Abstract:
1. A method of reading a plurality of bar codes from two or more items moved substantially simultaneously through a scan volume of a bar code scanner comprising the steps of: a) obtaining data for the plurality of bar codes from a detector in the bar code scanner as said items move through the scan volume; b) determining position information associated with the data; c) distinguishing data associated with each bar code using the position information; d) assembling the plurality of bar codes from the data and determining the number of bar codes successfully read; e) storing the position information in a memory; f) formatting only the bar codes that are unreadable into a format usable by a computer; g) repeating steps a) through d) during a rescan of the bar codes; and h) determining that the re-scan has occurred by comparing newly acquired position information with stored position information.
