Abstract
Systems and methods for operating a marker. The methods comprise: storing energy collected by an energy harvesting element of the marker; using the stored energy to enable operations of the marker's communications element; receiving, by the marker's communications element, a marker deactivation signal transmitted from an external device; and causing either a resonator to be prevented from receiving transmit bursts emitted from an EAS system, a bias element's magnetic field to be normalized, or a resonator to be physically prevented from vibrating, in response to the marker deactivation signal's reception.
