Proximity detaching for electronic article surveillance tags

摘要

A reusable EAS tag that is detachable from an article by placing the EAS tag in proximity to a detaching device is provided. The tag includes an energy coupler, a micro-actuator, and a clamping mechanism. The detaching device transmits a signal to the EAS tag to signal detachment, which is received by the energy coupler. The energy coupler converts the energy from the transmitted signal to electrical energy and delivers the electrical energy to the actuator. The actuator converts the electrical energy to mechanical energy to actuate the clamping mechanism and release the tag's locking or clamping mechanism for removal of the tag from the article to which it is attached.
