Enhanced security self-service checkout station

摘要

A self-service checkout station (10) includes an item scanner (22) which generates a first signal when it detects a machine readable code associated with an item, a sensor such as a video camera (24) which generates a second signal when the sensor detects a motion used to scan the item across the scanner, a recorder (35) which generates a visual recording of the motion used to scan the item across the scanner, and a processing unit (35) coupled to the scanner, the sensor and the recorder which causes the recorder to play back the visual recording on a display monitor when the processing unit receives the second signal but not the first signal.
