Abstract
A radio frequency identification (RFID) tag comprises RFID circuitry, an antenna, and a detector responsive to electromagnetic radiation of a predetermined frequency and for controlling cooperation between the RFID circuitry and the antenna when electromagnetic radiation of the predetermined frequency is detected. The detector may be responsive to light of the predetermined frequency to enable cooperation between the RFID circuitry and the antenna when light of the predetermined frequency is detected. Alternatively, the detector may be responsive to light of the predetermined frequency to disable cooperation between the RFID circuitry and the antenna when light of the predetermined frequency is detected.
