This specification defines the requirements for the symbology known as MaxiCode.  MaxiCode is a fixed-size matrix symbology which is made up of offset rows of hexagonal modules arranged around a unique finder pattern.  This specification specifies the MaxiCode symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters.  MaxiCode includes special encodation modes for use in destination sortation symbols by carriers in the transport industry.
