RFID warning intel signal-grit system

A system for remote detection of troop movement using granular radio-frequency identification tags that can respond with a signal when altered by that movement, the system comprising:

• a scanner comprising a radio-frequency transmitter, a battery, and a circuit to transmit an inquiring signal and retransmit a responding signal received by the scanner;
• a plurality of radio-frequency identification tags, wherein each radio-frequency identification tag in the plurality of radio-frequency identification tags comprises:
• a radio-frequency identification chip that generates the responding signal and has a maximum dimension in any direction that is no larger than 6 millimeters,
• an antenna connected to a radio-frequency identification chip, wherein the antenna:
• energizes the radio-frequency identification chip when it receives the inquiring signal from the scanner;
• and
• can transmit the responding signal when the antenna is activated;
• a conductor formed so as to short circuit the antenna and preclude the antenna from activating and transmitting the responding signal, the conductor comprising a frangible material that breaks, disconnects the short circuit and activates the antenna when the conductor is stepped on by a person walking on the radio-frequency identification tag;
• and,
• a remote station configured to receive the responding signal retransmitted by the scanner.
