Abstract
A radio frequency identity (RFID) tag. The tag comprises a processor, a memory, wherein the memory stores private information and public information, and a radio transceiver configured to receive a request for information from an RFID reader and to transmit a reply to the request for information. The tag further comprises an application stored in the memory that, when executed by the processor, parses a request for information from the RFID reader received by the radio transceiver, and determines whether the RFID reader is authorized to receive the private information. When the RFID reader is determined to be authorized, the application reads the private information from the memory and sends the private information to the radio transceiver to transmit; when the RFID reader is determined to not be authorized, the application reads the public information and sends the public information to the radio transceiver to transmit.
