Battery pack for a mobile terminal

1. Technical Field

0001The present invention relates to a method for payment and recharging using a mobile terminal equipped with a UIM (user identification module) card. Particularly, the present invention is directed to a mobile terminal equipped with a UIM card containing finance information and a method using the same so that the UIM card containing a number of finance and authorization information can be attached to a mobile terminal and both online and offline payment and recharging service can be provided by making use of a local wireless communication module.

2. Background Art

0002In general, payment by an IC card (credit card, debit card, prepaid card, or traffic card) or recharging thereof can be processed only through a dedicated terminal. In case of online payment through the Internet, too, approval of payment can only be obtained by entering a card number and expiration date after purchasing goods at the corresponding shopping mall. A method utilizing a card, however, suffers from a problem that the card number can be exposed to others by, e.g., hacking because both card number and expiration date are entered at the time of payment for purchasing amount.

0003A system to resolve the aforementioned problem is disclosed in Korean Laid-Open Patent Application No. <patcit id="pcit0001" dnum="KR200037185"><text>2000-37185</text></patcit>. The disclosed system enables prepaid transactions by embedding an RF chip for a non-contact type prepaid card with an identification number into a mobile communications terminal, with which occasional inquiry into the balance of the prepaid card and recharging thereof are carried out through the Internet. The disclosed system has several advantages such that since a non-contact type RF chip and antenna coil are embedded into a mobile communications terminal, there is no need to carry a card; inquiry into the balance information stored in the RF memory chip can be carried out through a Web server as well as a service terminal; and even recharging can also be fulfilled through a Web server instead of visiting a recharging station for a prepaid card at each and every occasion. However, since said RF chip dose not record monetary information except for the card identification number and actual monetary information according to the card identification number is stored in a Web server, a terminal at a membership store should make a reference to the Web server for the balance information, after which subsequent transactions are conducted; accordingly, the disclosed system is not well suited for the application to a traffic card of a bus or a subway where prompt transactions are demanded. Moreover, the disclosed system is no more than a mobile phone equipped with a pre-existing RF card so that interactions with a mobile phone are not implemented; therefore, a user can only carry out simple functions of making a reference to the Web server for the inquiry into the balance information and recharging by using the card identification number given at the time of subscription or purchase of the mobile phone.

0004In Korean Laid-Open Patent Application No. <patcit id="pcit0002" dnum="KR199846928"><text>1998-46928</text></patcit>, an electronic purse card operating system is disclosed wherein, by embedding a combi-chip comprising a contact type and non-contact type smart card into a mobile device, functions of balance check, subtraction payment, and addition recharging are conducted by the contact type smart card, while balance check and subtraction payment are conducted by the non-contact type smart card. A recording area for electronic purse information of said two smart cards is synchronized so that identical electronic purse information is utilized, whereby convenience and promptness in usage and stability and security in data processing can be improved. However, the disclosed system also reveals a problem that since available money for payment is confined to the balance stored in the recording area of the combi-chip for electronic purse information, it can only be applied to a prepaid card; therefore, application areas are limited.

3. Disclosure of Invention

0005The object of the present invention to resolve said problem is to provide a mobile terminal equipped with a user identification module card containing finance information and a method using the same so that payment of finance information and recharging through wireless communication are enabled by storing various finance information into a detachable user identification module card.

0015<figref idref="f0001">FIG. 1</figref> is a block diagram illustrating a simplified structure of the entire system according to the present invention comprising a mobile terminal 10, a payment terminal 30, a card issuing company 40, a financial institution 50, a shopping mall 60, and a service providing system 70.

0016The said mobile terminal 10, equipped with an apparatus (slot) capable of installing and decrypting a user identification module (hereinafter, referred to as UIM) card 12 and a local area communication module capable of local area wireless communications, can make an access to the Internet and by using authorization information and finance information of said UIM card read out through wireless communications, carries out functions such as payment of purchased goods, recharging the balance of said UIM card, ticketing, and transaction particulars inquiry. In the memory of said UIM card 12 recorded are authorization information such as a mobile identification number, private identification number (hereinafter, referred to as PIN), and a certificate; and personal information such as a user name, address, and contact number; also stored are finance information of various IC cards (credit card, debit card, prepaid card, traffic card) . The UIM card 12 is equipped with a microprocessor and memories so that storing and updating finance information are possible. In the <figref idref="f0001">FIG. 1</figref>, for the purpose of brevity, constituting elements such as a mobile communications base station and a telephone exchange system of a mobile telecommunication company which appear prior to the Internet access have been omitted.

