US Patent 7389918 Automatic electronic article surveillance for self-checkout

A self checkout system/terminal includes an electronic article surveillance (EAS) system. The EAS system includes an EAS detector and an EAS deactivator. EAS tag detection is associated with a purchase transaction event, such as scanning or bagging of an item. After EAS tag detection, the customer is directed to deactivate the EAS tag. Some of the self-service checkout terminal (SCOT) operation/functionality may be paused during an EAS tag deactivation period. The subject EAS system and/or process eliminates the need to deactivate every item, thereby streamlining the self checkout process when EAS is used in a store.
