requires fingerprint verification. to use the smart card. In some embodiments, multiple users can enroll a fingerprint on the smart card, or one user can enroll multiple fingers on the smart card, using the method noted above. In such modes, the card can be programmed with multiple activation codes that are provided to each user. To enroll a new user / finger, a new activation code is entered.

In some embodiments of method 2400 for enrolling the biometric template, the data entry device can be provided as a sleeve and can guide the user for activation code entry as described in FIGS. 11A to 11C and 12A to 12C.

FIG. 26A illustrates a data entry device in the form of an overlay that includes data entry keys coupled to spatially associated distinct sensing areas in the fingerprint sensor sensing area, where the data entry keys are located remotely from the detection area according to some modalities. A portion of the detection area of the fingerprint sensor is exposed through a cut formed in the coating while another portion of the detection area is covered by the coating.

As shown in FIG. 26A, a data input device in the form of an overlay 2602 comprises a portion 2612 that covers a portion X (as shown by the dotted lines in FIG. 26A) of the detection area 106 of the fingerprint sensor installed in the smart card 104 and further comprises a cutout 2620 in the coating 2602 to expose a remaining portion Y of the detection area 106 of the fingerprint sensor. In an exemplary non-limiting embodiment, a smart card 104 is the device that contains the fingerprint sensor, but the application of the data entry device is not restricted to a smart card and can be used for any device that contains a fingerprint sensor. fingerprint in alternative modalities. In some embodiments, the cover 2602 is removably positioned over a portion of the card 104 including the X portion of the detection area 106, and exposing the Y portion of the detection area through the cut 2620 of the cover 2602. The cover 2602 includes data entry keys 2608A-D associated with (eg, coupled to) spatially distinct detection areas in the X portion of the detection area 106 of the fingerprint sensor. As shown in FIG. 26A, data entry keys 2608A-D can be

ΊΛ / t / ZUZU / UUU / JO located remotely from detection area 106.

In some embodiments, the overlay 2602 may comprise a drilled hole 2606 on the LED 308 or other indicator element on the card 104 when the overlay 2602 is placed on a portion of the card 104 including the detection area 106 and the LED 308. In In some modes, an OLED display can operate as the fingerprint sensor. In such embodiments, a portion of the OLED display that is included in the Y portion of the detection area 106 is configured to be used as the indicator element and a status indication is then visible through the cutout in the overlay.

In some embodiments, each data entry key 2608A-D may function to enable the user to enter numbers (for example an activation code, such as a PIN code) by tapping their finger in spatially different control areas 2608A-D . Each data entry key 2608A-D on overlay 2602 is electrically coupled to a spatially distinct associated portion of portion X of sensing area 106 so that contact with each key will result in a detectable signal from the element (s). ) sensor (s) of the associated portion spatially distinct from the detection area 106. The coupling between the 2608A-D keys and the detection area 106 allows the 2608A-D keys to be located remotely from the detection area 106. This provides the significant advantage of positioning the 2608AD keys in locations not restricted by the boundaries of the area. detection 106. For example, additional space on smart card 104 can be used to provide additional keys (eg more than four keys) or keys 2608A-D can be separated, which can improve user access. In other embodiments, the overlay 2602 may comprise a data entry key electrically coupled to a spatially associated portion of the sensing area 106 configured to receive Morse code type data input by the user.

FIGS. 26B to 26C illustrate upper and lower surfaces, respectively, of a data entry device in the form of an overlay that includes data entry keys coupled to distinct sensing areas associated spatially in the X portion of the sensing area of the device. fingerprint sensor and further including a cutout to expose the Y portion of the detection area of the fingerprint sensor according to some modalities.

As shown in FIGS. 26B to 26C, the coating 2602 comprises an upper surface 2604 and a lower surface 2605. A portion 2612 of the lower surface 2605 makes direct contact with the portion X of the detection area 106 which is smaller than the entire detection area 106 when coating 2602 is placed over detection area 106. In some embodiments, the coating is made of a non-conductive film, for example a thin polymeric film, and may be less than 100 microns thick.

ΊΛ / t / ZUZU / UUU / JO

As shown in FIG. 26B, the upper surface 2604 comprises data entry keys 2608A-D, a drilled hole 2606 for an LED 308 (as previously described in FIG. 26A) or other indicator element on the smart card 104, an optional tab 2610 for the easy removal of the coating 2602, and a cutout area 2620 to expose the Y portion of the detection area 106 of the fingerprint sensor. In some embodiments, the top surface 2604 may be a silk screen printed to indicate data keys 2608AD. In some embodiments, the edge surface surrounding each data entry key 2608AD may be slightly raised so that a user can feel the circumference of the holes when a finger is placed on it.

As shown in FIG. 26C, bottom surface 2605 comprises key indicia 2614A-D, connect indicia 2616A-D, detection area, drilled hole 2606 for LED 308 or other indicator element on smart card 104, and cutout area 2620 for expose the Y portion of the fingerprint sensor detection area. The data entry keys 2608A-D on the top surface align with the key indicia 2614A-D on the bottom surface. In some embodiments, a conductive material, such as conductive ink, metallization, conductive polymer, or any conductive coating can be used to print or apply key indicia 2614A-D, connect indicia 2616A-D, and activation indicia. 2618A-D detection area on the bottom surface 2605. The 2614A-D key indicia are located remotely from the 2618A-D sensing area activation indicia. Connect indicia 2616A-D connect key indicia 2614A-D to each respective associated detection area activation indicia 2618A-D. The detection area activation indicia 2618A-D is located on the lower surface 2605 so that the detection area activation indicia 2618A-D is aligned with associated spatially distinct data input regions of the X portion of the area of detection 106 when the overlay 2602 is placed on the smart card 104.

In an exemplary non-limiting implementation of coating mode 2602, when the fingerprint sensor is in control mode and data input mode, the sensor elements within portion 2612 (i.e., portion X) of detection area 106 are activated and scanned in the contact detection mode and the data entry keys 2608A-D are operatively coupled to associated spatially distinct activation indicia 2618A-D within portion 2612 (i.e., portion X) of detection area 106. When the coated fingerprint sensor 2602 is in the enrollment mode, only the sensor elements located within the portion 2620 (i.e., the Y portion) of the two-dimensional array of the detection area 106 can be activated and scanned in the enrollment mode. fingerprint detection, and the circuitry that controls the sensor is configured so that multiple images of a user's fingerprint can be put together to acquire a sufficient fingerprint template to be

ΊΛ / t / ZUZU / UUUr stores in memory. In the verification or authentication mode, the coating 2602 could typically have been removed from the card 104 (or other device), and the sensor elements from the entire detection area, including portion 2612 (i.e., portion X) and portion 2620 (ie, portion Y), are scanned in fingerprint detection mode to generate a fingerprint image for comparison against the fingerprint template created in enrollment mode.

FIG. 27A illustrates an arrangement of conductive material over the detection area of the fingerprint sensor. In this embodiment, the detection area activation indicia 2718A-D may be in the form of square blocks or rectangles in the X portion 2702 of the detection area 106. Figure 27A shows the X portion 2702 and the Y portion 2704 as two rectangles. non-overlapping, sharing a long side along the H direction. Arranging the X portion 2702 and the Y portion 2704 in this manner optimizes the area of the Y portion 2704, thereby providing better fingerprint matching performance. However, other implementations are possible, for example the X portion 2702 may be L-shaped or may even form a frame surrounding the Y portion 2704.

When the 2718A-D detection area trigger indicia are in the outline of a square block or a rectangle, there may be a loss in detection sensitivity because the 2718A-D detection area trigger indicia is not aligned with the total length of the pickup lines of the detection area 106. To compensate for any loss in detection sensitivity, the 2718A-D square or rectangle block detection area trigger indicia may be wider along the length of the detection area, that is, the H direction, than the height in the width of the detection area in the G direction to cover more capture lines. In some embodiments, the X portion 2702 of the detection area 106 covers about 5-20% of the total detection area 106. In some embodiments, for a 9mm x 9mm fingerprint sensor with 6 data entry indicia, each 2718A-D sensing area trigger indicia is approximately 1mm square, evenly distributed along one side of the target area. detection 106.

FIG. 27B illustrates an embodiment of arranging conductive material over the fingerprint sensor detection area that includes activation indicia in a portion of the sensing area connected to data keys and reference indicia arranged between and adjacent to the activation indicia. . In some embodiments, detection area 2718A-F activation indicia of equal size and profile are uniformly distributed over portion X 2702 of detection area 106, and reference indicia 1502A-G are evenly distributed among each neighboring pair of detection area activation indicia 2718A-F (and adjacent to each outermost activation indicia 2718A and 2718F) so that reference indicia 1502A- G are aligned with spatially distinct associated reference regions of the X portion 2702 of the

ΊΛ / t / ZUZU / UUUr detection 106. In some embodiments, reference indicia 1502A-G are the same size and profile as activation indicia 2718A-F. Detection area activation indicia 2718A-F are connected via connection indicia 1416A-F to corresponding key indicia (not shown). Reference indicia 1502A-G are not connected to the key indicia but are subject to unwanted signal inputs and noise in a manner similar to that of detection area activation indicia 2718A-F. In some embodiments, during the sensor scan process, the detected signals from the sensor elements covered by the reference indicia 1502A-G (also referred to as reference signals) can be subtracted from the detected signals from the sensor elements covering the elements. 2718A-F trigger cues (also referred to as trigger signals) to remove noise and unwanted signals. In some embodiments, the reference signals can be subtracted from the drive signals by the differential amplifier, as described above in connection with FIG. 15D.

FIG. 27B illustrates reference indicia 1502A-G and sensor activation indicia 2718A-F that are uniformly distributed in the X portion 2702 and of equal size and profile. However this is not required and the reference indicia 1502A-G and sensor activation indicia 2718A-F may have any appropriate size and profile in any appropriate distribution in the X portion 2702 in alternate embodiments.

FIG. 28 illustrates the data entry device in the form of an overlay 2602 temporarily placed on the smart card 104 according to some embodiments. To aid in illustration, the top surface is not shown and the overlay 2602 is shown as transparent so that the bottom surface 2605 can be seen in contact with the fingerprint sensor. As shown in FIG. 28, the overlay 2602 covers a portion of the smart card 104 that contains the detection area 106. The overlay 2602 is placed on the smart card 104 so that the detection area activation indicia 2618A-D in the lower layer 2605 they are covering and aligned with the spatially discrete regions of the X portion 2702 of the detection area 106 (encompassing one or more specified sensing elements) associated with each key indicia 2614A-D. The cut area 2620 in the single layer coating 2602 exposes the Y portion 2704 of the detection area 106.

FIGS 29A and 29B illustrate devices containing fingerprint sensors with data entry keys built into the device according to some embodiments. In some embodiments, the data keys may be a permanent feature of the device and are not in a temporary overlay.

FIG. 29A shows an example of a smart card 104 according to some embodiments. Smart cards are typically made from multiple layers of plastic, some layers incorporating circuitry and possibly an antenna. In some

ΊΛ / t / ZUZU / UUU / JO modes, the data input keys 2902A-F can be incorporated into a layer of the card body itself, and the Y portion 2704 of the detection area of the fingerprint sensor 102 can be exposed on an upper surface of the card body. In a lower layer, the key indicia can be coupled with data entry keys 2902A-F in the upper layer. The connect indicia (not shown) connect the key indicia to the X portion 2702 of the detection area of the fingerprint sensor 102. In some embodiments, the data entry keys 2902A-F are partially ground off the body of the fingerprint sensor. the card to reduce the thickness of the card body between the key and the underlying key indicia. Partial grinding outside of the card body can assist the user in locating the data entry keys by touch.

FIG. 29B shows an example of a device such as a smart watch or exercise monitor, according to some embodiments. However, the principles applied to the device described in FIG. 29B are not restricted to the smart watch or fitness monitor, and the principles also apply to other devices with limited user interfaces such as radio keys, remote controls, instrument panels, appliances, and industrial equipment in alternate modes. As shown in FIG. 29B, the data entry keys 2902G-H, and the Y portion 2704 of the detection area of the fingerprint sensor are permanently available to the user on the upper surface of the device. In an underlying layer, the key hints can be docked with the 2902G-H data entry keys. As described above in FIG. 29A, the connection indicia (not shown) connects the key indicia to the X portion 2702 of the fingerprint sensor detection area.

Unlike existing smart cards or items incorporating keyboards, the embodiments described in FIGS. 29A and 29B offer the manufacturer the opportunity to reduce component costs by using the fingerprint sensor to implement the keyboard in addition to offering biometric services. In the specific case of a contactless smart card containing a fingerprint sensor and data entry keys, the modality described in FIG. 29A can be particularly advantageous to save on additional circuitry and processing logic components. In contactless smart cards, the fingerprint sensor 102, which works alone, or in conjunction with other components on the card 104, may be capable of harvesting energy from an NFC signal to provide fingerprint authentication when placed in range of a wireless power device according to some modalities. In such modes, the same power harvesting circuitry and power handling processing capabilities already used by the contactless smart card for fingerprint authentication purposes can be employed to wirelessly power the card when input is required. data.

ΊΛ / t / ZUZU / UUU / JO intelligent FIG. 29A or the device of FIG. 29B, when the fingerprint sensor 102 is in the control mode and data input mode, the sensor elements within the data input detection area X 2702 of the detection area 106 are activated and scanned in the data detection mode. contact and data entry keys are operatively coupled to spatially distinct associated sensor elements within the data entry detection area X of the detection area. When the fingerprint sensor 102 is in the enrollment mode, only the sensor elements located within the exposed detection area Y 2704 of the two-dimensional array of the detection area 106 can be activated and scanned in the fingerprint detection mode, and the circuitry that controls the sensor is configured so that multiple images of a user's fingerprint can be put together to acquire a sufficient fingerprint template that is stored in memory. In the verification or authentication mode, only the sensor elements located within the exposed detection area Y 2704 of the two-dimensional array of the detection area 106 can be activated and scanned in the fingerprint detection mode, and the circuitry they control the sensor is configured to generate a fingerprint image for comparison against the fingerprint template created in enrollment mode.

As described above, the detection area 106 of the fingerprint sensor 102 installed in the device 104 can be selectively configured to operate in five modes: (1) enrollment mode; (2) verification mode; (3) data entry mode; (4) control mode; and (5) unlock mode. In some embodiments, the user can select different modes through different interactions with sensor 102, such as double tapping, hold, drag up / down, and drag left / right in the detection area 106. In In other embodiments, the sensor 102 can be selectively configured in different modes when the user presses the data entry keys that engage the detection area 106.

