barcode

The printed code used for recognition by a barcode scanner (barcode reader). The "bar" in barcode comes from the ubiquitous, one-dimensional (1D) UPC barcode found on countless product packages. Several two-dimensional (2D) barcodes are also in wide use, but they are not 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 barcode scanner, mobile tagging, point of sale and AIM. Contrast with RFID.
