Abstract
A bar code scanning system and method for scanning a bar code containing a key including successively scanning the bar code and providing, for each scan, a plurality of data elements forming a scan fragment for at least a portion of the bar code, identifying each fragment containing a portion of a reference key, detecting when there has been a match between a reference key and the identified key fragments, determining if a complete key has been constructed from the key fragments, calculating a displacement between the key fragments which constructed the complete key, and aligning data fragments of the bar code by placing each successive data fragment in alignment with the previous data fragment offset by the amount of the displacement.