However, the embodiments shown in FIGS. 26A and 29A and 29B additionally offer the user the ability to operate in more than one mode simultaneously. For example, if the user were to put an enrolled finger in detection area Y 2620, 2704 and at the same time, press one or more data input keys, the fingerprint sensor can capture a single image of the sensor that could detect fingerprint image (in Y area 2620, 2704) and could detect which data entry key (s) was pressed (in X area 2612, 2702) at that time. This offers a whole new set of possibilities to be able to interact with a host device in a safe mode as it allows the owner of the host device to verify its identity at the exact moment the owner is making an additional entry. Some examples of how this feature can be used, for example the host device can only be

ΊΛ / t / ZUZU / UUU / JO locked / unlocked / reset if the verified user of the device is detected when the lock / unlock / reset key is pressed, or certain features on the host device can be activated only if the user is verified at the same time that a certain key is pressed, or a payment can only be taken from the user's account if the user is verified at the same time as their input oppression to authorize the payment, and so on. The features also prevent accidental data entry, for example if a user's biometrically enabled radio key is in their handbag, if something in the bag is pressed against the radio key and hits the unlock button, the car will not. it will be unlocked because your fingerprint has not been simultaneously detected.

FIGS. 30 and 31 show flowcharts describing an enrollment process 3000 and 3100, respectively, where the Y portion 2620 of the detection area 106 of the fingerprint sensor 102 is exposed to the user through a data entry device in the form of a coating constructed as described in FIGS. 26B and 26C. Since the Y portion 2620 of the detection area 106 is exposed, after the activation code (PIN) has been entered, the user does not need to remove the coating until after the user has enrolled their finger, or optionally, the user can leave the coating on the device.

With reference to FIG. 30, at step 3002, a data entry device, such as a data entry device as shown in FIGS. 26B and 26C temporarily connect to a biometric enabled device, such as a fingerprint enabled smart card. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the smart card and encrypted at a secure location during the smart card manufacturing process. In some embodiments, the fingerprint sensor on the smart card can be calibrated during the manufacturing process and set to data entry mode before the smart card is sent to the user.

At step 3004, the card provider provides the smart card and a simple low-cost power source to the user, for example sent by mail or courier or given by a bank or retail store. In some embodiments, the power source can be battery powered, mains powered (eg via a USB connector), or solar powered. An exemplary non-limiting embodiment of the power source is described in FIGS. 9A and 9H. In some embodiments, if the smart card contains an on-board power source, the power source need not be provided to the user.

In some embodiments, the smart card and power source can be delivered to the user with the smart card already inserted into the power source as described in FIGS. 11A and 11C and 12A and 120. In such embodiments, a battery connection tab is inserted between the power source and the smart card to keep a power disconnected.

ΊΛ / t / ZUZU / UUU / JO connection. The user can pull out the battery connection tab, as shown in FIG. 12A, to connect the power supply to the smart card.

In step 3006, the user follows the instructions, received with the card, to obtain an activation code from the card provider. For example, the user could be prompted to call a number, or the data entry device could have a QR® code that the user can scan with a smartphone, or the user could enter your online banking site or application. mobile and indicate that you want to receive an activation code by SMS. Other security mechanisms for obtaining the activation code may be available in alternative modes. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 3008, if not already done, the user connects the smart card to the power source, for example by inserting the card into a power source housing. The card receives power from the power source, and a status indicator on the smart card (for example an LED) indicates to the user that the smart card is ready.

In step 3010, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code. The status indicator can indicate to the user that the code entered is correct or incorrect. As described above, if the code entered is incorrect, the user can make a predetermined number of additional attempts before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modalities, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card blocks the user.

In step 3012, if the activation code has been entered correctly, the user can now initiate fingerprint enrollment (enrollment mode) without removing the data entry device from the card. The smart card must remain connected to the power source throughout the entire enrollment process. In some embodiments, the status indicator indicates to the user when an image is acceptable, for example, by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED that blinks many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible display such as an OLED panel can be used to

ΊΛ / t / ZUZU / UUUZ provide textual feedback during the registration process.

In step 3014, the user removes the smart card from the power source. In some embodiments, the power source can be scrapped. In some embodiments, the user can optionally also remove the data entry device after successful enrollment, possibly after additional data entry.

Consequently, the user has now successfully enrolled a fingerprint on the smart card through the 3000 enrollment process and can use the smart card in the normal way to pay for items, but now requires fingerprint verification to use the Smart card. In some embodiments, multiple users can enroll a fingerprint on the smart card, or one user can enroll multiple fingers on the smart card, using the above method 3000. In such embodiments, the card can be programmed with multiple activation codes that are provided to each user. To enroll a new user / finger through enrollment process 3000, a new activation code is entered, which is made convenient by the fact that the data entry device was not removed during the previous fingerprint enrollment.

With reference to FIG. 31, at step 3102, a data entry device, such as a data entry device as shown in FIGS. 26A and 26C temporarily connect to a biometric enabled device, such as a fingerprint enabled smart card. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the smart card and encrypted at a secure location during the smart card manufacturing process.

In step 3104, the card provider provides the smart card to the user, eg, sent by mail or courier or given by a bank or retail store.

In step 3106, the user has access to a device, for example a smart phone, which can provide power wirelessly, for example via Near Field Communication, and thus, it is not necessary to provide a power source to the user. In some embodiments, a power source may optionally be provided to the user to give the user the choice of using wireless power or wired power.

In step 3108, the user follows the instructions, received with the card, to obtain an activation code from the card provider. For example, the user could be required to call a number, or the data entry device could have a QR® code that the user can scan with a smartphone, or the user could enter your online banking site or application. mobile and indicate that you want to receive an activation code by SMS. Other security mechanisms for obtaining the activation code may be available in alternative modes. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 3110, the user places the smart card near the smart phone in range for NFC connectivity, for example, as shown in FIGS. 25A and 25D. The smart card is powered by NFC connectivity and a status indicator shows the user that the smart card is ready for enrollment to begin. In one embodiment, the user could disable all connectivity on the device, except for NFC, to ensure that the device is completely off the network during the enrollment process to add security. For example, user can turn off cellular data, Wi-Fi, Bluetooth, etc.

At step 3112, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code. The status indicator can indicate to the user that the code entered is correct or incorrect. If the code entered is incorrect, the user can make a predetermined number of additional attempts before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modes, if the number of unsuccessful attempts reaches the limit or the code

Activation ΊΛ / t / ZUZU / UUU / JO is not entered before a preset time has passed, the smart card blocks the user.

In some embodiments, if one or two unsuccessful entries have been made, the number of unsuccessful entries is stored in non-volatile memory. Consequently, even if power to the smart card is disconnected and reapplied, the smart card still remembers how many unsuccessful entries have been made. Consequently, the card cannot be reset to a full complement of attempts by disconnecting the card after a number of unsuccessful attempts that is less than the maximum number of attempts allowed.

At step 3114, if the activation code has been entered correctly, the user can now initiate fingerprint enrollment (enrollment mode) without removing the data entry device from the card. The smart card must remain in range for NFC connectivity to the smartphone throughout the enrollment process. In some embodiments, the status indicator can indicate to the user when an image is acceptable, for example, by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED. that blinks many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

ΊΛ / t / ZUZU / UUUZ JO fingerprint sensor wakes from power-saving sleep mode and completes the enrollment process.

In step 3116, the user moves the smart card out of range for NFC connectivity to remove the smart card from the power source and optionally removes the data entry device. In some embodiments, if the user disabled all connectivities on the device, except for the NFC, in step 3110, the user can re-enable all connectivities on the device.

FIGS. 32 and 33 are flowcharts showing the 3200 and 3300 enrollment process, respectively, in a device as illustrated in FIGS 29A and 29B where the data entry keys 2902A-F, 2902G-H and the Y portion 2704 of the fingerprint sensor 102 are permanently available to the user.

With reference to FIG. 32, at step 3202, data entry keys are embedded in a fingerprint-enabled smart card or other device. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the device and encrypted in a secure location during the device manufacturing process. In some embodiments, the fingerprint sensor in the device can be calibrated during the manufacturing process and set to data entry mode before the smart card is sent to the user.

At step 3204, the provider of the device provides the device and a simple, low-cost power source to the user, for example sent by mail or courier or given by a bank or retail store. In some embodiments, the power source can be battery powered, mains powered (eg via a USB connector), or solar powered. An exemplary non-limiting embodiment of the power source is described in FIGS. 9A and 9H. In some embodiments, if the device contains an on-board power source, the power source need not be provided to the user.

In some embodiments, a smart card and the power source can be delivered to the user with the smart card already inserted into the power source as described in FIGS. 11A and 11C and 12A and 12C. In such embodiments, a battery connection tab is inserted between the power source and the smart card to keep a power connection disconnected. The user can pull out the battery connection tab, as shown in FIG. 12A, to connect the power supply to the smart card.

In step 3206, the user follows the instructions, received with the device, to obtain an activation code from the device provider. For example, the user could be prompted to call a number, or the data entry device could have a QR® code that the user can scan with a smartphone, or the user could enter your banking site.

ΊΛ / t / ZUZU / UUU / JO online or mobile application and indicate that you want to receive an activation code by SMS. Other security mechanisms for obtaining the activation code may be available in alternative modes. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 3208, if not already done, the user connects the device to the power source, for example by inserting the device into a power source housing. The device receives power from the power source, and a status indicator on the device (for example an LED) indicates to the user that the device is ready.

At step 3210, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code. The status indicator can indicate to the user that the code entered is correct or incorrect. As described above, if the code entered is incorrect, the user can make a predetermined number of additional attempts before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modalities, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card blocks the user.

In step 3212, if the activation code has been entered correctly, the user can now initiate enrollment of a fingerprint (enrollment mode). The device must remain connected to the power source throughout the entire enrollment process. In some embodiments, the status indicator can indicate to the user when an image is acceptable, for example, by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED. that blinks many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

ΊΛ / t / ZUZU / UUU / JO can enter a power-saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

In step 3214, the user removes the device from the power source.

Consequently, the user has now successfully enrolled a fingerprint in the device according to the 3200 process and can use the device in the normal way, but now requires fingerprint verification to use the device. In some embodiments, multiple users can enroll a fingerprint on the device, or one user can enroll multiple fingers on the device, using the method noted above. In such modes, the device can be programmed with multiple activation codes that are provided to each user. To enroll a new user / finger according to the 3200 process, a new activation code is entered, which is convenient due to the fact that the data entry keys are permanently incorporated into the device.

With reference to FIG. 33, process 3300 begins with step 3302, in which data entry keys are embedded in a fingerprint-enabled smart card or other device. In some embodiments, a unique code, such as an activation code, is written to a secure memory of the device and encrypted in a secure location during the device manufacturing process. The fingerprint sensor on the device can be calibrated during the manufacturing process and is set to data entry mode before the smart card is sent to the user.

In step 3304, the device vendor provides the device to the user, eg, sent by mail or courier or given by a bank or retail store.

In step 3306, the user has access to a device, for example a smartphone, that can provide power wirelessly, for example via Near Field Communication, and thus, it is not necessary to provide a power source to the user. In some

ΊΛ / t / ZUZU / UUUr modalities, a power source can be provided to the user to give the user the choice of using wireless power or wired power.

In step 3308, the user follows the instructions, received with the device, to obtain an activation code from the device provider. For example, the user could be required to call a number, or receive a QR® code that the user can scan with a smartphone, or the user could enter their online banking site or mobile application and indicate that they want to receive a activation code by SMS.

In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 3310, the user places the device near the smartphone in range for NFC connectivity, for example, as shown in FIGS. 25A and 25D. The device is powered through NFC connectivity and a status indicator shows the user that the smart card is ready for enrollment to begin. In one embodiment, the user could disable all connectivity on the device, except for NFC, to ensure that the device is completely off the network during the enrollment process to add security. For example, user can turn off cellular data, Wi-Fi, Bluetooth, etc.

At step 3312, the user enters the activation code by sequentially tapping the data entry keys in a sequence corresponding to the activation code. The status indicator can indicate to the user that the code entered is correct or incorrect. If the code entered is incorrect, the user can make a predetermined number of additional attempts before the smart card locks the user permanently. For example, the user can get three attempts to correctly enter the code. In some modalities, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card blocks the user.

In step 3316, the user moves the smart card out of range of NFC connectivity to remove the smart card from the power source. In some embodiments, if the user disabled all connectivities on the device, except for the NFC, in step 3310, the user can re-enable all connectivities on the device.

FIGS. 34A and 34E illustrate another embodiment of a data entry device in the form of an overlay 3402. As shown in FIGS. 34A and 34E, coating 3402 integrates a power source (also referred to as a non-data transmitting power source) for the fingerprint sensor 102 installed in a device 104 as well as data entry elements for entering data via generated signals. on the fingerprint sensor. In the

ΊΛ / t / ZUZU / UUU / JO modality described in relation to FIGS. 34A and 34E, a smart card is the device that contains the fingerprint sensor. However, the application of the data entry device is not restricted to a smart card and can be used for any device that contains a fingerprint sensor in alternative modes. In some embodiments, smart card 104 comprises fingerprint sensor 102 with a detection area 106, possibly LEDs or other status indicators 308, and contact plates 108 that provide contacts for an external power source.

In some embodiments, the coating 3402 comprises a thin material, for example a film that conforms to a surface of the host device when secured thereto. In some embodiments, the coating 3402 is an adhesively backed label or film temporarily and removably placed on the card. In some embodiments, repositionable adhesives provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik can be applied to the coating 3402 to be temporarily placed on the portion of the card 104 including the contact plates 108. In other embodiments, the temporary covering 3402 can be slipped over the device, clamped over the device, or folded over the device rather than adhering to the surface of the device. In some embodiments, the coating can be magnetic and stick to the surface of the device if the device is metal.

FIG. 34A is a plan view of one embodiment of a data input device in the form of a shroud 3402 that integrates a power source with a host device (eg smart card) disposed below the shroud. Features arranged on the back, or unexposed surface, of coating 3402 or features arranged on the underlying host device that are covered by coating 3402 are shown in dashed lines in FIGS. 34A, 34B, and 34F. The overlay 3402 is configured to provide power to an electronic device 104, such as a smart card, which has terminals (for example power connection boards) to connect a source of electrical power to the electronic device 104, and the overlay 3402 is configured to be removably secured to a surface of electronic device 104.

In some embodiments, coating 3402 is not secured to the surface of device 104, but is connected to device 104 via a ribbon cable or other conductor. For example, a power source, such as that shown in FIGS. 34A and 34F and 35, may be incorporated into a remote keypad device 1902 shown in FIG. 19, and data transfer cable 1906 may also include conductive contacts to connect the power source to the power transmission boards of host device 104.

