Abstract
Systems and methods for operating a marker. The method comprising: receiving, by a Radio Frequency Identification (“RFID”) element of the marker, an RFID deactivation signal transmitted from an external device; and responsive to the RFID deactivation signal, supplying power from the RFID element to a detuner element so that the detuner element switches from a first state to a second state. The marker's resonant frequency is changed to a first value that falls outside of an Electronic Article Surveillance (“EAS”) systems operating frequency range when the detuner element switches from the first state to the second state.

A method for operating a marker, comprising:
- receiving, by a Radio Frequency Identification (“RFID”) element of the marker, an RFID deactivation signal transmitted from an external device;
- and
- responsive to the RFID deactivation signal, supplying power from the RFID element to a detuner element so that the detuner element switches from a first state to a second state;
- wherein the marker's resonant frequency is changed to a first value that falls outside of an Electronic Article Surveillance (“EAS”) systems operating frequency range when the detuner element switches from the first state to the second state.
A marker, comprising:
- a Radio Frequency Identification (“RFID”) element configured to receive an RFID deactivation signal transmitted from an external device and supply power to a detuner element in response to the RFID deactivation signal's reception;
- and
- a detuner element electronically connected to the RFID element and configured to switch from a first state to a second state when power is supplied from the RFID element;
- wherein the marker's resonant frequency is changed to a first value that falls outside of an Electronic Article Surveillance (“EAS”) systems operating frequency range when the detuner element switches from the first state to the second state.
