Abstract: A security system includes an integrated circuit and a transceiver/transponder circuit. The integrated circuit includes an antenna for communicating with the transceiver/transponder circuit. An inhibiting element is associated with the integrated circuit for inhibiting communications with the transceiver/transponder circuit and for securing the data contained in the integrated circuit. The inhibiting element is an electromagnetic inhibiting element. The security system further includes a coupling element associated with the antenna of the integrated circuit for temporarily deactivating the electromagnetic inhibiting element to allow communications between the integrated circuit and the transceiver/transponder circuit.
