ABSTRACT:
A deactivator for magnetically altering a tag used in an electromagnetic article surveillance system. The deactivator is adapted for use in conventional, pre-existing check-out counters. An elongated cover plate is secured on top of a transition plate which spans the distance between a check-out counter conveyor belt and countertop. An elongated magnet assembly is positioned between the cover plate and the transition plate. The magnet assembly provides a magnetic field above the cover plate that is capable of deactivating a magnetically alterable tag secured to an object to be purchased as the object is passed over the cover plate from the conveyor belt to the countertop.
