Aztec Code is a high density 2 dimensional matrix style bar code symbology that can encode up to 3832 numeric or 3067 alphabetic characters or 1914 bytes of data. The symbol is built on a square grid with a bulls-eye pattern at its center. Data is encoded in a series of "layers" that circle around the bullseye pattern. Each additional layer completely surrounds the previous layer thus causing the symbol to grow in size as more data is encoded yet the symbol remains square. Aztec's primary features include: a wide range of sizes allowing both small and large messages to be encoded, orientation independent scanning and a user selectable error
Aztec Matrix size ranges between 15 X 15 modules and 177 x 177 modules. Each module is either black or white.
User can select symbol size and error-correction level. Higher level means less data capacity and less decoding error chance.
There are 36 different symbol sizes available. And there are also a wide-range of error correction levels to choose from.
