Long range selective RFID system using laser photodetection wakeup

The invention refers to using laser detecting wake-up of long distance the selectivity of rfid. A data transmission system comprises a radio frequency emitter and receiver and the laser device radio frequency identification rfid reader. Data transmission system also comprises on the container of the rfid label it has the label in an electronic circuit is coupled from the laser light there is no illumination the light sensitive device is set in the first state from the laser light irradiating the photosensitive device is located in the second state of the first light sensitive device so as to make rfid label only from the laser beam irradiating the photosensitive device for transmitting signals. When the distance from rfid reader rfid tag 40 feet or more of the remote radio frequency transmitter the rfid tag to provide enough to receiver can be sent by the rfid reader decoding the signal of the power of.
