A system for remote detection of troop movement uses granular RFID tags that can respond with a signal when altered by that movement. The system includes a scanner, multiple granular-size radio-frequency identification tags, a conductor and a remote station. Each of the RFID tags includes a RFID chip that generates a responding signal to an interrogating signal from the scanner. Each RFID tag has an antenna so that the RFID tag can transmit the responding signal, but can do so only after the antenna is activated. A conductor is formed so as to short circuit the antenna and preclude the antenna from activating and transmitting the responding signal. The conductor breaks, and activates the antenna when the conductor is stepped on by a person walking on the RFID tag. The system includes a remote station configured to receive the responding signal retransmitted by the scanner.
