Abstract
A bar code communication system and method uses a bar code reader to scan a bar code to develop an audible signal that is acoustically coupled to a telephone line. The signal on the telephone line is received by a called station, decoded and the content of the bar code reported back to the calling party, using voice synthesis, for confirmation. The received signal may then be used to control a VCR or other external apparatus.