In some embodiments, the coating 3402 may comprise an element of

ΊΛ / t / ZUZU / UUU / JO

100 adequate power 3404 to power card 104, such as an LR44 small cell battery. In such embodiments, the power element 3404 is securely attached to the coating 3402 and makes electrical contact with the contact plate of the power element 3406. For example, a terminal of a battery may contact the contact plate of the power element. 3406. As shown in FIG. 34A, the contact plate of the power element 3406 makes contact with the power connection indicia 3410A. A corresponding conductive contact 3408 is printed or etched onto a section of the coating 3402 that can be folded so that the conductive contact 3408 aligns with the energy element 3404. In some embodiments, pressure applied to the folded conductive contact 3408 maintains contact conductive 3408 in contact with power element 3404. For example, conductive contact 3408 makes contact with another battery terminal. In some embodiments, conductive contact surface 3408 may be coated in repositionable, conductive adhesive so that the collapsible cover section will remain in contact with power element 3404 without the user having to continue to hold it in place. Conductive contact 3408 further contacts power connection indicia 3410B.

In some embodiments, the 3410A and 3410B power on indicia are printed in conductive ink or etched into the coating 3402. The 3410A power on indicia routes the 3404 power element and the 3406 power element contact plate to ground 3414 on contact plate 108. The power connection indication 3410B routes the conductive contact 3408 to the power input of the card contact at the contact plates 108 on the smart card 104. Moving conductive contact 3408 in contact with power element 3404 (i.e. so that conductive contact 3408 makes contact with a portion (for example the terminal) of power element 3404 and power element contact plate 3406 makes contact with another part (eg terminal) of energy element 3404) completes a circuit of conductive contact 3408, through energy element 3404, and to the contact plate of energy element 3406. The overlay 3402 includes a circuit breaker configured to enable a user to selectively close a power circuit between the power element 3404 and the terminals of the electronic device to enable transmission of energy between the power element and the electronic device. In some embodiments, the loop closure includes a section of liner 3402 that contains conductive contact 3408 folded (for example, over a bend line 3407 shown in FIG. 34A) so that when conductive contact 3408 contacts a contact element power 3404 The power circuit source is completed and power is supplied to the board 104. In some embodiments, conductive contact 3408 can be kept in contact with power element 3404 by applying pressure to conductive contact 3408. For example, the pressure can be

ΊΛ / t / ZUZU / UUU / JO

101 applied by a squeeze or squeeze, by a conductive adhesive between conductive contact 3408 and power element 3404 or by mechanical means, such as a clamp or clamp.

In some embodiments, overlay 3402 may include data entry keys 2608A-F, connection indicia 2616A-F coupling each data entry key with an associated, spatially distinct portion (part of X portion 3401) of the detection area 106 of the fingerprint sensor, and a cutout 2620 exposing a Y portion 3403 of the detection area 106 as previously described.

FIG. 34B is a view of the cover 3402 and host device with a portion of the cover folded over to complete a power circuit for the host device according to some embodiments.

FIG. 34B shows the result of folding a section of shroud 3402 to align conductive contact 3408 and power element 3404 to complete the power source circuit and provide power to card 104. In some embodiments, status indicators 308, eg light elements (eg LEDs) and / or other visual and auditory elements, can be used to signal to the user that power is present and / or that the enrollment process can begin.

In some embodiments the coating 3402 may be transparent or translucent so that its various elements and their alignments with the associated elements of the smart card 104 can be seen. However, this is not required and the coating may not be transparent or translucent in alternative modalities.

FIG. 34C is a plan view illustrating a covering surface 3402 that is placed in contact with the card 104 in accordance with some embodiments. Card 104 and power element 3404 are not shown in FIG. 34C. The coating surface 3402 shown in FIG. 34C makes contact with the surface of the card 104 and includes the power connection indicia 3410A, 3410B and the contacts of the card 3412, 3414 that make contact with the power plates (e.g. power terminals) of the contact plates 108 when coating 3402 is applied to card 104. FIG. 34D is a plan view illustrating a card 104 placed in the overlay 3402 according to some embodiments. In some embodiments, cover 3402 includes a rectangular portion having a size (eg, length and width) and profile corresponding generally to the size and profile of card 104, and the cover 3402 is positioned on the card 104 with three edges defining three sides of the rectangular portion aligned with the three corresponding edges of the card 104 to help ensure that the cover 3402 is properly positioned relative to the card 104 so that the power contacts 3412, 3414 of the coating 3402 align with the appropriate plates of the plates 108 of the card 104 and so that the cutout 2620 aligns

102 appropriately with the detection area 106 of the card 104.

In an exemplary non-limiting implementation of the coating mode 3402, when the fingerprint sensor is in control mode and data entry mode, sensor elements within a portion (X portion 3401) of detection area 106 covered by overlay 3402 are activated and scanned in contact detection mode and data entry keys 2608A-D are operatively coupled to associated distinct activation indicia spatially within the X portion 3401 of the detection area 106 that is covered by part of the coating 3402. When the coated fingerprint sensor 3402 is in the enrollment mode, only the sensor elements located within the Y portion 3403 of the two-dimensional array of the detection area 106 exposed by the cutout 2620 can be activated and scanned in the detection mode. fingerprint, and the circuitry that controls the sensor is configured so that multiple images of a user's fingerprint can be put together to acquire a sufficient fingerprint template that is stored in memory. In the verification or authentication mode, the overlay 3402 could typically have been removed from the card 104 (or other host device in alternate modes), and the sensing elements from the entire detection area 106, including the X portion 3401 and the And 3403, they are scanned in the fingerprint detection mode to generate a fingerprint image for comparison against the fingerprint template created in the enrollment mode.

FIG. 34E is a plan view of an overlay top surface 3402 (ie, the surface not in contact with the smart card) according to some embodiments. The user can make contact with the surface shown in FIG. 34E when coating 3402 is applied to card 104.

In some embodiments of the 3402 coating, the power element may be a USB outlet. In such embodiments, the USB outlet can be connected to the power and ground inputs of the contact plates 108 via power connection signs 3410A and 3410B. Circuit closure can be established by inserting a USB cable into the outlet and connecting the 3402 jacket to the main line.

In some embodiments of the coating 3402, the power element may be a solar cell with a pull tab cover. In such embodiments, the solar cell can be connected to the power and ground inputs of the contact plates 108 via power connection indicia 3410A and 3410B. Circuit closure can be established by removing the pull tab that covers the solar cell, thus exposing it to light.

In some embodiments of shroud 3402, the power element may be an NFC transceiver, mounted on shroud 3402. In such embodiments, the NFC transceiver may be connected to the power and ground inputs of contact plates 108 via clues.

ΊΛ / t / ZUZU / UUU / JO

103 3410A and 3410B Power Connection Device and is capable of harvesting power from an NFC-enabled device such as a mobile phone or card reader. Loop closure can be established by placing the card 104 within range of the NFC-enabled device and holding it in range until the desired process is completed.

As shown in FIGS. 34A and 34C, in some embodiments, the coating 3402 may further comprise a portion 2612 that covers the X portion 3401 of the detection area 106 of the fingerprint sensor installed on the smart card 104, and a cut 2620 in the coating 3402 to expose the remaining portion Y 3403 of the detection area 106 of the fingerprint sensor. Overlay 3402 includes data entry keys 2608A-F associated with (for example, coupled to) spatially distinct detection areas in X portion 3401 of fingerprint sensor detection area 106 by connection indicia 2616A-F. Data entry keys 2608A-F can be remotely located from detection area 106.

In some embodiments, as described above, each 2608A-F data entry key may function to enable the user to enter numbers (eg, an activation code, such as a PIN code) by touching a 2608A data entry key. -F with one finger. Each data entry key 2608A-F of overlay 3402 is electrically coupled to a spatially distinct associated portion of X portion 3401 of sensing area 106 so that contact with each key will result in a detectable signal from the element (s) ( s) sensor (s) of the associated portion spatially distinct from the detection area 106. The coupling between keys 2608A-F and sensing area 106 allows keys 2608A-F to be remotely located from sensing area 106. This provides the significant advantage of positioning keys 2608A-F in locations not restricted by boundaries. detection area 106. For example, additional space on smart card 104 can be used to provide additional keys (eg more than four keys) or keys 2608A-F can be separated, which can improve user access. In some embodiments, the overlay 3402 may comprise a data entry key electrically coupled to a spatially different associated portion of the detection area 106 configured to receive Morse code type data input by the user.

In some embodiments, the overlay 3402 may comprise a portion covering the fingerprint sensor installed on the smart card 104, but additionally including the data entry keys associated with (for example coupled to) spatially distinct detection areas in the area. detection area 106 of the fingerprint sensor where the data entry keys are located in the detection area 106, as shown in FIG. 3B, or where the data entry keys are located remotely from the detection area 106 as shown in FIG. 13. In both of these scenarios, the portion of coating 3402 that covers the

ΊΛ / t / ZUZU / UUUZ

104 Fingerprint sensor may be detachable from the section of the coating 3402 comprising the power source connected to the power inputs of the smart card 104. For example, the coating 3402 can be in two parts, or is perforated, or the coating it has two layers one on top of the other - where the section containing the data entry keys is the topmost. Thus, after the user has entered data using the data entry keys, the fingerprint sensor can be revealed to complete the enrollment, without interrupting the power supply to the card 104. When enrollment is complete, the portion remainder of the 3402 coating can be removed.

In some embodiments, a 3402F coating, as shown in FIG. 34F, does not cover the detection area 106 or fingerprint sensor 102 of the host device 104. Rather, the coating 3402F simply covers the portion of the card 104 including the contact plates 108. In some embodiments, the coating 3402F may comprise a power element 3404 disposed on a power element contact plate 3406, a conductive contact 3408, a power connection indicia 3410A connecting the power element contact plate 3406 to the board contact ground 3414, which connects to a power contact plate of contact plates 108, and the power connection indicia 3410B connecting conductive contacts 3408 to card contact power input 3412, which connects to another power contact plate of contact plates 108. In some embodiments, the coating 3402F may be strictly a power source for a smart card 104 or other device and does not include data entry functionality. The 3402F overlay can be used in combination with data entry devices, such as those shown in FIGS. 3B, 13, and 26A through 26C and discussed herein.

In some embodiments, the data input device in the form of an overlay 3402 may comprise a drilled hole 2606 on the LED 308 or other indicator element on the card 104 when the overlay 3402 is placed on a portion of the card 104 including the detection area 106 and LED 308. In other embodiments, an OLED display can operate as the fingerprint sensor. In such embodiments, a portion of the OLED display that is included in the Y portion 3403 of the detection area 106 can be configured to be used as the indicating element and thus a status indication is visible through the cutout 2620 in the overlay. 3402.

In some embodiments, the overlay 3402 may comprise one or more LEDs or other status indicators (eg visual, audible, tactile indicators) used to indicate status to the user during enrollment in a situation where there are no status indicators on the itself. smart card, or where the status indicators on the smart card are inappropriate. In such embodiments, a component on smart card 104, such as the

105 fingerprint sensor, secure element module, or other processing circuitry that monitors the status of the enrollment process and modulates a power line on card 104 in a known manner, depending on the status of the enrollment process. Overlay 3402 may further comprise detection circuitry configured to detect power line modulation and activate the one or more LEDs accordingly to indicate the correct status of the enrollment process.

FIG. 35 illustrates one embodiment of a power source coating (also referred to as a non-data transmitting power source) 3502 according to some embodiments. As shown in FIGS. 34A through 34F, the power source coating 3502 comprises a power element 3504 for the fingerprint sensor 102 installed in a device 104. In the illustrated embodiment shown in FIG. 35, a smart card is the device that contains the fingerprint sensor, but the application of the 3502 power source coating is not restricted to a smart card and can be used for any device that contains a fingerprint sensor in alternate modes . Card 104 comprises fingerprint sensor 102 with a detection area 106, LEDs or other status indicators 308, and contact plates 108 that provide contacts for an external power source.

In the illustrated embodiment shown in FIG. 35, overlay 3502 is an adhesively backed label or film that can be temporarily and removably placed on card 104. In one embodiment, repositionable adhesives provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik can be applied to the overlay 3502 to be temporarily positioned over the portion of the card 104 including the contact plates 108. In some embodiments, temporary covering 3502 may be slid over device 104, clamped over device 104, or folded over device 104 rather than being adhered to the surface of the device. In some embodiments, the temporary coating can be magnetic and stick to the surface of the device if the device is metallic.

In some embodiments, the coating 3502 comprises a suitable power element 3504 to power the card 104, such as a small cell battery LR44. The bottom of the power element 3504 is securely attached to the coating 3502 and contacts the power connection indicia 3510B. In some embodiments, one end of a conductive spring jaw 3508 contacts the top of power element 3504 and the other end of conductive spring jaw 3508 is connected to indicate power connection 3510A.

In some embodiments, the power on indicia 3510A and 3510B are printed in conductive ink or etched into the coating 3502. The power on indicia

ΊΛ / t / ZUZU / UUU / JO

106 Power 3510A electrically connects power element 3504 via conductive spring jaw 3508 to ground connections 3414 on contact plates 108. Power connection cue 3510B electrically connects power element 3504 to the power input of the contact plate. card 3412 on contact plates 108 on smart card 104. The circuit closure includes a pull tab 3506 made of non-conductive material temporarily positioned between the power element 3504 and the conductive spring jaw 3508 to interrupt the power circuit. When the user removes pull tab 3506 out of spring jaw 3508, the power circuit source is completed and power is supplied to card 104. In some embodiments, status indicators 308 can be used to signal to the user that power is present and / or that the enrollment process can begin.

In some embodiments, coating 3502 can be coated with conductive material. In such embodiments, power connection indicia 3510A, 3510B are absent. Instead, cover 3502 can be profiled such that cover 3502 mates with ground connections 3414 on contact plates 108 and with contact power input from card 3412 on contact plates 108 on smart card. 104 and the terminals of the power element do not conductively engage with any other part of the contact plate 108.

In some embodiments, the overlay 3502 may be part of the data entry device that extends over the fingerprint sensor 102. The data entry keys and associated key indicia can be printed and / or engraved on the overlay 3502 and coupled to detection area 102 in a similar manner as described in FIG. 34A and 34E to allow the user to enter data. In other embodiments, the overlay 3502 may comprise a portion that covers the fingerprint sensor 102 installed on the smart card 104, and further comprises data entry keys associated with (for example coupled to) the spatially distinct detection areas on the detection area 106 of the fingerprint sensor where the data entry keys are located in the detection area, as shown in FIG. 3B, or where the data entry keys are located remotely from the detection area 106 as shown in FIG. 13. In both of these scenarios, the portion of the skin 3502 that covers the fingerprint sensor 102 may be removable from the section of the skin that contains the power source connected to the power inputs of the smart card. For example, the overlay 3502 may be in two parts, or is perforated, or the overlay has two layers - one on top of the other - where the section containing the data entry keys is the uppermost. Thus, after the user has entered data using the data entry keys, the fingerprint sensor 102 can be revealed to complete the enrollment, without interrupting the power supply to the card 104. When the

ΊΛ / t / ZUZU / UUU / JO

107 registration is complete, the remaining portion of the 3502 coating can be removed.

