  • Method of de-activating and activating an electronic article surveillance (EAS) device, and an EAS device
    Patent number: 8749357
    Abstract: A device for use in electronic article surveillance EAS is disclosed which comprises a resonant circuit, typically designed for 8.2 MHz operation, in addition to a transponder, such as RFID, for non-contact communication with a communication station. The RFID transponder can provide a signal to detune the resonant circuit to disable the EAS and optionally another signal to tune or retune the resonant circuit to enable or re-enable the EAS. The detuning and tuning or retuning may preferably be achieved using phase change memory material, configured as a programmable switch having two states with different resistances.
