Abstract

In accordance with the teachings of the present invention, an electronic deactivation device for RFID surveillance and storage is provided. In a particular embodiment, a deactivateable radio frequency identification device includes a capacitor and a passive component coupled with a RFID circuit, wherein the capacitor is operable to be disabled upon receipt of a signal of sufficient magnetic amplitude, and wherein disabling the capacitor disables the circuit. In another embodiment, a deactivateable radio frequency identification device includes a capacitor and an active component coupled with a RFID circuit, wherein the capacitor is operable to be disabled upon receipt of a signal of sufficient magnetic amplitude, and wherein disabling the capacitor disables the circuit.

Claims
