摘要
Mechanically and reversibly activating or deactivating a radio frequency identification (RFID) data tag. An RFID tag includes an RFID chip for storing an RFID code, an antenna for communicating a radio frequency (RF) signal, and a mechanical switch coupling the RFID chip to the antenna. Closing the mechanical switch enables the RFID chip and the antenna to communicate the RFID code via the RF signal.
