Abstract
A system and method of providing security during operation of a self-service checkout terminal by detecting movement of an item within a scanner zone associated with the terminal with a video system and generating a scanning-attempt control signal in response thereto. The method also includes the step of generating an item-entered control signal if a product code associated with the item is entered into the terminal. The method further includes the step of generating an attempt-failed control signal if the item-entered control signal is not generated in response to the movement of the item within the scanner zone. Moreover, the method includes the step of detecting insertion of the item into a grocery container with the video system and generating a detection control signal in response thereto. The method yet further includes the step of generating an invalid-use control signal if the item-entered control signal has not been generated prior to generation of the detection control signal.