0017The said payment terminal 30 is similar to CAT (Credit Authorization Terminal) installed at a membership store and is equipped with a local area wireless communication module to communicate with said mobile terminal 10. The said payment terminal 30 is connected to a card issuing company 40 or a financial institution 50 through the Internet or VAN (Value Added Network) which is not shown in the drawing.

0018The said card issuing company 40 and financial institution 50 carry out the functions such as approval of payment for purchased goods and recharging the balance of a UIM card 12 using finance and authorization information stored in the UIM card 12.

0019The said shopping mall 60 is a merchandise sales system providing online purchase and payment and carries out different processes according to the information about payment means received from the user, i.e., finance information of a UIM card 12: authorization is received by a card issuer 40 in case of a credit card; approval of a transaction is confirmed by the corresponding financial institution 50 in case of a debit card; and in case of a prepaid card, the balance remained in the UIM card 12 is checked and if appropriate, the payment process is completed and purchased goods are shipped by using personal information read out and received from said UIM card 12.

0020The said service providing system 70 communicates with said mobile terminal 10 connected to the Internet 20 and provides various services in association with a card issuer 40, a financial institution 50, and a shopping mall 60 by making use of authorization information, personal information, and finance information of an inserted UIM card 12. The said service providing system 70 comprises a payment processing system 72 handling payment for purchased goods or services, a prepaid card recharging system 74 recharging the balance of a prepaid card of the UIM card 12, a ticket issuing system 76 allowing ticket reservation using finance information of the UIM card 12 and transmitting information about reserved tickets to said mobile terminal 10, and a traffic card issuing system 78 providing services intended for a traffic card for expressway, subway, or bus.

0021<figref idref="f0002">FIG. 2</figref> is a diagram illustrating a simplified structure of a mobile terminal according to the present invention. <figref idref="f0002">FIGS. 3</figref> and <figref idref="f0003">4</figref> are diagrams illustrating an embodiment of a payment system using a local area communication module according to the present invention.

0022A mobile terminal 10 according to the present invention, without modifying an ordinary mobile terminal, can detach, attach, and decrypt a UIM card 12 wherein authorization information, finance information, and personal information are stored. The mobile terminal 10 is equipped with a UIM card slot 102 through which data can be recorded into the UIM card and a local area communication module 105 capable of local area wireless communication with a payment terminal 30. The said local area communication module 105 can employ a communication system using RF, IrDA (Infrared Data Association), or Bluetooth. Payment, recharging, and ticket reservation through the Internet utilize existing communications part of the mobile terminal.

0023As shown in <figref idref="f0002">FIGS 3</figref> and <figref idref="f0003">4</figref>, payment is accomplished by communicating with a local area communication module 32 installed in a payment terminal 30. <figref idref="f0002">FIG. 3</figref> shows the payment terminal 30 installed at an ordinary store and <figref idref="f0003">FIG. 4</figref> shows the payment terminal installed at an entrance gate of a theater or a subway station.

0024<figref idref="f0004">FIG. 5</figref> is a flowchart illustrating a procedure to use various services using a mobile terminal according to the present invention.

0025First, a UIM card 12 is inserted into the UIM card slot 102 of a mobile terminal S100. After insertion of the UIM card 12, the mobile terminal 10 decides whether or not the UIM card 12 is recognizable and insertion has been correctly made; when it turns out to be incorrect, the mobile terminal generates a fault message notifying the user of a card insertion failure S102; otherwise, finance information, authentication information, and personal information stored in the memory of the UIM card 12 are read out S103. Next, a password is requested to verify whether or not he or she is a valid user and after the entrance of a password S104, a decision is made whether or not it is identical to the password read out from authorization information S105. When the entered password is not correct, a denial message is displayed S106 and re-entry of a password is requested to the user. In case of a correct password, a service menu is displayed and the user's selection for a service is awaited. The user selects a desired service from displayed menus such as payment S108, transaction particulars inquiry S109, prepaid card recharging S110, ticket issuing and using 5111, and traffic card issuing and using S112.

