bar code - Computer Definition
The printed code used for recognition by a bar code scanner (bar code reader). The "bar" in bar code comes from the ubiquitous, one-dimensional (1D) UPC bar code found on countless product packages. Several two-dimensional (2D) bar codes are also in wide use, but they are not really as bar-like as the UPC. The 2D codes are scanned horizontally and vertically and hold considerably more data. All the 2D examples below contain the same data: the URL for www.computerlanguage.com. See bar code scanner, mobile tagging, point of sale and AIM. Contrast with RFID.

bar code - Cultural Definition
A series of parallel lines that can be read by an optical scanner and decoded by a computer into usable information. The ten-line Universal Product Code (UPC) on the packaging of retail items is an example of this. The key to this code is the variation in line thickness and separation.