In some embodiments, the overlay 3502 may comprise one or more LEDs or other status indicators (eg visual, audible, tactile indicators) used to indicate status to the user during enrollment in a situation where there are no status indicators on the screen itself. smart card, or where the status indicators on the smart card are inappropriate. In such embodiments, a component on smart card 104, such as the fingerprint sensor, secure element module, or other processing circuitry that monitors the status of the enrollment process and modulates a power line on card 104 in a known way, depending on the status of the registration process. Overlay 3502 may further comprise a sensing circuit configured to detect power line modulation and activate the one or more LEDs accordingly to indicate the correct status of the enrollment process.

In an alternative embodiment of FIGS. 34A to 34F and FIG. 35, the circuit breaker may comprise a switch or button instead of the collapsible cover section of FIGS. 34A to 34F or the pull tab of FIG. 35, thus enabling the user to complete the power circuit by applying the switch or button.

In an alternative embodiment of FIGS. 34A to 34F and FIG. 35, the coating 3402, 3502 contacts the data input and output contacts on the card contact plate 108 in addition to the power input and ground contacts. This can enable overlay 3402, 3502 to provide communication channels to and from items on card 104, such as the secure item module or the biometric sensor. In some embodiments, a wireless transceiver (eg Bluetooth, WiFi, NFC) mounted to the coating 3402, 3502 and connected to the data input / output of the contact plates of the card 108 can allow the elements on the card 104 to connect. wirelessly with each other to devices such as a mobile phone, laptop, ATM, card reader, or PC. In some embodiments, the overlay 3402, 3502 can harvest wireless signal energy to power the card 104 in addition to using the wireless connection to provide a communication channel. In such embodiments, the energy harvesting coating 3402, 3502 can temporarily convert a contact card to a contactless card.

In some embodiments, a cable plug (for example USB) mounted to the jacket 3402, 3502 and connected to the data inputs / outputs of the contact plates of the card 108 can allow the elements on the card 104 to be connected via a cable. to other devices such as a mobile phone, laptop, ATM, card reader, or PC. In some embodiments, the jacket 3402, 3502 may also receive power from the wire to power the card by further using the wire connection to provide a channel of

ΊΛ / t / ZUZU / UUU / JO

108 communication.

In some embodiments, the coating 3402, 3502 may make contact with the data input and output contacts on the card contact plate 108 in addition to the power and ground input contacts, in such embodiments, the coating 3402, 3502 may provide status indications to the user regarding items on card 104 for, such as the secure item module, the biometric sensor, and external devices connected to card 104. For example, LEDs, alarms, or a small LCD display mounted on the 3402, 3502 overlay and connected to the data input / outputs of the contact plate of the card 108 can indicate commands, responses, status information, data or user instructions.

FIG. 36 is a flow chart illustrating one embodiment of a simple, cost-effective method 3600 for enrolling a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a smart card, requiring entry of activation data (i.e., an activation code) before enrolling the fingerprint template.

At step 3602, a data entry device, such as the overlay described in FIGS. 34A through 34E, it is temporarily connected to a biometrics enabled device, such as a fingerprint enabled smart card. In some embodiments, a unique code, such as an activation code, can be stored in a secure memory of the smart card and encrypted in a secure location during the smart card manufacturing process. In some embodiments, the fingerprint sensor on the smart card can be calibrated during the manufacturing process and set to data entry mode before the smart card is sent to the user.

At step 3604, the card provider provides the smart card and data entry device with an integral power source to the user. For example, the card provider may provide the smart card and data entry device with the integral power source to the user by mail, courier, or directly to a bank or retail store. In some embodiments, the card and the data entry device can be packaged so that the power circuit cannot be accidentally completed during transit.

In step 3606, the user follows instructions to obtain an activation code from the card provider. In some modalities, the instructions to obtain the activation code can be received with the card. For example, the user may be required to call a number, or the data entry device may have a QR® code that the user can scan with a smartphone, or the user can enter your online banking site or

ΊΛ / t / ZUZU / UUUr

109 mobile application and indicate that you want to receive an activation code by SMS. Other security mechanisms for obtaining the activation code may be available in alternative modes. In some embodiments, a six-digit activation code provides the user with an appropriate level of security. The security level can be increased or decreased by varying the number of digits required, depending on the requirements of the card provider.

In step 3608, the user connects the smart card to the power source upon completion of the power circuit. For example, the power circuit can be completed by folding a section of the data entry device to make the conductive contact pads meet or by removing a pull tab that separates the power source from the smart card. Consequently, the card receives power from the power source, and a status indicator on the smart card (for example an LED) can indicate to the user that the smart card is ready.

At step 3610, the user enters the activation code by sequentially touching the data entry keys of the data entry device in a sequence corresponding to the activation code. In some modes, the status indicator can indicate to the user that the entered code is correct or incorrect. As described herein, if the entered code is incorrect, the user can make a predetermined number of additional attempts before the smart card permanently locks the user. For example, the user can get three attempts to correctly enter the code. In some modalities, if the number of unsuccessful attempts reaches the limit or the activation code is not entered before a preset time has passed, the smart card blocks the user.

At step 3612, if the activation code has been entered correctly, the user can now initiate fingerprint enrollment (enrollment mode) without removing the data entry device from the card. The smart card must remain connected to the power source throughout the entire enrollment process. In some embodiments, the status indicator can indicate to the user when an image is acceptable, for example, by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED. that blinks many times. The status indicator can indicate to the user when enough acceptable images have been collected for a fingerprint template, for example by the LED that is illuminated for a longer period, such as 10 or more seconds. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

ΊΛ / t / ZUZU / UUU / JO

110 or insufficient input to the fingerprint sensor for the purposes of gathering enough acceptable images for a fingerprint template. In such modes, the fingerprint sensor can enter a power saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

At step 3614, the user removes the data entry device from the smart card. In some embodiments, the data template can be discarded. The user can optionally also remove the data entry device after successful enrollment, possibly after additional data entry.

Consequently, the user has now successfully enrolled a fingerprint on the smart card through the simple, cost-effective 3600 method and can use the smart card in the normal way to pay for items, but now requires fingerprint verification. to use the smart card. In some embodiments, multiple users can enroll a fingerprint on the smart card, or one user can enroll multiple fingers on the smart card, using the above 3600 method. In such embodiments, the card can be programmed with multiple activation codes that are provided to each user. For each 3600 method, a new activation code is required and entered to enroll a new user / finger, which is made convenient by the fact that the data entry overlay was not removed during the previous fingerprint enrollment.

FIG. 37 is a flow chart illustrating one embodiment of a simple, cost-effective method 3700 for enrolling a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a smart card, without requiring entry of activation data (i.e. an activation code) before enrolling the fingerprint template.

At step 3702, a fingerprint enabled smart card is manufactured. A

ΊΛ / t / ZUZU / UUU / JO

111 data entry device, such as the overlay described in FIGS. 34A to 34E, it can be temporarily connected to the smart card. In some embodiments, the card provider can optionally set the smart card status to inactive to prevent unauthorized use before the intended user can enroll a fingerprint template and contacts the card provider to activate the card.

At step 3704, the card vendor provides the smart card and data entry device with an integral power source to the user. For example, the card provider may provide the smart card and data entry device with the integral power source to the user by mail, courier, or directly to a bank or retail store. In some embodiments, the card and the data entry device can be packaged so that the power circuit cannot be accidentally completed during transit.

At step 3706, the user connects the smart card to the power source upon completion of the power circuit. For example, the power circuit can be completed by folding the data entry device so that the conductive contact plates line up or by removing a pull tab that separates the power source from the smart card. Consequently, connecting the smart card to the power source does nothing but provide power to the electrical components of the smart card - for example LEDs, logic elements, sensor elements, etc. -, and the power source is unable to transmit data to or from the smart card.

At step 3708, one or more trigger events are detected that result in the fingerprint sensor being put into enrollment mode. An example trigger event may be based on a timer or counter not expiring. For example, in some embodiments, the triggering event may be to detect that the timer or counter has not expired. In such embodiments, a user can enroll a biometric template within a certain time after the fingerprint sensor is put into enrollment mode. In other embodiments, the triggering event may be to detect that the age of the smart card is under a certain age limit that is tracked, for example, by the timer or counter. In some embodiments, the counter can be incremented each time a biometric template has been successfully enrolled or whenever the smart card was used. In such embodiments, the triggering event may be to detect that the counter has not exceeded a predetermined threshold (eg, a predetermined number of biometric template enrollments or card uses).

ΊΛ / t / ZUZU / UUUZ JO

112 software or hardware component can be the triggering event. In such embodiments, the hardware or software component error would have to be a recoverable error (eg a minor error, a transient event, or a technical failure). Thus, the detection of a recoverable error that prevents completion of the enrollment process could cause the sensor to enter enrollment mode. In such embodiments, a non-recoverable error that occurs during enrollment (eg, a component on the card fails) might not initiate or constitute a trigger event.

Other example trigger events include detection of a flag set the last time the card was inserted into a card reader (for example a flag set when the card is inserted into a card reader that transmits data to or from the card and that instructs the card to enter enrollment mode the next time the card is connected to power), the lack of a fingerprint template enrolled on the card is detected, or it is detected that power has been supplied to the card. Some additional examples of a trigger event may include the detection that the card has been inserted into a power source that is connected only to the power contacts on the card and not to the data transmission contacts. In some embodiments, other events or a combination of such events may comprise trigger events. The trigger event can be detected by the fingerprint sensor, by another component on the card (for example the secure element module) or the trigger event can be detected as a result of the fingerprint sensor and another component on the card that interact, for example a handshake. In some embodiments, if a component other than the fingerprint sensor detects the trigger event, the component can signal the fingerprint sensor to enter enrollment mode.

In some embodiments, the enrollment mode can be triggered, but the user may not complete the enrollment. That is, the fingerprint sensor may be in the enrollment mode, but the user does not provide any input or insufficient input to the fingerprint sensor for the purposes of gathering enough acceptable images for a fingerprint template. In such modes, the fingerprint sensor can enter a power saving sleep mode, also referred to as a finger standby mode, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modalities, any acceptable images captured before the fingerprint sensor enters the power saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the sensor

ΊΛ / t / ZUZU / UUU / JO

113 fingerprint enters the power saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

The card remains in enrollment mode until disconnected from the power source or until registration is complete. If the card is disconnected from the power source before enrollment is complete, the process can move back to step 3706, in which an appropriate trigger event can result in the fingerprint sensor being returned to mode. of inscription. In some embodiments, the user may be required to take some action, such as, for example, contacting the card provider or obtaining a new card. In such modalities, the user can enable the new card to be put into enrollment mode.

In some embodiments, the card receives power from the power source, and a status indicator on the smart card (for example an LED) can indicate to the user that the one or more power transmission contacts of the power source are on. connected to the power source (that is, the card is powered on), the fingerprint sensor is in enrollment mode, and the smart card is ready for you to start enrollment.

At step 3710, the user can now begin enrolling a fingerprint. The fingerprint can be enrolled by storing a fingerprint template derived from one or more fingerprint images generated by placing a finger on the fingerprint sensor. The smart card must remain connected to the power source throughout the entire enrollment process. In some embodiments, the smart card can be disconnected from the power source during the enrollment process. In such modes, the fingerprint sensor enrollment mode is automatically disabled. In some embodiments, reconnecting the smart card to the power source moves the process back to step 3706, where an appropriate trigger event will result in the fingerprint sensor being returned to enrollment mode. The enrollment process is complete when a sufficient fingerprint template is acquired and stored in the fingerprint sensor (eg as described in previously incorporated US Patent No. 9,684,813). Once the enrollment process is complete, the enrollment mode on the fingerprint sensor is permanently disabled. In some embodiments, once the enrollment process is complete, the enrollment mode on the fingerprint sensor is disabled until a fresh trigger event occurs. In some embodiments, the status indicator can provide an indication to the user when an image is acceptable, for example by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example by the LED flashing many times. Status indicator can indicate to user when enough images have been collected

ΊΛ / t / ZUZU / UUU / JO

114 acceptable for the fingerprint template and confirming that the enrollment step was completed successfully, for example by the LED lighting for a longer period, such as 10 or more seconds. In other embodiments, more than one LED may blink different colors to communicate the various indications described herein. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

At step 3712, the user removes the data entry device from the smart card. In some embodiments, the data entry device can be scrapped. In some embodiments, the user can remove the data entry device after successful enrollment, possibly after additional data entry.

In some embodiments, the card provider may set the card's status to inactive at step 3702. In such embodiments, the user must activate the card before attempting to use it at step 3714, in which the user makes contact. with the card provider (for example by phone, app, internet, etc.) to activate the smart card. In some embodiments, the user must provide details of the user acceptable verification to the card provider to activate the smart card. If the user is verified, the card provider sets the card status as active in their systems. The user can now use the card in the normal way to pay for items, but now requiring fingerprint verification to use the smart card. If the user is not verified, the card remains inactive and cannot be used.

A device including a coating that provides only one power source, such as the 3402F coating described in FIG. 34F and coating 3502 described in FIG. 35 can be entered by other methods that do not require user input, such as method 2300 shown in FIG. 23A or method 2314 shown in FIG. 23B.

As stated above, it is preferable that the fingerprint template is of sufficient quality, otherwise the user may experience a high rejection rate or false acceptances. This can be a particular problem when the user is unfamiliar with the goal of the enrollment stage, which is to capture multiple boards, good quality images as much as possible of both the fingerprint and the finger. If the user does not know that the user needs to obtain images taken of all of the user's fingerprints, including the sides and tips as well as the central portion of the fingerprint, the user may be inclined to repeatedly present the same portion of their finger. during enrollment, thus restricting the coverage of the fingerprint template and increasing the chance of false rejection.

It has been observed that the pressure and the angle at which a user presents their fingerprint

115 digital during enrollment is different from how your finger presents in daily use of your device. For example, the thumb can be enrolled in a smart card by repeatedly touching the fingerprint sensor when the smart card is laid flat. This will likely result in a fingerprint template being captured from the central thumbprint. However, when the smart card is actually being used, the user is likely to either hold the card in a pliers holder or insert it into the base of a Point of Sale (PoS) device in the case of a card. contact smart card, or hold the card over the PoS until the transaction is recorded in the case of a contactless smart card. In such contact and non-contact use cases, the impression of the tip of the thumb typically contacts the sensor when the smart card is in use. That is, a part of the thumb, for example the tip of the thumb, was probably lost in the fingerprint template during an enrollment made on a card that was laid flat through the entire enrollment process.

The above issues relate to difficulties that occur during the enrollment process on a limited device. An additional complication for a limited input / feedback device is that once the enrollment process is complete, if the user begins using their device and later finds that their fingerprint is not being reliably recognized, the user may not have a mechanism whereby you can re-enroll your finger to create a better fingerprint template and thus improve your user experience. Reenrollment on a limited device may be deliberately prohibited for security reasons, for example, the device manufacturer may not want to create a backdoor by allowing the fingerprint template to be changed by an unauthorized user, or it may simply not be handy for the user to interact with the device to put it back into enrollment mode and thus re-enroll their finger. In such situations, it becomes critical for the user experience that their finger is properly enrolled the first time because there is no second chance to change the fingerprint template. A smart card is a good example of a limited input / feedback device where a user might be unlikely to get the opportunity to re-enroll their finger if the first fingerprint template is not suitable.