0026Hereinafter, each service will be described in more detail.

0027<figref idref="f0005 f0006 f0007">FIGS. 6 to 8</figref> are service flowcharts when a user selects the payment service from said service menus. It is assumed that steps prior to payment such as choosing particular goods to purchase and selecting a payment means have been completed.

0028<figref idref="f0005">FIG. 6</figref> is a flowchart illustrating a payment procedure using a credit card according to a first embodiment of the present invention.

0029When the payment processing system 72 of a service providing system sends a payment start instruction, the user enters purchasing information such as a shopping mall, purchasing list and purchased amount and carries out requisite operations for payment. At this time, purchasing information may be handled so that it can be automatically filled in at the shopping mall. After operations for payment have been accomplished by the user, credit card information and authorization information read out from the UIM card 12 through the S103 procedure described in <figref idref="f0004">FIG. 5</figref> are transmitted to the payment processing system 72. The payment processing system 72 requests a credit inquiry to a card issuer 40. If approval for card use is received according to the result of the credit inquiry, the payment processing system 72 makes a payment request and completes the payment process. After payment is completed and a confirmation message for payment is transmitted to the mobile terminal 10, the mobile terminal 10 displays the confirmation message for payment to the user and stores the payment particulars into the memory of the UIM card 12.

0030<figref idref="f0006">FIG. 7</figref> is a flowchart illustrating a payment procedure using a debit card according to a second embodiment of the present invention. <figref idref="f0007">Fig. 8</figref> is a flowchart illustrating a payment procedure using a prepaid card according to a third embodiment of the present invention.

0031As shown in <figref idref="f0005">FIG. 6</figref>, the user who received the payment start instruction from the payment processing system 72 enters purchasing information and carries out requisite operations for payment. Then, the mobile terminal 10 transmits debit card information and authorization information read out from the UIM card 12 to the payment processing system 72. The payment processing system 72 makes a registration inquiry and requests balance information to the corresponding financial institution 50; the payment processing system 72 compares the balance of the user's account of the corresponding financial institution 50 with the payment amount. If the account has an insufficient balance, the payment processing system 72 carries out a payment failure processing, whereas, if the balance is more than the payment amount, the payment processing system 72 requests a payment to the financial institution. After completion of the payment, the payment processing system 72 transmits a confirmation message for payment to the mobile terminal 10 so as to display the message to the user. The mobile terminal 10 stores payment particulars into the memory of the UIM card 12 after completion of the payment.

0032The payment procedure using a prepaid card is similar to said <figref idref="f0006">FIG. 7</figref>. It is different from that of <figref idref="f0006">FIG. 7</figref> in that balance information is not received from the financial institution 50, but balance information of a prepaid card in the UIM card is received directly from the mobile terminal 10; after completion of payment, the balance of the prepaid card in the UIM card 12 subtracted by as much as the payment amount is stored by the mobile terminal 10.

0033Prior to the aforementioned payment service, if a shopping mall employed a method to obviate the user's manual entrance of personal information such as merchandise delivery address by automating the transmission of personal information in the UIM card 12, payment processing would be more simplified.

0034<figref idref="f0008">FIG. 9</figref> is a flowchart illustrating a recharging procedure for a prepaid card according to a fourth embodiment of the present invention.

0035A prepaid card recharging system 74 which received a request for recharging a prepaid card from the user issues a recharging start instruction to the mobile terminal 10. The user transmits recharging request information such as a desired recharging amount, a correspondent financial institution, account information, and authorization information to the prepaid card recharging system 74. In this case, too, it would be desirable that information except for the recharging amount is read out from the UIM card 12 and transmitted. By using transmitted information, the prepaid card recharging system 74 makes an access to the corresponding financial institution 50 and requests a balance inquiry; the financial institution 50 transmits balance information of the corresponding account. The prepaid card recharging system 74 compares the desired recharging amount which the user has entered with the balance of the corresponding account; if the balance turns out to be insufficient, the prepaid card recharging system 74 carries out a recharging failure processing, whereas, if the balance is more than the recharging amount, the prepaid card recharging system 74 requests recharging to the financial institution 50 functioning the same as an account transfer request. In case of acceptance of the recharging request, the prepaid card recharging system 74 transmits a confirmation message for recharging to the mobile terminal 10. The mobile terminal 10 which received the confirmation message for recharging updates balance information of the prepaid card in the UIM card 12 by adding the recharging amount; then, the mobile terminal 10 displays the confirmation message for recharging to the user and stores recharging particulars into the memory of the UIM card 12.

