Abstract
Systems and methods for verifying a detachment of a security tag from an article. The methods comprise: using a voltage induced in an internal circuit of the security tag by a magnetic field generated by a detaching unit to power a controller of the security tag; receiving, by the security tag, a first signal sent from the detaching unit; selectively supplying power to an electro-mechanical lock mechanism of the security tag for a certain amount of time to cause a pin to be released from a lock, in response to the first signal; and communicating, from the security tag, a second signal indicating whether or not the pin was released. The voltage is no longer induced in the internal circuit by the detaching unit when the second signal indicates that the pin was released.
