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.