0036This procedure is identical to that of recharging a traffic card using a traffic card issuing system 78.

0037<figref idref="f0009">FIG. 10</figref> is a flowchart illustrating a procedure for issuing tickets according to a fifth embodiment of the present invention and <figref idref="f0010">FIG. 11</figref> is a flowchart illustrating a procedure for using tickets according to a sixth embodiment of the present invention.

0038The said ticket issuing denotes reservations for various cultural performances or movie tickets.

0039When the user selects the ticket issuing and using menu shown in <figref idref="f0004">FIG. 5</figref> and requests ticket purchasing, the mobile terminal 10 transmits a signal of ticket purchasing request to a ticket issuing system 76. The ticket issuing system 76 which received the request provides the mobile terminal 10 with information about tickets available for purchasing (contents of the performance, available seats, or price) . The user selects a ticket to purchase from among displayed ticket information and further selects a payment means from among credit card, debit card, and prepaid card. After completion of selecting a ticket and a payment means by the user, the mobile terminal transmits the corresponding information (information about the selected ticket and the payment means) to the ticket issuing system 76. The ticket issuing system 76 completes the payment process through said procedure of <figref idref="f0005">FIG. 6</figref>, <figref idref="f0006">FIG. 7</figref>, or <figref idref="f0007">FIG. 8</figref> according to the transmitted information and issues the purchased ticket to the mobile terminal 10. The mobile terminal 10 displays information about the issued ticket and stores transaction particulars and ticket information into the memory of the UIM card 12.

0040A procedure for using the tickets issued from such procedure is described below.

0041If the user carries out ticket presentation operations with the mobile terminal 10 before passing through a gate, the mobile terminal 10 transmits ticket information stored in the memory of the UIM card 12 to the payment terminal 30 installed at the gate. The payment terminal of the gate authenticates transmitted ticket information with a subsequent approval of the ticket and transmits an approval message to the mobile terminal 10, thereby displaying the approval message to the user. After completion of the transmission of the approval message, the payment terminal 30 of the gate transmits information indicating ticket use to the ticket issuing system 76 and displays a ticket use message on the mobile terminal 10. When all the procedure has been done, a gate bar, for example, is opened and the user is allowed to proceed.

0042<figref idref="f0011">FIGS. 12 and 13</figref> are diagrams illustrating examples of display window for transaction particulars inquiries according to the present invention.

0043When transactions such as said payment, recharging a prepaid card or a traffic card, and ticket reservation are settled, consequent particulars are all stored in the memory of the UIM card 12 as described previously. The stored information can be displayed assorted according to particular service categories as shown in <figref idref="f0011">FIG. 12 or FIG. 13</figref>. Or, it can be displayed assorted according to a particular search condition such as date, amount, and transaction particulars.

0044The amount of money paid during said payment, ticketing, or recharging a traffic card or a prepaid card may be demanded added to the communications expenses (for example, a telephone bill) of the mobile terminal 10 instead of settlement by a financial institution.

0045In addition, since information such as a mobile identification number (MIN) and PIN is stored in said UIM card 12, even if it is inserted into another mobile terminal 10, the user can use the aforementioned services with his or her own mobile terminal 10 without complicated procedures. Therefore, roaming services both for communications and finance information can be provided.

0046<figref idref="f0012">FIG. 14</figref> is a flowchart illustrating a procedure for issuing an IC card according to a seventh embodiment of the present invention. It is intended that through a wireless communications network or Internet, an IC card such as various identification cards, a license, or a credit card is issued and used online or offline. The present embodiment describes a procedure for issuing a credit card as a specific example of the IC card issuing procedure. In <figref idref="f0012">Fig. 14</figref>, the reference number 141 is installed in said service providing system 70 of <figref idref="f0001">FIG. 1</figref> and the reference number 142 is installed in said card issuing company 40 of <figref idref="f0001">FIG. 1</figref>.

