A system and method for providing wireless synchronized operation of electronic article surveillance (EAS) systems are provided. The method may include communicating wirelessly between each of a plurality of controllers connected to a plurality of detectors of the plurality of EAS systems and receiving with a communications receiver of each of the controllers wireless communications from at least some of the other plurality of controllers. The communications receiver may be separate from a tag detection receiver.

Wireless synchronized operation of pulsed EAS systems

An apparatus for data communication and deactivating an electronic article surveillance tag comprising an antenna for communicating with a transponder located within a predetermined area and a deactivation coil for deactivating an electronic article surveillance tag located within the predetermined area.

Apparatus for data communication and deactivation of electronic article

A data communication and electronic article surveillance tag includes a data communication transponder and an electronic article surveillance tag.

Data communication and electronic article surveillance tag

A multi-bit electronic article surveillance marker includes an antenna circuit and is powered by an interrogation field generated by EAS detection equipment and received by the marker's antenna circuit. The marker generates a multi-bit signal by selectively disturbing the interrogation field. The disturbances may be created by selectively short circuiting the marker's antenna circuit. All of the marker circuitry, including a coil that is part of the antenna circuit, may be provided as circuit elements formed on a semiconductor integrated circuit substrate.
