Standard Code 128 (ISO 15417) - Barcode Type¶

One of the most ubiquitous one-dimensional barcode symbologies, Code 128 was developed in 1981 by Computer Identics. This symbology supports full ASCII text and uses a three-mode system to compress the data into a smaller symbol. Zint automatically switches between modes and adds a modulo-103 check digit. Code 128 is the default barcode symbology used by Zint. In addition, Zint supports the encoding of Latin-1 (non-English) characters in Code 128 symbols [1].
