ABSTRACT:
Systems and techniques for prevention of double scans of bar codes by identifying the possibility of ambiguities in position information estimated upon detection of a bar code. A bar code scanner estimates position information for a bar code upon detection of the bar code. Timing information for each detection and the accompanying position estimate is maintained, and lapses of time between detections and accompanying position estimates are noted. When successive scans of identical bar code information occur, the lapses of time are evaluated in light of predetermined criteria to determine whether or not an ambiguity exists that prevents reliable identification the scans as a double scan of the same bar code or successive scans of separate but identical bar codes.
