Abstract
The present invention is directed toward an RFID device that includes a motion sensing mechanism. The motion sensing mechanism is adapted to sense motion of the RFID device and then selectively allow or restrict the RFID device's ability to transmit messages, which may include sensitive data, when the RFID device is placed in an RF field. Thus, the motion sensing mechanism is utilized to control access to data on the RFID device to only instances when the holder of the RFID device moves the RFID device in a predefined sequence of motion(s).
