Code 128

Introduced in 1981 by Computer Identics, is used in several applications that include general industrial, inventory, and retail container markings. Code 128 encodes all 128 ASCII (0 - 127)characters with a choice of 3 start code sets:

Start Code A: encodes all alphanumeric characters in uppercase.

Start Code B: encodes all alphanumeric characters in uppercase and/or lowercase.

Start Code C: encodes numbers in double density pairs from 00 to 99.

Has variable length with a format continuous and linear, can be scanned in both directions as well as a check digit can be included.

A new version of Code 128, the widely used alphanumeric barcode symbology, formalizes a series of enhancements made to the specification by the International Organization of Standards and the European Standardization Bureau over the past 15 years. The new Code 128 now supports an extended Roman character set represented by ASCII values 128 to 255. This extended character set includes many of the accent marks found in European languages but not supported previously in the specification.
