The use of the Universal Product Code (UPC) in conjunction with the laser-scanner-equipped electronic checkout system has made it technologically possible for supermarket stores to operate more efficiently and accurately. At present, more than 90% of the packages in grocery stores have been marked by the manufacturer with laser-scannable UPC symbols and the installation of laser scanning systems is expected to expand into all major chain stores. Areas to be discussed are: system design features, laser-scanning pattern generation, signal-processing logical considerations, UPC characteristics and encodation.
