Code One

Code One

Code One was the earliest public domain 2D matrix-style barcode. It is used by the health care and recycling industry and can encode full 256 character extended-ASCII.

Also known as: Code 1, Code 1S.

Standards: AIM USS - Code One.

Data and Options

• The data field can consist of any ASCII data for standard and T-type symbols. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1. When supported by the receiver characters from other code pages can be encoded using Extended Channel Interpretation (ECI).
• Note: S-type symbols are special in that they represent a numeric value so may only contain digits.
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters, e.g. ^029 for GS, etc.
• When the parsefnc option is specified, non-data function characters can be specified by escape sequences:
  • ^FNC1: FNC1
  • ^FNC3: FNC3
  • ^ECI000000 to ^ECI999999: ECI indicators
• The version option is used to specify the size and type of the symbol:
  • A, B, C, D, E, F, G, H - for standard format symbols (default automatic selection)
  • version=T-16, version=T-32, version=T-48 - T-type symbols
  • version=S-10, version=S-20, version=S-30 - S-type symbols
