Aztec

Aztec Barcode is a 2D barcode which can encode 8 bit data, including all ASCII characters (binary values 0 - 127) and the remaining values (binary values 128 - 255). The barcode also includes error detection and correction to compensate for damaged barcodes. Error correction typically takes up 23% of the code space.

The Aztec barcode has three different code sizes:

Full - Full code size.
Compact - Compact code size.
Rune - A special barcode which can only encode values 000 - 255.