In some devices, such as laptop computers or door entry systems, the fingerprint sensors may be surrounded by finger guides, such as beveled peripheral edges, to force the user to place their finger on the sensor in an optimal manner. These guides are permanent features of the device. That is, the guides are present when the user enrolls their finger and remains in place when the user is actively using their device. Such guides are designed primarily to ensure that the most useful part of the finger is inscribed for user verification (i.e. the center of the fingerprint) and

ΊΛ / t / ZUZU / UUU / JO

116 second, to increase the chances that the same part of the finger that was initially inscribed will be placed on the sensor during daily use. An example is described in European Patent Application No. EP 1812890, entitled Finger Guiding Device, the description of which is incorporated by reference in its entirety. For many devices however, it is not practical to change the form factor to have permanent finger guides in place, or it is undesirable in relation to design aesthetics to have such permanent finger guides. For example, it might be unacceptable for a smart card to have a permanent finger guide in place as the card might no longer fit in standard ATM machines, bags or wallets.

Another existing solution to the problems listed above is to guide the user to present different parts of their finger during enrollment using a graphic in a user interface on the device. Such a solution is described in US Patent No. 9,715,616, entitled Fingerprint Detection and Enrollment, the disclosure of which is incorporated by reference in its entirety. In some embodiments, the graph in the user interface shows a representation of a fingerprint that gradually becomes shaded as left, right, top, bottom, etc. images are captured. fingerprint, thus motivating the user to present different parts of their finger during the enrollment process. This solution, however, is limiting in the sense that it is difficult to explain to the user how a captured image of a fingerprint relates to any particular part of their finger when the device containing a fingerprint sensor does not have, or has a limited user interface.

Another existing solution is to use dynamic enrollment. More specifically, a method in which a fingerprint template is assembled and adapted over time to account for changes in the shape of a finger is presented in everyday use. That is, the fingerprint template can actively evolve as new captured images are added to it through daily use. An example of a dynamic registration method is presented in US Patent Application Publication No. US2014 / 0003681, entitled Zero Registration, the description of which is incorporated by reference in its entirety. However, dynamic enrollment may be prohibited for certain devices that contain fingerprint sensors due to security concerns that an unauthorized user could successfully enroll their finger by repeatedly presenting their finger so that the fingerprint template evolves to the point. on which your finger will be accepted.

As explained herein, another existing solution for enrolling a fingerprint in a limited input / feedback device requires the user to visit a secure location, such as a bank, where the user will perform the enrollment procedure. Such a solution, however, includes several disadvantages particularly related to user inconvenience and possible security breaches as already discussed herein.

Rather than having a user attend a secure location, alternative solutions have been proposed to enroll a finger in a limited input / feedback device containing a fingerprint sensor. However, such workarounds require that the device containing the fingerprint sensor be connected to a second connected device, for example a smartphone or computer terminal, so that instructions and feedback can be given to the user during enrollment. via a user interface of the second connected device. This method is far from ideal because not only does it require the user to have easy access to a second device, but also because it requires the device manufacturer and the fingerprint sensor manufacturer to be able to communicate across a myriad of devices. secondary. This method also presents significant security concerns because the user is enrolling their fingerprint on one device that is actively connecting to a second connected device that can be connected to other networks.

The modalities described herein provide systems, devices and methods of enrollment of a fingerprint on a device with interfaces or status indicators limited to non-users that can be performed by the user in their own home, without the need to visit a location. safe to enroll and without requiring the user to connect their card to another connected device such as a smartphone. Systems, devices, and methods complementary to those described herein improve the quality and coverage of the enrolled fingerprint template, thereby increasing security and improving the accuracy of fingerprint matching for the limited device.

Such complementary systems, devices and methods include a guide for placing the finger (where the definition of finger includes a thumb) on a fingerprint sensor during finger enrollment. The guide is profiled to increase the likelihood that images of many diverse portions of the fingerprint will be obtained when enrolling using a fingerprint sensor with a small area compared to the area of a typical finger or thumbprint. in particular by capturing images of the longitudinal segment of the fingerprint that runs from the tip of the finger to the knuckle, which is the richest in minutiae of the fingerprint, leading to a more comprehensive enrolled fingerprint template (or set of fingerprint templates) and therefore more reliable for user verification. In some embodiments, the guide is removably attached to the surface of the device in operative proximity to the sensor and is removed after enrollment is complete. The guide is typically not used during regular operation (eg user verification) with the fingerprint sensor.

FIGS. 38-40 show an example of a removable finger guide, in various embodiments the guide 3802 comprises a base sheet 3804 that conforms to the surface of the host device 104 containing the fingerprint sensor 102. In FIGS. 38 to 40 the

118 host device 104 shown is a flat smart card, then the base sheet 3804 is flat, however, for example, if the host device surface was curved (for example a control lever on a cart), then the base sheet 3804 could be appropriately profiled to make a press fit with the surface of the device 104 surrounding the fingerprint sensor 102. Finger guide 3802 can be made of any suitable material, such as molded plastic. Base sheet 3804 is removably bonded to the surface, for example, held in place with repositionable adhesives such as those provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik. In some embodiments, finger guide 3802 can be slid over host device 104, clamped over host device 104, or folded over host device 104 instead of adhering to the surface of device 104. If host device 104 is metallic or includes metal components, the finger guide 3802 may be magnetic and thus stick to the surface of the device 104. In some embodiments, the base sheet 3804 may extend over the edges of the host device 104. As shown in FIG. 38, base sheet 3804 comprises cutout 3810 to reveal detection area 106 of fingerprint sensor 102 when finger guide 9802 is placed in operative proximity to fingerprint sensor 102.

Finger guide 3802 further comprises one or more channels used to capture various finger images from the user's fingerprint. In FIG. 38, finger guide 3802 has three channels: A channel 3806A, B channel 3806B, and C channel 3806C. With finger guide 3802 secured (for example temporarily) to host device 104 in operative proximity to fingerprint sensor 102, each of channels 3806A-C is configured to position a finger placed therein in a unique orientation relative to to the fingerprint sensor 102. In some embodiments, channels 3806A-C can be configured with curved walls and have a width corresponding to a typical finger width.

In some embodiments, the base sheet 3804 has a raised section 3808, parallel to one side of the detection area 106, in which the C-channel 3806C is formed as shown in FIG. 38. Raised section 3808 is used to point the user's finger upward to channel the user's fingertip to touch the sensor instead of the center of the fingerprint. In some embodiments, the raised section 3808 can be a ramp with the lowest point of the ramp located at an edge of the fingerprint sensor 102. In some embodiments, the raised section 3808 can be ergonomically profiled to motivate the user to rest their finger on it. In some embodiments, a front detent 3812 may be present on the opposite side of the sensor in raised section 3808 to stop sliding off of the fingertip sensor.

FIG. 39, channels 3806A-C can be indicated by markings 3902 (for example arrows or lines) on base sheet 3804. For example, base sheet 3804 can be marked with indicia, such as lines, curves, arrows, etc. ., to indicate how far the finger should be inserted into each channel 3806A-C so that the fingerprint touches the detection area of the fingerprint sensor and does not extend too far or fall too short. In some embodiments, channels 3806A-C can be ergonomically profiled. In some embodiments, channels 3806A-C may have side walls to guide the finger in each channel 3806A-C.

FIG. 40 is a top perspective view of the finger guide with directional finger placement arrows superimposed thereon in accordance with some embodiments. In FIG. 40, three channels are shown, indicated by channels A 3806A, B 3806B, and C 3806C. Arrows A and B in FIG. 40 show the direction of a finger approaching the detection area 106 via channels A 3806A and B 3806B, respectively. Arrow C in FIG. 40 shows the direction of a finger approaching detection area 106 via raised section 3808, ie, C channel 3806C.

FIG. 41 shows a top perspective view of a finger guide 4102 according to some embodiments. As shown in FIG. 41, finger guide 4102 has a T profile while comprising the same essential features as finger guide 3802 described in FIGS. 38 to 40. For example, finger guide 4102 comprises a base sheet 3804, channels A 3806A, B 3806B, and C 3806C, a front detent 3812, a raised section 3808, and a cutout 3810 to expose the detection area 106 of the sensor. fingerprint.

Channels 3806A-C of finger guide 3802, 4102 can be the width of a human finger. In some embodiments, differently sized finger guides 3802, 4102 could be made available to fit a variety of fingers, eg, small, medium, or large, rather than one size to fit all. The 3810 cutout needs to fit around the detection area 106 of the fingerprint sensor, typically an 8x8mm, 9x9mm or 9.5x9.5mm square, however other sensor sizes or profiles may be ordered.

In some embodiments, finger guide 3802, 4102 can be decorated with indicia. For example, photographs of fingers, or images of fingers can be inscribed on the surface of the finger guide 3802, 4102 so that it is clear to a user where to put their fingers.

An enrollment method that makes use of a temporary, inexpensive off-grid power source is described herein. Specific examples include the card holder / power supply 920 shown in FIGS. 9E to 9G. In some embodiments, the finger guide 3802, 4102 described in FIGS. 38-41 can be placed over the sensor at the same time that the device is powered using the power sources described herein.

In the embodiment described in relation to FIGS. 47A to 47H, a smart card 104 is the device that contains the fingerprint sensor 102. However, the application of finger guide 4702 and overlay 4704, 4732 is not restricted to a smart card and can be used for any device that contains a fingerprint sensor in alternate modes. In some embodiments, smart card 104 comprises fingerprint sensor 102 with a detection area 106, possibly LEDs or other status indicators, and contact plates 108 that provide contacts for an external power source.

In some embodiments, the coating 4704, 4732 comprises a thin material, for example a film that conforms to a surface of the host device when secured thereto. In some embodiments, the overlay 4704, 4732 is an adhesively backed label or film temporarily and removably placed on the card 104. In some embodiments, repositionable adhesives provided by companies such as 3M, Krylon, Franklin Adhesives and Polymers, and Bostik can be applied to the coating 4704, 4732 to be temporarily placed on the portion of the card 104 including the contact plates 108. In other embodiments, the temporary covering 4704, 4732 can be slipped over the device, clamped over the device, or folded over the device instead of adhering to the surface of the device. In some embodiments, the coating can be magnetic and stick to the surface of the device if the device is metal.

FIGS. 47A to 47B show top perspective views of the finger guide 4702 incorporated into the data entry device in the form of an overlay 4704 integrating a power source with a host device (eg, smart card 104) disposed below the overlay. 4704. A cut 4713 in the coating 4704 and a cut 4715 in the finger guide 4702 expose a portion of the detection area 106 while another portion of the detection area 106 remains covered. As described above, the covered portion of the detection area 106 refers to the X portion and the exposed portion of the detection area 106 refers to the Y portion. In some embodiments, overlay 4704 comprises data entry keys 4706A-F on an upper surface of overlay 4704. In such embodiments, overlay 4704 comprises corresponding connection indicia 4708A-F on a bottom surface of overlay 4704. connection 4708A-F electrically couples each data entry key with a spatially distinct associated portion of the detection area 106.

In some embodiments, the coating 4704 may comprise a suitable power element 4726 (shown only in FIGS. 47D to 47F) to power board 104 and sensor 102, such as an LR44 small cell battery. In such embodiments, power element 4726 is securely attached to shroud 4704 and makes electrical contact with a power element contact plate 4730 (shown in phantom lines in FIG. 47F) of shroud 4704. For example, a A battery terminal can contact the contact plate of the 4730 power element. A 4722B power connection cue connects ground to the 4730 power element contact plate and a 4722A power connection cue connects the contact's power input to a 4724 conductive contact (shown only in FIGS. 47D at 47F). In some embodiments, the 4722A, 4722B power connection indicia, the card contacts (for example, contact power input and ground), 4730 power element contact plate, and 4724 conductive contact are etched or printed on metal, metallic paint, conductive ink, conductive polymer, or any conductive coating on the underside of the 4704 coating. Any appropriate routing arrangement for the 4722A, 4722B power connection indicia on the lower surface of the 4704 overlay is possible with the requirement that the routing of the 4722A, 4722B power connection indicia must avoid the exposed portion of the detection area. 106 and connection indicia 4708A-F for data entry keys 4706A-F.

Finger guide 4702 may be connected to or integrally formed with liner 4704. In the illustrated embodiment, finger guide 4702 includes three finger guide channels: an A channel flange 4712, a C channel flange 4714, a B channel flange (or raised section) 4716 with a beveled leading edge 4718, a front detent 4720 having a curved contour to accommodate a curved tip of a finger positioned in the B channel 4716, and the cutout 4715 through which a sensing portion 106 of the inserted card 104 is exposed. Finger guide 4702 could be made of any suitable material, such as molded plastic.

In various embodiments, finger guide 4702 further comprises a lever 4710 configured to enable a user to selectively close a power circuit between power element 4726 and the terminals of the electronic device to enable transmission of power between the power element. 4726 and the electronic device. The lever 4710 and the circuit breaker will be described in greater detail in FIGS. 47C to 47F.

FIG. 47C shows a top view of finger guide 4702 incorporated into shroud 4704 with an enlarged view of lever 4710. In some embodiments, the

In such embodiments, finger guide 4704 may comprise a latch or detent configured to capture lever 4710 when pushed down by the user and hold lever 4710 in the pushed down position. In some embodiments, lever 4710 can be an on-off rocker switch or a dome, plunger, or bulb switch.

FIGS. 47D to 47F show various bottom views of the finger guide 4702 incorporated into the data entry device in the form of an overlay 4704 integrating a power source with a host device (eg smart card 104) disposed below the overlay 4704 As shown in FIGS. 47D to 47F, power element 4726 is attached to the bottom surface of shroud 4704 on the contact plate of power element 4730 (shown only in FIG. 47F). In some embodiments, the energy element 4726 is attached to the bottom surface of the liner 4704 underlying the finger guide 4702. In such embodiments, the finger guide 4702 provides a stiffening effect for the liner 4704 and further supports the energy element. 4726.

Conductive contact 4724 is positioned underlying lever 4710 (not shown in FIGS. 47D through 47F). In some embodiments, a portion of the coating 4704 is cut so that the coating 4704 is surrounding the conductive contact 4724. In some embodiments, a conductive spring jaw may contact a terminal of the power element 4726. Consequently, when the user pushes lever 4710 down, conductive contact 4724 is also pushed down and contacts conductive spring jaw 4728 extending from power element 4726, thereby closing the power circuit between power element 4726 and the power transmission contacts or terminals of the electronic device (eg smart card 104) to enable transmission of power between power element 4726 and the electronic device. Once the user has completed an enrollment process using the fingerprint sensor 102, the configuration of the finger guide 4702 incorporated into the overlay 4704 makes it convenient for the user to hold a portion of the finger guide 4702 that extends outside. from smart card 104 and remove finger guide 4702 and overlay 4704 from smart card 104.

