Technical glossary of Paul Leibinger GmbH & Co. KG

The barcode is an optically-electronically machine-legible writing, consisting of several wide and parallel bars and gaps. With optical detectors (known as barcode readers, so-called scanners) or cameras the writing is read automatically and electronically processed. In contrast to the 2D Data Matrix code the barcode is only one-dimensional.

There are many different types of barcodes – according to their purpose and applicability. Almost all marking and coding systems are able to produce these codes.
