  • Systems and methods for data reading and EAS tag sensing and deactivating at retail checkout
    Patent number: 7495564
    Abstract: Methods of operation of a data reader and security tag deactivation system whereby a data reader such as a barcode scanner is equipped with EAS deactivation coils or modules disposed in the vicinity of the read volume or generally proximate thereto and the system is operable to permit reading of the ID tag (such as the barcode label) on an item, and upon a successful read, the deactivation unit is operable to (1) sense the presence of an EAS tag; (2) if presence of an EAS tag is sensed, energize the deactivation coil/module to deactivate the EAS tag; and (3) sense if the EAS tag is deactivated. If the EAS tag is sensed to have been deactivated, the system signals as such and a next item may be scanned. If the EAS tag is sensed to have not been deactivated, the system proceeds to alternate operational steps to handle the exception.
