Go into the first field, the second part ("DEF") would go into the second field. The can be used to move the focus from one field to the next. This can be very useful: Consider a data entry When scanning this code, the barcode scanner will put out "ABC", followed by the, then "DEF".

Mixed data ("ABCDEF>"), resulting in a symbol that starts as Code 128 B to encode "ABC", then shifts to Code 128 A to encode the, then Note that this code is wider than the previous example although less data is encoded:

Mixed data, resulting in a Code 128 B full ASCII symbol (note the difference in the first three bars that encode the start character or symbol). Purely numeric code, resulting in a Code 128 C symbol: In principle, Code 128 could be created without a check digit, however, all common barcode readers and scanners will expect a symbol to carry a check digit. The check digit will not be appended to the readable text under the code, likewise it is usually not transmitted by the scanner with the encoded data.

Usually the barcode software that generates the code will calculate the check digit automatically. For a sample calculation, see the Wikipedia article on Code 128. All characters of a symbol are added up and modulo dividedīy 103. Symbology like Aztec or Datamatrix with dedicated supportįor non-ASCII, emoji or Unicode data might be a better choice.Ĭode 128 uses a Modulo 103 checksum algorithm. However, this feature is not widely supported. ÄÖÜ) can be encoded in a Code 128 symbolīy using a special character (FNC4). In principle non-ASCII characters like German umlauts (e.g. Usually the code set selection and switching within a symbol is handled by the barcode software thatĪccented, diacritic characters, emoji with Code 128 The code set to use is indicated to the scanner by the start symbol or start character.Īlso available are various mode switching or shift characters to switch from one set to another within a barcode symbol. The code sets differ in compactness and encodable character set.Ĭode 128 A: Partial ASCII set, no lower case, but ASCII control chars (TAB, CR/LF etc.)Ĭode 128 B: Full ASCII set, no ASCII control charsĬode 128 C: Only digits 0-9, encoded in pairs, very compact code Three different code sets are defined for Code 128 (dubbed A, B, and C) that determine how the code is interpretedīy the barcode scanner. SeeĬode 128 GS1 for a discussion of Code 128 GS1 but read this page first.) Code 128 code sets A, B, C and start characters UPS) and in retail as Code 128 EAN / UCC (This variation is now known as 128 GS1. This barcode symbology is widely used for warehouse management, in the transport industry (e.g.

Code 128 was developed by Computer Identics in 1981 and has become very popular over the years.
