摘要:
Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal 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 a controller to selectively close a switch while the voltage is being induced in the circuit; 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; and performing operations by the controller to prevent damage to the mechanical component as a result of the security tag being a certain distance from an external device.
