Most common one-dimensional barcodes are based on a binary principle with a number of narrow and wide bars and/or gaps. The sequence of these bars or gaps results in a certain numeric or alphanumeric message. A barcode is therefore actually nothing more than a graphic Morse code.

The two-dimensional matrix codes are represented by mathematically placed black and white pixels. They have many advantages over 1D barcodes. Significantly lower space requirements, very high reading reliability even with poor print quality or damage as well as an increased amount of data that can be displayed are the outstanding features.

The barcode is read optically. The different reflection of the lines, gaps or pixels creates a pulse pattern in the optical receiver that corresponds electronically to this sequence. This pattern is then interpreted as data by a processor-controlled evaluation (decoding).

A variety of barcode readers are available for different applications, from simple hand-held scanners with WiFi or cable to glove scanners and CCD scanners with cash register connection. We help you select the right devices and integrate them into your system.
