Barcodes

standard_barcodesA barcode is an optical machine-readable representation of data. Originally, bar codes represented data in the widths (lines) and the spacings of parallel lines and may be referred to as linear or 1D (1 dimensional) barcodes or symbologies. But they also come in patterns of squares, dots, hexagons and other geometric patterns within images termed 2D (2 dimensional) matrix codes or symbologies. In spite of there being no bars, 2D systems are generally referred to as barcodes as well.

The first use of barcodes was originally designed to automate shopping checkout systems, a task where they have become almost universal today. Their use has spread to many other roles as well, tasks that are generically referred to as Auto ID Data Capture (AIDC).

Barcodes can be read by optical scanners called barcode readers, such as those available with the Scantron iNSIGHT products, or scanned from an image by special software such as ScanTools +, all supplied by MurrayData.
