ABSTRACT:
A system and method of verifying item placement on a security scale. The system includes a computer for receiving incremental weight signals from a security weight scale, wherein some of the incremental weight signals are unrelated to placement of items on the security weight scale, and an item detector for detecting movement of the item from a scanner following scanning of the item and for generating an item detection signal, wherein the computer ignores the incremental weight signal unless it receives the item detection signal within a predetermined time period preceding receipt of the incremental weight signal.
