Abstract:
A scanner for detecting and decoding primary and supplemental bar code labels, comprising:a laser for generating light; a video receiver assembly for detecting light patterns produced by a reflection of the light generated by the laser from one or more bar code labels passing within a field of view ofthe video receiver assembly and producing data based on the light patterns; and a controller for analyzing the data produced by the video receiver assembly to detect a primary bar code label, the controller being operative upon detection of the primary bar code label to search a database for the bar code represented by the primary bar code label and retrieve a value associated with the bar code, the controller being operative to conduct a search for a supplemental bar code label based on the retrieved value associated with the retrieved bar code wherein the retrieved value determines the time to be spent searching for the supplemental bar code label.
