Aztec barcodes

Aztec is a matrix symbology that supports the entire ASCII character set and offers several error checking modes. Aztec symbols are square and may be read at any orientation.

The symbol is made up of squares which "grow" from the centre around a centre mark. The size of the symbol is characterised by the number of "layers" outside the centre mark, and this can range from 1 – 32.