As described above, a portion of the cover 4732 covers the contact plate 108 of the device 104. The cover 4704 comprises power connection indicia 4722A, 4722B and card contacts that make contact with the power plates (eg power terminals ) from contact plate 108 when coating 4732 is applied to card 104. In some embodiments, the card contacts include a contact 4734 power input and a ground 4736. In some embodiments, the cover 4732 may comprise a suitable power element, as previously described in FIGS. 47A to 47F, to power card 104 and sensor 102, such as an LR44 small cell battery. In such embodiments, the power element is securely attached to a bottom surface of the cover 4732 and makes electrical contact with a power element contact plate of the cover 4732. For example, a terminal of a battery can contact the battery. power element contact plate. A 4722B power connection cue connects ground to the power element contact plate and a 4722A power connection cue connects the contact power input to a conductive contact. In some embodiments, the 4722A, 4722B power connection indicia, the card contacts (for example the 4734 contact power input and 4736 ground), the power element contact plate, and the conductive contact are etched or printed on metal, metallic paint, conductive ink, conductive polymer, or any conductive coating on the bottom side of the 4732 coating.

Finger guide 4702 may be connected to or integrally formed with liner 4732. As previously described in FIGS. 47A to 47F, finger guide 4702 comprises lever 4710 configured to enable a user to selectively close a power circuit between the power element and the terminals of the electronic device (eg, smart card 104) to enable transmission of energy between the energy element and the electronic device. Once the user has completed an enrollment process using the fingerprint sensor 102, the configuration of the finger guide 4702 incorporated in the overlay 4732 makes it convenient for the user to hold a portion of the finger guide 4732 that extends outside. from smart card 104 and remove finger guide 4702 and cover 4732 from smart card 104. Removing finger guide 4702 and cover 4732 from smart card 104 disconnects the power transmission between the power element and smart card 104.

In other embodiments, finger guide 4702 comprising switch 4738 may be combined with a data input device in the form of a cover that integrates a power element as previously described in FIGS. 47A to 47F.

FIGS. 471 through 47J show various top views of one embodiment of finger guide 4702 comprising switch 4738 configured to enable a user to selectively open and close a power circuit between power element 4726 (shown in FIGS. 47J through FIGS. 47K) and the terminals of the electronic device (eg smart card 104) to enable and disable the transmission of power between the power element and the electronic device. As shown in FIG. 471, switch 4738 may be configured to be movable in direction A to close the power circuit, thereby initiating the transmission of power between the power element and the electronic device in accordance with some embodiments. The switch 4738 can also be configured to be movable in direction B to open the power circuit, thereby terminating the transmission of power between the power element and the electronic device. The initiation and termination of energy transmission between the energy element and the electronic device will be described in more detail below in FIGS. 47K to 47L.

In some embodiments, the switch 4738 comprises a top surface 4744, two side walls 4740A-B (one side wall 4740A shown in FIGS. 471 through 47J and the other side wall 4740B shown in FIGS. 47K through 47L), and a rear wall 4746. In such embodiments, finger guide 4702 comprises two slot cuts 4742A-B, in which the two side walls 4740A-B of switch 4738 are located, respectively. Consequently, the slot cuts 4742A-B allow a user to move the switch 4738 back and forth in directions A and B, as shown in FIG. 471. In some embodiments, the top surface 4744 comprises a raised section (eg, a handle) 4750 configured to assist a user in sliding the switch back and forth in directions A and B.

FIG. 47K shows a bottom perspective view of one embodiment of finger guide 4702 comprising switch 4738. For purposes of explanation, FIG. 47K shows 4738 switch with 4740A side wall removed. As described above, power element 4726 is attached to the bottom surface of liner 4748 underlying finger guide 4702. As shown in FIG. 47K, a 4728 conductive spring jaw comprising a 4752 round conductive head at a distal end extending from the

127 power element 4726. Cover 4748 comprises a conductive contact 4724 positioned above head 4752. Switch 4738 further comprises a lower base 4746 which comprises a stepped surface. In some embodiments, the stepped surface comprises two passages 4754A-B, each including a smooth curved surface. In such embodiments, each surface of passageways 4754A-B is configured to receive rounded head 4752. As shown in FIG. 47K, the step 4754A closest to the power element 4726 is smaller than the other step 4754B. Consequently, when switch 4738 is pushed back in direction B, underpass 4754A receives head 4752. The underpass 4754A is configured to receive the head 4752 so that the head 4752 does not make contact with the conductive contact 4724, thus opening the power circuit between the power element 4726 and the terminals of the electronic device (e.g. smart card 104) to terminate or disable power transmission between the power element and the electronic device.

FIG. 47L shows a cross-sectional side view of one embodiment of finger guide 4702 comprising switch 4738 along line LL in FIG. 471. As shown in FIG. 47L, switch 4738 is slideable in direction B according to some modes. In such embodiments, the lower step 4754A moves towards the direction of the power element and the upper step 4754B moves in the anterior position of the lower step 4754A. Consequently, the round conductive head 4752 is pushed up and received by the curved upper surface of the upper step 4754B, as shown by the arrow on the dotted line in FIG. 47L. The upper step 4754B is configured to receive the head 4752 so that the head 4752 makes contact with the conductive contact 4724, thereby closing the power circuit between the power element 4726 and the terminals of the electronic device (for example the card smart 104) to initiate or enable transmission of power between the power element 4726 and the electronic device.

In some embodiments, the user can move switch 4738 in direction B to disable transmission between power element 4726 and electronic device (eg, smart card 104). In such embodiments, the step closest to the power element 4726 may be higher than the other step of the lower base 4746. Consequently, moving switch 4738 in direction A could enable transmission between power element 4726 and the electronic device.

In some embodiments, the round conductive head 4752 can be separated from the conductive spring jaw 4728 and attached to the conductive contact 4724. In such embodiments, the distal end of the conductive spring jaw 4728 can be pushed up and down by the movement of switch 4738, as described above, to initiate and

ΊΛ / t / ZUZU / UUUZ

128 terminate the transmission between the power element 4726 and the electronic device (eg, smart card 104).

As shown in FIGS. 471 through 47L, switch 4738 enables a user to selectively initiate and terminate the transmission of power between power element 4726 and the terminals of the electronic device (eg, smart card 104). The minimum number of components of the 4738 switch, as described above, enables reduction in manufacturing cost.

In alternative embodiments to coating 4702 shown in FIGS. 47A to 47L and having a 4710 lever or 4738 switch, the coating lacks a finger guide.

FIGS. 48A and 48B are left and right partial perspective views of an alternate configuration of finger guide 4800. Finger guide 4800 comprises a first channel 4802 (channel A), a second channel 4804 (channel B), and a third channel 4806 (channel C). Appreciate that channels A, B, and C are marked differently in the manner described above as the particular labeling, if any, is not critical. Finger guide 4800 further comprises a cutout 4850 for the fingerprint sensor and a front detent 4808 located across cutout 4850 of channel 4804.

In some embodiments, channel 4802 provides a generally flat (ie, parallel to the surface of the sensor) focus for a finger positioned thereon. In some embodiments, channel 4804 may be raised above the plane of the exposed sensor surface at cutout 4850 and has a flat top portion and a stepped ramp 4854 (eg, approximately 45 degrees) that extends into cutout 4850. In some embodiments, channel 4806 has a gentle slope (eg, approximately 10-15 degrees) that extends downward from cut-off 4850.

The flat focus of the first channel 4802, the gentle ramp of channel 4804, and the steep ramps of channel 4806 could be on either side of the sensor (i.e., 4850 cutoff), in any order, but the arrangement shown is ideal for a sensor. fingerprint positioned above a long central axis and near the short right-hand edge of a smart card, as illustrated in Figure 1. For example, on a typical bank card, the sensor can be placed in this position so as not to interfere with the secure element module that is typically near the short left-hand edge of a smart card, or with the symbols printed or embossed. and / or a magnetic strip on the smart card, both of which run parallel to, but positioned below, the long central axis of the card.

When the card is held, it is more natural to provide a tip touch on the second channel 4804 because channel 4804 is closer to the short edge of the card, as shown in FIG. 49A.

ΊΛ / t / ZUZU / UUUr

129

On channel 4806, the user has to reach more card material compared to channel 4802. The gentle slope of channel 4806 is complementary to the resulting position of the thumb, which means that a different part of the surface is more likely finger is imaged on channel 4802, as shown in FIG. 49B.

On channel 4802, the user holds the card on the long side closest to the sensor, as shown in FIG. 49C.

In some embodiments, the finger guides, and, if applicable, the card holder frames, of FIGS. 38 to 48B are made of inexpensive materials that can be safely disposed of, for example, plastic, cardboard, rubber, or foam. The materials can be lightweight so that the finger guide can be delivered to the user by mail or courier at low cost. In some embodiments, the base sheet, raised section (s), and channel (s) of the finger guide may be molded into a single unit, or they may be separate parts.

Finger guides such as those shown in FIGS. 39 to 48B require the user to place a finger on the sensing surface at positions that are separated from each other by angles in a plane parallel to the sensing surface and at positions that are elevated relative to the sensing surface. Thus, such guides provide a three-dimensional variation of finger positions during enrollment. The benefits of such three-dimensional variation are conceptually shown in FIGS. 50, 51, and 52.

FIG. 50 shows the novice registration (that is, without a guide on how to register) according to some modalities. Without guidance, the user typically puts his finger 5006 up and down again in the same or similar places along the longitudinal axis 5002. The user does not rotate his finger relative to the sensor, and so the captured images 5004 are not very different. each. Also, none of the fingers are captured. This has a particularly adverse impact on the user verification that results if the device containing the fingerprint sensor is a smart card. Since smart cards are thin and light, they will most likely be held between the thumb and finger with the tip of the thumb on the sensor, so it is important to enroll the tip in the fingerprint template.

FIG. 51 shows a two-dimensional angled inscription according to some modalities. In angled enrollment, the user is encouraged to rotate his finger 5006 with respect to the longitudinal axis of finger 5002. For example, the user can rotate his finger 5006 by +/- 45 degrees as well as 0 degrees with respect to the longitudinal axis of finger 5002. Consequently, more of the sides of the fingerprint can be captured as images 5004 for the fingerprint template, but less of the longitudinal segment of the fingerprint is captured since the user probably will not rotate their finger 5006 as much. Since the inscription shown in FIG. 51 is two-dimensional, that is, flat, it is unlikely to capture images of the area of the

ΊΛ / t / ZUZU / UUU / JO

130 fingertip.

FIG. 52 shows a three-dimensional inscription according to some modalities. In three-dimensional inscription, the user is prompted to rotate his finger 5006 with respect to the longitudinal axis of finger 5002 and use a channel having a ramp. For example, the user can rotate their finger 5006 by +/- 90 degrees as well as 0 degrees and use a channel that has an incline ramp and / or a channel that has a gentle ramp. For three-dimensional inscription, the user has to physically rotate the device containing the sensor to insert his finger 5006 into the channel, thereby increasing the chances of extending the coverage of the fingerprint template because his finger 5006 will almost certainly be placed. in a different location than before (eg 180 degrees between channels A and C in FIGS. 48A and 48B). Having the channels with both sloping and gentle ramps means that the coverage of the fingerprint template is extended to include the fingertip. Consequently, the result of that three-dimensional inscription is a larger portion of the longitudinal segment of the fingerprint captured as images 5004 for the fingerprint template compared to other inscription techniques.

In some alternate finger guide modalities, two or more different finger channels may not be located in fixed positions with respect to the sensing surface as in the finger guides described herein, but can be moved with respect to the surface. detection device to selectively place one of the channels in operative proximity to the detection surface.

FIG. 53A is a top plan view of an alternate finger guide 5302 whereby two or more cuts 5304A-C and associated finger guide channels 5306A-B move linearly with respect to sensing surface 106 to selectively align the cut 5304A-C with the sensing surface 106 and placing the associated finger guide channel 5306A-B in operative proximity to the sensing surface in accordance with some embodiments. Finger guide 5302 is temporarily attached, adhered, or otherwise attached to a smart card 104. The smart card can be inserted into a power sleeve 5308 or other power source, such as, for example power source 902. shown in FIG. 9A, the power source 910 shown in FIG. 9D, the power source 920 shown in FIG. 9F, or any other suitable power source to which card 104 can be attached. In some embodiments, finger guide 5302 and power source 5308 could also be connected together or otherwise manufactured as a single integral unit.

As shown in FIG. 53A, finger guide 5302 includes a panel 5310 having two or more cutouts 5304A-C that are movably or otherwise slidably attached to rails 5312, or other structures allowing linear translation of panel 5310, attached to the card. In the illustrated embodiment, the panel includes three cuts A 5304A, B 5304B, C 5304C that can be

ΊΛ / t / ZUZU / UUU / JO

131 selectively aligned with the detection surface 106 of the card fingerprint sensor by moving panel 5310 relative to rails 5312, and each cut 5304A-C has a different finger channel configuration. For example, cut A of finger 5304A has a flat focus whereby a finger placed thereon is generally parallel to the surface of the sensing surface of fingerprint sensor 106. Cut B 5304B includes a gentle ramp 5306A whereby a finger is positioned there and is oriented at an elevation angle of, for example, 10-15 ° relative to sensing surface 106. In some embodiments, a front detent ( not shown in FIG 53A) cut-out 5304B may be provided adjacent to the opposite side of ramp 5306A. Cut C 5304C may have an inclined ramp 306B whereby the finger is oriented at an elevation angle of, for example, about 45 ° relative to sensing surface 106. In some embodiments, a front detent (not shown in FIG. 53A) can be provided adjacent cutout 5304C on the opposite side of ramp 5306B.

Panel 5310 is movable relative to rails 5312, which may be connected to card 104 so that any of the A, B, or C cuts 5304A-C may be aligned with sensing surface 106. In the embodiment shown in FIG. 53A, detection area 106 is shown through cut C 5304C, which lines up with detection area 106. In some embodiments, retainers or other similar features may be provided to releasably secure panel 5310 relative to guide rails 5312 to resist, but not prevent, translation of panel 5310 relative to rails 5312 so that panel 5310 will contain a selected linear position. In one embodiment as shown in FIG. 53B, the bottom side of the panel 5310 has spaced bolts 5314 while the top side of the rails 5312 has soft teeth 5316 so that the panel 5310 can be slid until a cut 5304A-B aligns with the sensing surface 106. The panel 5310 remains in selected position during finger enrollment through aligned cutout. In some embodiments, the user has to push or pull the panel 5310 hard enough to overcome the resistance of the bolts 5314 joining the teeth 5316 to align a different cut with the sensing surface 106.

