DYNAMICALLY PROGRAMMABLE RFID TRANSPONDER

摘要

A radio frequency transponder, or a device that comprises a radio frequen cy transponder, wherein the radio frequency transponder is operative in invo king self-programming of data stored in the radio frequency transponder. In some implementations the radio frequency transponder selectively enables the transmission of a unique identifier by selectively programming the unique i dentifier stored in the radio frequency transponder. In various implementati ons, the radio frequency transponder programs data stored in the transponder by generating a signal that is reactively coupled to the antenna of the rad io frequency transponder.
