Abstract
A method for providing a secure communications channel for the transmission of large amounts of information between a RFID tag and a RFID reader. A laser beam is utilized to carry information and power from the RFID reader to the RFID tag. Thus, the laser beam has a dual use as an information carrier and a source of power for the RFID tag. Thus, only individuals and/or equipment that can both see the laser transmission and hear the RFID transmission can eavesdrop on the RFID tag RFID reader transmissions. This invention allows the use of complex algorithms to protect data being communicated because they can use the increased level of power available to the RDIF tag.
