Systems and methods for operating a marker that involve receiving, by a Radio Frequency Identification ('RFID') element of the marker, an RFID deactivation signal; and responsive to the RFID deactivation signal, supplying power to a detuner element of the marker 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.

Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal transmitted from a transmit circuit using a receive circuit of the security tag; inducing a voltage in the receive circuit of the security tag while the first wireless signal is being received; performing operations by the controller to selectively close a switch when the voltage is being induced in the receive circuit; and causing a release of a mechanical component of the security tag by allowing energy to flow from the receive circuit to the mechanical component when the switch is closed.

Systems and methods for deactivating an Electronic Article Surveillance ('EAS') tag. The methods comprising: using an AC drive signal to charge an energy storage component of the tag deactivator; selectively actuating a switch so that a closed circuit is formed between the energy storage component and at least one deactivation coil of the tag deactivator; generating a tag deactivation field to deactivate the EAS tag by energizing the at least one deactivation coil with current supplied from the energy storage component; and using a step down transformer, disposed between the energy storage component and the at least one deactivation coil, to decrease a frequency of a decaying coil current waveform representing a current flowing through the at least one deactivation coil.

Aspects of the present disclosure include methods, apparatus, and systems for deactivating an AM tag including receiving a deactivation signal via a first inductive coil, storing electrical charges generated from the deactivation signal in a capacitor, and discharging the electrical charges through a second inductive coil, wherein: a first bias strip in the demagnetized state and a second bias strip cause a resonator to vibrate at a first resonant frequency corresponding to an activated state of the AM tag, the discharging magnetizes the first bias strip from a demagnetized state to a magnetized state, and the first bias strip in the magnetized state and the second bias strip cause the resonator to vibrate at a second resonant frequency different than the first resonant frequency, wherein the resonator vibrating at the second resonant frequency corresponds to a deactivated state of the AM tag.

Systems and methods for operating a marker. The method comprising: receiving, by a communications element of the marker, a marker deactivation signal from an external device; and causing a coil surrounding at least the marker's resonator to be shorted in response to the marker deactivation signal, by supplying power to a deactivation element so that the deactivation element switches from an open state to a closed state. In some scenarios, the power is supplied by an energy harvesting element disposed in the marker.

A system is provided. The system includes a detacher. The detacher includes a field source. The field source is arranged to provide a first magnetic field when power is applied to the field source. The detacher further includes a magnet arranged to provide a second magnetic field. The magnet is movable from a non-detach position to a detach position when exposed to the first magnetic field. The second magnetic field is arranged to unlock a security tag when the magnet is at the detach location. The system further includes an activation device. The activation device includes a processor configured to trigger power to be supplied to the field source.

Methods, systems and devices for providing an interrogation signal from a handheld deactivation device for identifying a security tag. Identifying the security tag includes initiating an interrogation signal, wherein the interrogation signal includes plurality of transmission bursts and a plurality of random time periods to wait between transmission bursts such that a unique time period elapses between each of the plurality of transmission bursts. The interrogation signal is then transmitted by transmitting each of the plurality of transmission bursts for a portion of a duty cycle and interrupting transmission between each of the plurality of transmission bursts for one of the plurality of random time periods such that a unique and random time period elapses between each of the plurality of transmission bursts. The period transmission of the interrogation signal provides for improved battery life of a handheld scanning and deactivation device.
