Abstract
A system and device for detecting and/or deactivating a security tag when passing through an electronic article surveillance (EAS) portal. The portal may be oriented by the arrangement of one or more antennas to generate an electromagnetic field at or within the portal to detect and/or deactivate the security tag. The electromagnetic field may detect and/or deactivate a security tag located at any orientation on merchandise as the security tag passes through the portal. The portal may be mounted on a counter at a point-of-sale station in which merchandise having security tags attached thereto are passed through the portal. The portal may also be mounted to a floor in which a shopping cart having merchandise is passed through the portal so that security tags attached to the merchandise in the cart are detected and/or deactivated.
