A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.
These codes can carry much more information in each symbol. Data Matrix has been chosen as the 2-D symbology used with ISBT 128 in labelling applications. ISBT 128 also supports the use of Radio frequency identification (RFID) chips that can carry encoded information, which are being developed for medical products of human origin.
The GS1-128 symbology is a subset of the more general Code 128 symbology. By agreement between AIM and GS1, use of the Function 1 Symbol Character (FNC1) in Code 128 symbols in the first symbol character position following the start character has been reserved exclusively for the GS1 system. Code 128 is fully described in ISO/IEC 15417
Williams also developed Code 128, and the structure of 16K is based on Code 128. Not coincidentally, 128 squared happened to equal 16,384 or 16K for short. Code 16K resolved an inherent problem with Code 49. Code 49's structure requires a large amount of memory for encoding and decoding tables and algorithms. 16K is a stacked symbology. [41] [42]
DotCode barcode was invented in 2008 [1] by Dr. Andrew Longacre from Hand Held Products company and standardized in 2009 [6] by AIM as “Bar code symbology specification - DotCode”. [7] In 2019 DotCode was reviewed as “ISS DotCode Symbology Specification 4.0”. [2] Set of patents is registered, which are related with DotCode encoding and ...

[9] [10] Codablock A was based on stacked Code 39 barcodes and wasn’t widely used because of Code 39 restrictions. The next Codablock F [11] [12] was based on stacked Code 128 symbology and was standardized as AIM standard in 1995. [13] As this time Codablock F is officially accessed as historical standard and isn’t recommended to use in ...