In the illustrated embodiment shown in FIG. 53A, panel 5310 is movable relative to guide rails 5312 and card 104 in a direction parallel to the long side of card 104. In some embodiments, panel 5310 may be movable relative to guide rails 5312 and card 104 in a direction parallel to the short side of card 104.

FIG. 54 is a top plan view of an alternate finger guide 5402 whereby two or more cuts 5402A-C and associated finger guide channels 5306A-B are rotatably movable relative to sensing surface 106 to selectively align the cut. with the sensing surface 106 and placing the associated finger guide channel 5306A-B in operative proximity to the sensing surface 106 in accordance with some embodiments. The card

132 Smart 104 can be inserted into a power sleeve 5308 or other power source, such as, for example, power source 902 shown in FIG. 9A, the power source 910 shown in FIG. 9D, the power source 920 shown in FIG. 9F, or any other suitable power source to which the card can be attached. In some embodiments, rotary finger guide 5402 and power source 5308 could also be connected together or otherwise manufactured as a single integral unit.

In the illustrated embodiment shown in FIG. 54, the rotary finger guide 5402 is in the form of a rotary disk or element having three cuts A 5306A, B 5306B, C 5306C. The rotating element can rotate about its center to selectively position one of the cutouts A 5306A, B 5306B, or C 5306C in alignment with the sensor. In the illustrated embodiment shown in FIG. 54, cut C 5306C is aligned with sensing surface 106.

FIGS. 55, 56, and 57 illustrate various components of the rotary finger guide 5402 shown in FIG. 54. FIG. 55 shows an embodiment of the base 5500 of the rotary finger guide 5402 that can be removably attached to the smart card 104 or any other fingerprint sensor enabled by the device. For example, the 5500 base can be removably attached by fasteners, adhesive, or the like. The base of the rotating element 5500 has a shaft 5502 in its center, a base cutout 5504, and a spindle 5506 for a position selector arm. Base 5500 is secured to smart card 104 with base cutout 5504 aligned with the fingerprint sensor.

FIG. 56 shows an upper portion 5600 of rotary finger guide 5402 according to some embodiments. The A, B, and C cuts 5402A-C are formed in the upper portion 5600. In some embodiments, the upper portion 5600 may include a number of position selector posts 5602A-C. The upper portion 5600 may further include a center knob 5604 for rotating the upper portion. Alternatively, instead of knob 5604, the user could rotate the upper portion, ie, the rotatable element, 5600 by its outer peripheral edge.

FIG. 57 is a side view of a position selector 5702 of the rotary finger guide 5402 according to some embodiments. In some embodiments, position selector 5702 comprises a flexible arm 5704 projecting radially from spindle 5506 of base 5500.

The upper portion 5600 is mounted on the shaft 5502 of the base 5500 so that the upper portion 5600 can rotate about the shaft 5502 when the user turns the knob 5604 or rotates the upper portion about its edge. The position selector arm 5704 is positioned so that the arm 5704 contacts the position selector posts 5602A-C of the upper portion 5600 to thereby contain the upper portion 5600 in a position that aligns one of the cuts A 5402A, B 5402B, C 5402C with 5504 base cutout and sensor. To rotate the portion

ΊΛ / t / ZUZU / UUUr JO

133 upper 5600 and repositioning guide 5402, the user applies torque to upper portion 5600 to overcome elasticity of the position selector arm and move position selection post 5602AC past position selector arm 5704 and rotate upper portion 5600 to align the next 5402A-C cutout with the 5504 base cutout and sensor.

In the illustrated embodiment shown in FIG. 56, the upper portion 5600 includes three cuts A 5402A, B 5402B, C 5402C that can be selectively aligned with the sensing surface 106 of the card fingerprint sensor by rotating the upper portion 5600, i.e. the rotating element, with relative to the 5500 base, and each cut has a different finger channel configuration 5306A-B. For example, finger cut A 5402A has a flat focus whereby a finger placed thereon is generally parallel to the surface of the fingerprint sensor sensing surface. In some embodiments, cut B 5402B includes a gentle ramp 5306A whereby a finger placed thereon is oriented at an elevation angle of, for example, 10-15 ° relative to sensing surface 106. In some embodiments, a front detent can be provided adjacent the cutout on the opposite side of the ramp. The C cut 5402C may have an inclined ramp 5306B whereby the finger is oriented at an elevation angle of, for example, approximately 45 ° relative to the sensing surface 106. In some embodiments, a front detent may be provided adjacent to the cut on the opposite side of the ramp. In the illustrated embodiment shown in FIG. 56, a front detent 5606 is provided on the opposite side of the inclined ramp 5306B. However, a front detent can also be provided on the opposite side of the gentle ramp 5306A in some embodiments.

In some embodiments, more than three cuts may be provided in the rotary finger guide 5402 each with different guide angles of raised finger guide channel sections (also referred to as ramps) and / or with different profiled channel walls of finger.

FIG. 58 is a flowchart illustrating one embodiment of a simple cost-effective method 5800 for enrolling a biometric template, such as a fingerprint template, in a device that has limited ability to provide feedback to the user, such as a smart card. and using a power source (such as the power source described above in FIG. 9F) and separate finger guide (such as the finger guide described above in FIGS. 38 to 41), or alternatively using a power source with the integrated finger guide (such as the power source with the integrated finger guide described above in FIGS. 42 to 47L).

In step 5802, a fingerprint enabled smart card is manufactured. In some embodiments, the card provider can set the smart card status to inactive to prevent unauthorized use before the intended user can enroll a fingerprint template and contacts the card provider to activate the card.

ΊΛ / t / ZUZU / UUUZ

134

In step 5804, the card provider provides the smart card and a simple low-cost power source and temporary finger guide to the user, eg, sent by mail or courier or given by a bank or retail store. The power source could be battery powered, powered by mains (eg via a USB connector), or solar powered. The finger guide can be separate from the power source, or integrated into the power source. In another embodiment, if the smart card contains an on-board power source, such as a solar cell, an external power source is not required.

In step 5806, the user positions the finger guide around the detection area of the fingerprint sensor. In some embodiments, the smart card can be delivered to the user with the finger guide already positioned around the sensor. The user then connects the smart card to the power source, for example by inserting the card into a power source housing that has contacts for connecting one or more power transmission contacts of the smart card to the power source without Connect any data transmission contacts from the smart card to a device configured to transmit data to or receive data from the card. Consequently, in such embodiments, connecting the smart card to the power source does nothing but provide power to the electrical components of the smart card - for example, LEDs, logic elements, sensor elements, etc. - and the power source. Power is unable to transmit data to or from the smart card. In other embodiments, the finger guide can be used in conjunction with a power source including means for transmitting data to or from the smart card. If the finger guide and the power source are a single integrated device, then positioning the finger guide relative to the fingerprint sensor and connecting the smart card to the power source comprise a single step of inserting the smart card or docking otherwise operatively the smart card to the embedded device.

In some embodiments, the smart card and power source can be delivered to the user with the smart card already inserted into the power source. In such embodiments, a battery connection tab is inserted between the power source and the smart card to keep a connection power disconnected. The user can pull out the battery connection tab to connect the power source to the smart card.

In step 5808, one or more trigger events are detected that result in the fingerprint sensor being put into enrollment mode. An example trigger event may be based on a timer or counter not expiring. For example, in some embodiments, the triggering event may be to detect that the timer or counter has not expired. In such embodiments, a user can enroll a biometric template within a certain time after the fingerprint sensor is put into enrollment mode. In other embodiments, the triggering event may be to detect that the smart card age is under a certain limit of

ΊΛ / t / ZUZU / UUU / JO

135 antiquity that is tracked, for example, by the stopwatch or the counter. In some embodiments, the counter can be incremented each time a biometric template has been successfully enrolled or whenever the smart card was used. In such embodiments, the triggering event may be to detect that the counter has not exceeded a predetermined threshold (eg, a predetermined number of biometric template enrollments or card uses).

Other example trigger events include detection of a flag set the last time the card was inserted into a card reader (for example a flag set when the card is inserted into a card reader that transmits data to or from the card and that instructs the card to enter enrollment mode the next time the card is connected to power), the lack of a fingerprint template enrolled on the card is detected, it is detected that power has been supplied to the card, or the entry of a PIN code (for example, via a data entry template coupled to the power source as described above. Yet another triggering event may be the detection that the card has been inserted into a power source that is connected only to the power contacts on the card and not to the data transmission contacts. Other events, or combinations of events, can be trigger events. The trigger event can be detected by the fingerprint sensor, or by another component on the card (for example the secure element module) or it can be detected as a result of the fingerprint sensor and another component on the card that interacts, for example a handshake. If a component other than the fingerprint sensor detects the trigger event, that component can signal the fingerprint sensor to enter enrollment mode.

ΊΛ / t / ZUZU / UUU / JO

136 Power-saving sleep, also referred to as a finger standby, to avoid draining the power source. For example, after the fingerprint sensor enters enrollment mode and does not receive any input from the user for a predetermined period of time, the fingerprint sensor enters power-saving sleep mode and waits for the touch of a user to activate and finish the registration process. In some modes, any acceptable images captured before the fingerprint sensor enters the power-saving sleep mode are saved so that the enrollment process continues where the user left off. In some modes, smart card components, such as the secure element module, can enter a sleep mode when the fingerprint sensor enters a power-saving sleep mode. Similarly, smart card components can be activated when the fingerprint sensor wakes up from the power-saving sleep mode and the enrollment process ends.

The card remains in enrollment mode until disconnected from the power source or until registration is complete. If the card is disconnected from the power source prior to completing enrollment, the process may move back to step 5808, whereupon an appropriate trigger event will result in the sensor being returned to enrollment mode, or alternatively the user may be required to take some action, such as contacting the card provider or obtaining a new card, to enable the card to be put into enrollment mode.

The card receives power from the power source, and a status indicator on the smart card (for example an LED) indicates to the user that the one or more power transmission contacts of the power source are connected to the power source. (that is, the card is powered on), the fingerprint sensor is in enrollment mode, and the smart card is ready for enrollment to begin.

At step 5810, the user can now begin to enroll a fingerprint with the aid of the finger guide. Step 5810 is described in greater detail in FIG. 59. The fingerprint is enrolled by storing a fingerprint template derived from one or more fingerprint images generated by placing a finger on the fingerprint sensor. The smart card must remain connected to the power source throughout the entire enrollment process. In the event that the smart card is disconnected from the power source during the enrollment process, the enrollment mode on the fingerprint sensor is automatically disabled. In some embodiments, reconnecting the smart card to the power source moves the process back to step 5808, whereby an appropriate trigger event will result in the sensor being returned to enrollment mode. The enrollment process is complete when a sufficient fingerprint template is purchased and stored on the fingerprint sensor (for

ΊΛ / t / ZUZU / UUU / JO

137 example one described in US Patent No. 9,684,813 incorporated above). Once the enrollment process is complete, the enrollment mode on the fingerprint sensor is disabled permanently or alternately, until a fresh trigger event occurs. In some embodiments, the status indicator provides an indication to the user when an image is acceptable, for example by an LED that lights up for a few seconds, and can indicate when an image is not acceptable, for example, by the LED that blinks many times. The status indicator can indicate to the user when enough acceptable images for the fingerprint template have been collected and confirm that the enrollment step was completed successfully, for example by the LED lighting for a longer period, such as 10 or more seconds. In some embodiments, more than one LED can blink in different colors to communicate the various indications described above. In some embodiments, a flexible presentation such as an OLED panel can be used to provide textual feedback during the enrollment process.

In step 5812, the user removes the smart card from the power source, thereby disconnecting the one or more power transmission contacts of the smart card from the power source. In some embodiments, the power source can be scrapped. The user can also now remove the finger guide (if it is not integrated into the power supply) and can dispose of it.

If the card provider sets the card status to inactive in step 5802, then the user must activate the card before attempting to use it.In step 5814, the user contacts the card provider (for example by phone , application, internet, etc.) to activate the smart card. The user must provide acceptable user verification details to the card provider to activate the smart card. If the user is verified, the card provider sets the card status as active in their systems. The user can now use the card in the normal way to pay for items, but now requiring fingerprint verification to use the smart card. If the user is not verified, the card remains inactive and cannot be used.

As discussed above, in step 5810 of FIG. 58, the user enrolls his finger in the host device with the help of the finger guide. FIG. 59 interrupts step 5810 of FIG. 58 as a 5900 method to provide more detail as to how to assist the finger guide in the enrollment process.

As described above, in step 5808, a trigger event puts the fingerprint sensor in enrollment mode. Once the fingerprint sensor is put into enrollment mode, the process can start method 5900 with step 5810A according to some modalities. In step 5810A, the user places their finger in channel A of the finger guide and

ΊΛ / t / ZUZU / UUU / JO

138 Touch the fingerprint sensor detection area. The sensor captures an image of the finger and optionally signals the user if the captured image is acceptable via a status indicator. The user repeatedly lifts and touches the sensor with the same finger via channel A until a total of w acceptable images (touches) have been captured, where w can range from 1-5, for example, 2. In some embodiments, the user can lift and touch the sensor with the same finger any number of times before the total of w acceptable images (touches) have been captured and move to step 5810B or step 5810C before returning to step 5810A. to complete the total of w acceptable images.

In step 5810B, the user places the same finger in channel B of the finger guide and touches the detection area of the fingerprint sensor. The sensor captures an image of the finger and optionally signals the user if the captured image is acceptable via a status indicator. The user repeatedly lifts and touches the sensor with the same finger via channel B until a total of x acceptable images have been captured, where x can vary between 1-5, for example 2. In some embodiments, the user can lift and touch the sensor with the same finger any number of times before the total of x acceptable images (touches) has been captured and moves to step 5810A or step 5810C before returning to step 5810B to complete the total of x acceptable images.

In step 5810C, the user places the same finger on channel C and touches the detection area of the fingerprint sensor. The sensor captures an image of the finger and optionally signals the user if the captured image is acceptable via a status indicator. The user repeatedly lifts and touches the sensor with the same finger via channel C until a total of y acceptable images have been captured, where y can range from 1-5, for example, 2. In some embodiments, the user can lift and touch the sensor with the same finger any number of times before the total of y acceptable images (touches) has been captured and moves to step 5810A or step 5810B before returning to step 5810B to complete the total of and acceptable images.

At step 5810D, the registration is complete and the process continues to step 5812 described above.

Steps 5810A-C can be performed in any order. For example, method 5900 can start with any of steps 5810A-C.

In some embodiments, the total number of acceptable images (touches) that need to be captured for a sufficient fingerprint template can be the sum of x + y + z. In such embodiments, the user can place the same finger in a channel, for example channel A, B, or C, of the finger guide and repeatedly lift and touch the sensor with the same finger via the same channel until the total number of acceptable images, for example x + y + z, is captured. By lA / t / ZUZU / UUU l

139 For example, if method 5900 has started with step 5810B, the user can repeatedly lift and touch the sensor with the same finger via channel B until the total number of acceptable images is captured. Once the total number of acceptable images is reached in step 5810B, the enrollment is complete and the process continues to step 5812.

