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.

First claim

The invention claimed is:

1. A security system comprising:
a transceiver/transponder circuit;
at least one integrated circuit comprising at least one antenna for communicating with said transceiver/transponder circuit;
at least one electromagnetic inhibiting element associated with said at least one integrated circuit and configured to inhibit communications with said transceiver/transponder circuit and to secure data in said at least one integrated circuit; and
a coupling e…
