is a high-capacity 2D matrix barcode symbology. It can encode ASCII and extended ASCII characters.
ISO/IEC 24778:2008 standard defines Aztec-Code.
Its unique centered finder pattern and module placement algorithm makes Aztec-Code looks like a maelstrom.
Aztec-code size ranges between 15 X 15 modules and 151 x 151 modules. Each module is a square of black or white.
When using the Full Range Mode of 151 x 151 modules and with 23% error correction, Aztec-Code can encode up to 3000 characters or 3750 numbers.
