Aztec Code

Aztec Code is a two-dimensional (2-D) general-purpose matrix symbology that is designed to have higher accuracy than other 2-D symbologies. An Aztec Code symbol can encode up to 3,832 numeric digits; 3,067 alphabetic characters; or 1,914 bytes of data. The symbol size and the degree of error correction can be configured at label design time or configured to change automatically in response to the length of the data. Printing white on black is an option.

Aztec Code was developed in 1995 by Andrew Longacre and Robert Hussey at Welch Allyn, Inc. The symbology is in the public domain. The code's name is derived from the resemblance of the central finder pattern to an Aztec pyramid that is seen from above.

Aztec Code is defined in ISO/IEC 24778 Information technology - Automatic identification and data capture techniques - Aztec Code bar code symbology specification.