In some embodiments, the finger guide may comprise one or more status indicators, such as LEDs, and a control processor coupled to the one or more status indicators and configured to assist the user during the enrollment process described in the 5900 method. The one or more status indicators may provide an indication to the user as to which channel of the finger guide to place the same finger. With reference to the finger guide (such as the finger guide described above in FIGS. 38-41), or alternatively the power source with the integrated finger guide (such as the power source with the integrated finger guide described above in FIGS. 42 to 47L), each of the finger guide channels may comprise one or more status indicators. Consequently, the control processor can be configured to indicate to the user through the one or more status indicators on each channel on which channel the user should put the same finger. For example, one or more status indicators on a C channel wing may instruct the user to place the same finger on C channel. As a further example, after the user places the same finger on channel C, one or more status indicators on a wing of channel B may instruct the user to subsequently place the same finger on channel B. In this way, the Control processor can guide the user through the enrollment process by indicating in which channels of the finger guide to place the same finger.

In some embodiments, capacitive strips can be implemented around the edges of each side of the sensing area corresponding to each channel. For example, a capacitive strip can be placed around one edge of the detection area corresponding to channel A. Similarly, a capacitive strip can be placed around the remaining two edges of the detection area corresponding to channel B and channel C. In such embodiments, the fingerprint sensor can be configured to recognize that the user has placed a finger in a certain channel when the finger contacts, or comes into close proximity, the corresponding capacitive strip. For example, the fingerprint sensor can recognize that the user has placed a finger in channel C when the finger makes contact with, or comes into close proximity to, the capacitive strip placed around the edge of the detection area corresponding to channel C.

In an alternative embodiment, such capacitive strips can be implemented on each side of the finger cut guide corresponding to each channel. For example, a capacitive strip can be located on a lower surface of one side of the cutout corresponding to channel A. Similarly, a capacitive strip can be located on a lower surface of the two remaining sides of the cutout corresponding to channel B and channel C. In such modalities, each strip

ΊΛ / t / ZUZU / UUUZ JO

140 Capacitive may slightly overlap with a corresponding edge of the detection area when the finger guide is placed over the fingerprint sensor so that the cut exposes the detection area. Accordingly, the fingerprint sensor can be configured to recognize that the user has placed a finger in a certain channel when the finger makes contact with, or comes into close proximity to, the corresponding capacitive strip. For example, the fingerprint sensor can recognize that the user has placed a finger in the C channel when the finger makes contact, or comes into close proximity to the capacitive strip located on the lower surface of one side of the cut corresponding to the channel C.

In some embodiments, the finger guide may have only a single channel. Consequently, the method 5900 of FIG. 59 may include only step 5810A. In such embodiments, the process continues to step 5812 after step 5810A.

In some embodiments, the finger guide may have only two channels. Consequently, the method 5900 of FIG. 59 may include only two steps, for example step 5810A and step 5810B. In such embodiments, the process continues to step 5812 then to step 5810B.

In some embodiments, the finger guide can be removed after step 5810C and the user can then touch the detection area of the fingerprint sensor with the same finger with no guide present. In such embodiments, the 5900 method may include an additional step, in which the sensor captures an image of the finger and optionally signals to the user if the captured image is acceptable via a status indicator. The user repeatedly lifts and touches the sensor with the same finger until a total of z acceptable images have been captured, where z can range from 1-5, for example 2. The process then continues to step 4812.

The process described in method 5900 of FIG. 59 is easily extended if the finger guide has more than three channels.

The sensitivity of fingerprint sensor performance to poor enrollment is governed to some degree by how the biometric matching algorithm, operating in conjunction with the particular sensor hardware, is designed to operate. For example, some biometric algorithms perform fine-tuning, while others employ peak flow analysis. Fingerprint templates can be created in different ways, such as by ligation, or image filtering and classification. Some biometric algorithms are agnostic to the rotation of the finger in relation to the orientation of the sensor while others are not. It is beneficial if the manufacturer of the fingerprint sensor device understands how the fingerprint templates are generated and how their matching algorithms operate. This information, taken with knowledge of how the end user holds and operates the device in daily use, enables the identification of parts of the fingerprint, including the peripheral portions, which should be inscribed to see reliable verification of the user at all the cases

ΊΛ / t / ZUZU / UUU / JO

141 of use, when a particular sensor design is executing a particular biometric algorithm.

For some fingerprint sensor and biometric algorithm combinations, one way to maximize coverage of the minutiae-rich longitudinal segment is to use a finger guide with three channels, where channel A is offset from channel C by -m degrees and channel B is offset from channel C by + n degrees, assuming the center of channel C aligns with the center of the fingerprint sensor detection area, Measured in the same plane as the plane of the fingerprint sensor detection area, "m" and "n" are in the range 0 - 180 degrees and in some modes m and n are 90 degrees, although m and n do not need to be The same.

Also, when viewed in cross section, channel C is elevated from the plane of the fingerprint sensor's detection area (and then the plane of channels A and B) by and the elevation angle of + p degrees, assuming that the center of channel C is aligned with the center of the fingerprint sensor detection area, measured in cross section to the plane of the fingerprint sensor detection area. The elevation angle "p" is in the range 0-90 degrees and in various modes, p is between 15 and 45 degrees.

Various forms of angled channels are shown in FIGS. 60A to 60D. In the embodiment shown in FIG. 60A, channel A is offset from channel C by -90 degrees and channel B is offset from channel C by +90 degrees, while the center of channel C aligns with the center of the detection area 106 of the fingerprint sensor . As shown in FIG. 60A, channel C is raised out of the plane of detection area 106 by the elevation angle of +40 degrees. In the embodiment shown in FIG. 60B, channel A is offset from channel C by -45 degrees and channel B is offset from channel C by +45 degrees, while the center of channel C aligns with the center of the detection area 106 of the fingerprint sensor . As shown in FIG. 60B, channel C is raised out of the plane of detection area 106 by the elevation angle of +20 degrees. In the embodiment shown in FIG. 60C, channel A is offset from channel C by -135 degrees and channel B is offset from channel C by +135 degrees, while the center of channel C aligns with the center of the detection area 106 of the fingerprint sensor . As shown in FIG. 60C, channel C is raised out of the plane of detection area 106 by the elevation angle of +20 degrees. In some modalities, the biometric algorithm is rotation agnostic. In such embodiments, FIGS. 60B and 60C will produce similar images. FIG. 60D shows an example of a finger guide configuration with eight channels, seven of which lie in the same plane as fingerprint detection area 106 and one of which, i.e. channel C, is angular via section raised to fingertip over detection area. In an alternative embodiment described above in FIGS. 48A and 48B, more than one channel can be angular using more than one raised section in the base sheet to the fingertip in different orientations in the detection area.

lA / t / ¿UZU / UUU l JO

142

FIGS. 61A through 61C show example cross-sectional profiles of the raised section and illustrate how the C channel angle p is achieved when the finger is tapped when hitting the upper edge of the raised section closer to the detection area 106. As shown in FIGS. 61A to 61C, various regular and irregular profiles of the raised section are possible and these figures show only a few examples. In some embodiments, the raised section can be aligned with the edge of the fingerprint sensor, or it can be placed behind the edge of the sensor. In FIG. 61A, raised section 6102A is placed behind an edge of detection area 106. In FIG. 61B, an edge of the raised section 6102B forms a curved profile of the channel wall. In FIG. 61C, the raised section is placed at an edge of the detection area 106.

FIGS. 62A, 62B, 62C schematically depict finger contact with a fingerprint sensor using the fingerprint guide of FIG. 48A and 48B according to some modalities. FIG. 62A shows a top plan view of finger contact with detection area 106, where the position of the finger is represented by arrows A, B, and C. As shown in FIG. 62A, the finger positions A and B are separated by degrees (eg 90 degrees), and the finger positions B and C are m degrees apart (eg 90 degrees). FIG. 62B shows a side view of a finger contacting detection area 106 while positioned in channel B, whereby the finger is oriented at an elevation angle of p degrees (eg, approximately 45 degrees). FIG. 62C shows a side view of a finger contacting the sensing area while positioned in channel C, whereby the finger is oriented at an elevation angle of # degrees (eg about 10-15 degrees).

FIG. 63 is a flow chart showing a process 6300 for reenrollment of a biometric sensor, such as a fingerprint sensor, based on a trigger event that causes the sensor to go into reenrollment mode. A process for initially enrolling a biometric such as a fingerprint whereby an trigger event causes the sensor, such as a fingerprint sensor, to enter the enrollment mode is described above and is shown in FIG. 23B. Re-enrollment may be required when the initial enrollment was unsuccessful or only partially successful, resulting in a biometric template unable to provide reliable verification. In some modalities, a card provider may prohibit re-enrollment entirely for security reasons.

In step 6302 of process 6300, the user connects the biometric sensor enabled device, such as a fingerprint sensor enabled smart card, for which a biometric template has already been enrolled or an enrollment has been attempted, to a source of power, including any of the power sources described above (with or without a finger guide). At step 6304, a trigger event results in the sensor being put into reenrollment mode. Exemplary trigger events for reenrollment at step 6304 may include lA / t / ZUZU / UUU l JO

143 insert the card into the power source, detect a specific time of connection of the card to the power source (for example second, third, etc. connection of the smart card to the power source), detection of an existing biometric template already enrolled, detection of a certain card inserted into a certain power source (i.e. unknown pair), a user is verified by matching finger against the existing biometric template, entry of an activation code (i.e. PIN code) (for example via a data entry template coupled to the power source as described above), a signal from the secure element module or other card component, counter for the number of uses below a certain threshold (i.e. the user is not allowed to re-enroll if the card is not new, or relatively new), the age of the card below a certain threshold (for example the memory on the card stores a timestamp of when the card was first used in a PoS and a timestamp of when the card was used last if the difference between time stamps is less than a certain threshold, re-enrollment is triggered), maximum number of allowable re-enrollments not yet reached, user interactions with the sensor, placing or removing a coating on the biometric sensor, placing or removing a data entry device in the form of a coating or sleeve on the biometric sensor, activation of an input mechanism, or any combination of the foregoing. Instead of using a power source, a card provider can trigger re-enrollment if the card is placed in a secure terminal, for example ATM, PoS or bank terminal. A user ID could then be verified via fingerprint and / or activation code (PIN) or other forms of ID as a trigger for re-enrollment.

At step 6306, the user enrolls a fingerprint, for example in accordance with any of the enrollment procedures described above.

At step 6308, if reenrollment is successful, the existing stored biometric template is replaced in the memory of the host device with a new enrolled biometric template. If reenrollment is not successful, then a new biometric template is not stored, and the existing stored biometric template is retained in the memory of the host device. Alternatively, in step 6308, if the reenrollment is successful, the existing biometric template is modified based on the biometric images acquired during the reenrollment procedure. For example, the existing biometric template could be augmented or amplified with additional images, rather than completely replacing it. As part of the process to augment or amplify an existing biometric template, a requirement could be to establish that new images can be enrolled only to the existing biometric template if they are similar to images in the existing biometric template (also referred to as a limited form of dynamic inscription.).

In step 6310, the user can remove the smart card from the source of

ΊΛ / t / ZUZU / UUU / JO

144 power after fingerprint enrollment.

In some cases, it may be necessary or desirable to enroll a biometric template for each of more than two fingers. FIG. 64 shows a flow chart illustrating a 6400 process for enrolling a biometric template on a biometric sensor enabled host device, such as enrolling a fingerprint template on a fingerprint sensor enabled smart card, whereby after a Enrollment process, a determination is made as to whether an enrollment procedure should be repeated for a different finger. At step 6402, a fingerprint-enabled smart card is manufactured, and optionally, the manufacturer sets the status of the smart card to inactive. At step 6404, the smart card and a power source, for example a removable, temporary power source (with or without a finger guide) as described above, is shipped to the user. In step 6406, the user connects the smart card to the power source. At step 6408, a trigger event causes the fingerprint sensor to be put into an enrollment mode for a first finger. Exemplary trigger events may include events such as those described above, for example in relation to the process shown in FIG. 23B. At step 6410, the user enrolls a fingerprint and if the enrollment is successful, a fingerprint template for that finger is created in the memory of the host device. At step 6412, a trigger event occurs to determine whether the fingerprint sensor should be put into a repeat enrollment mode for another finger. The trigger event to repeat the enrollment in step 6412 could be: a signal from the secure element or other component of the smart card, detecting that the card remains in the power source for more than a predetermined number of seconds after the last fingerprint template was successfully enrolled, detecting that the existing number of fingerprint templates already enrolled has not yet reached the maximum, user data input (for example, user can hold down a finger long-term inscribed on the sensor or double tap on the sensor, the activation code input), place or remove a coating on the sensor, place or remove a data input device on the form of a coating or sleeve on the sensor, activating an input mechanism or any combination of the above. If it is determined in step 6412 that the sensor should be put into a repeat enrollment mode, the sensor returns to step 6410. If the trigger event does not occur such that the sensor is not put into repeat enrollment mode, in step 6414, after enrollment of the required fingers, the user removes the smart card from the power source. In an optional step 6416, the user contacts the smart card provider to activate the smart card.

A novel feature of the modalities described herein is the ability to use a fingerprint sensor in a position sensing mode in such a limited device.

ΊΛ / t / ZUZU / UUU / JO

145 like a smart card. The conventional use of a fingerprint sensor in position sensing mode has been reserved for smartphones, computers, and tablets.

Another novel feature of the modalities described herein are the different configurations of data entry devices, such as data entry devices in the form of coatings and frames, temporarily placed over the detection area of a fingerprint sensor. installed in a limited device to guide a user to spatially distinct control areas for control and data input for the device. Once the data entry device is removed, the fingerprint sensor operates as a verification method for authorized use of the device.

Another novel feature of the modalities described herein is the simple, cost-effective method of enrolling a fingerprint template in a limited device using the different configurations of data entry devices, such as the data entry device in the form of overlays and frames, temporarily placed over the detection area of a fingerprint sensor.

One of the significant advantages achieved by the modalities described herein is that the user's fingerprint data never leaves the smart card. The power source (also referred to as a non-data transmitting power source) simply provides power to operate the smart card and does not take part in the enrollment process to transmit data to or from the smart card. Another significant advantage provided by the embodiments described herein is that the fingerprint sensor can provide a mechanism for data entry and limited device control in addition to user verification.

The modalities described herein provide the user with a convenient method of enrolling a fingerprint while increasing security because the enrollment process can be performed at home and completely off-network. An added benefit is the convenience of the device process for enrolling fingerprint templates on devices with limited feedback / input capabilities.
