SYSTEMS AND METHODS FOR DATA READING AND EAS TAG SENSING AND DEACTIVATING AT RETAIL CHECKOUT

摘要

Methods of operation for data reader and security tag deactivation system (10)whereby a data reader is equipped with EAS deactivation coils/modules (14)disposed in the vicinity of the read volume or generally proximate thereto.System (10) is operable to permit reading of the ID tag (5) on an item, andupon a successful read, the deactivation unit (12) is operable to (1) sensepresence of an EAS tag (5); (2) if presence of EAS tag (5) is sensed, energizethe deactivation coil/module (14) to deactivate the EAS tag (5); (3) sense ifEAS tag (5) is deactivated. If EAS tag (5) is sensed to have been deactivated,the system signals and next item is scanned. Also, it may be operable to urgethe operator to return an item to the read volume to enhance EAS tagdeactivation, one method being by delaying good read acknowledgment untildetermining that the EAS tag (5) which may have been previously detected hassubsequently been deactivated.