0047First, if a message of card issuing request from an applicant is received at said IC card issuing server 141 through the wireless Internet based on WAP or wired Internet based on Web S301, the said issuing server 141 registers the PIN (Personal Identification Number) of the particular applicant based on said received message of card issuing request; thereafter, the said issuing server 141 provides said applicant with the PIN through WAP or Web and closes the connection with the applicant.

0048Subsequently, said issuing server 141 sends a request to a SMSS (Short Message Service Server) (not shown) of said wireless communications network 20 to notify the corresponding mobile terminal 10 designated by said received message of card issuing request that the applicant is the object of the IC card issuing S303. The said SMSS notifies said mobile terminal 10 of said requested notification about the issuing object through SMSC (Short Message Center) (not shown) in the form of a short message S30₄.

0049The said mobile terminal 10 recognizes that it is the issuing object based on said received SMS message. If said PIN information is entered by the user of said mobile terminal 10, the mobile terminal 10 transmits the entered PIN information to said issuing server 141 S306.

0050The said issuing server decides whether or not the received PIN information from said mobile terminal 10 is identical to said registered PIN information and if the result turned out to be non-identical, closes the transaction S307.

0051Next, if the PIN information is found to be identical at said S307 stage, a mutual authorization process is carried out according to the agreement predetermined by cryptogram so as to authenticate the mutual validity of the IC chip embedded in said mobile terminal 10 (namely, the UIM card 12) and said issuing server 141.

0052After the mutual authorization between said IC chip 12 and said issuing server 141 has been completed in said S308 stage, the said issuing server 141 selects an application program to enable the use of said requested IC card and downloads it to said mobile terminal 10 S310. The said mobile terminal 10 stores the said downloaded application program into the memory of said IC chip 12 and responds by notifying the said issuing server 141 of the completion of the storing process S311.

0053Finally, upon receiving the response from said S311 stage, by providing the server of the corresponding card company 412 with the information indicating the completion of said IC card issuing S312, thereby accomplishing the registration for the use of said issued IC card in real-time, the said issuing server 141 allows the said IC card to be used between said mobile terminal 10 and said payment terminal 30 belonging to said server of the card company 142 by wireless communication such as IrFM communication system S313.

0054In case of a transaction using the aforementioned IC card in said S313 stage, the server of said card company 142 communicates with said payment terminal 30 as the corresponding distribution terminal in association with the server 142 based on the information about said registered IC card for use. The said mobile terminal 10 communicates wirelessly in the form of an IrFM message with said payment terminal 30 based on said application program, thereby enabling said IC card to be used according to its purpose.

0055<figref idref="f0013">FIG. 15</figref> is a flowchart illustrating a procedure for canceling an IC card according to an eighth embodiment of the present invention, more specifically, the procedure of canceling the IC card issued through the procedure described in <figref idref="f0012">FIG. 14</figref>.

0056The said mobile terminal 10, when the predetermined canceling key is entered S401, generates a request for the entrance of the PIN so as to identify the user by displaying a message such as "Enter the PIN input" on a window S402. After the PIN has been entered S403, the said mobile terminal 10 decides whether or not the entered PIN information is identical to the preset PIN information S404 and if the result turned out to be non-identical, requests a re-entrance, whereas, when they are found to be identical, the said mobile terminal 10 transmits a notification message of cancellation request to said issuing server 141 S405.

0057The said issuing server 141 transmits a message of a delete command of the corresponding application program to cancel the IC card to said mobile terminal 10 with the encrypted cancel key of the issuer S406.

0058The said mobile terminal 10 carries out authentication of said received cancel key transmitted according to the predetermined cryptogram S407 and makes a decision on the authentication result S408. When the authentication is completed normally, the said mobile terminal 10 deletes the application program as said IC card downloaded and in use from said S409 stage of <figref idref="f0012">FIG. 14</figref> S409 and transmits a response message notifying the said issuing server 141 of the completion of the deletion S409.

0059) The said issuing server 141 delivers information about the cancellation of the card based on said received response message of the delete completion to the server of the card company 142 as an issuer S410.
