Destructible RFID transponder
View Patent ↗A tamper resistant electronic tag that wirelessly receives and transmits unique subscriber information to and from a transceiver so that financial transactions can occur quickly and seamlessly. In a preferred embodiment, the tag works in conjunction with a roadway toll booth and is mounted onto a flat interior surface of a vehicle, where it can receive and transmit electronic information to and from a toll booth. That allows a driver to pay the toll fee without having to stop his vehicle. The electronic tag includes a plastic protective card for carrying a circuit. The circuit includes an integrated circuit that is adhesively attached to the protective card. The protective card and circuit are then attached to the flat surface. When the protective card is removed, the integrated circuit is pulled off with the protective card while the rest of the circuit remains attached to the flat surface, thereby severing the circuit, and rendering it inoperable. This prevents the unwanted tampering and unauthorized use of the electronic tag.
