Aztec Code Generator: what to know
An Aztec code is a square 2D barcode built around a bullseye of nested squares in the centre. Scanners find the bullseye first and read outwards, so the code needs no blank quiet zone and can sit right up against other content, which makes it a favourite for tickets shown on phone screens.
Aztec codes come in compact sizes for short data and full sizes that hold up to 3,832 digits or 1,914 bytes, with Reed-Solomon error correction set as a percentage of the symbol. The generator encodes your text into the smallest Aztec symbol that fits with the error correction chosen.
Rail operators across Europe and many airlines use Aztec codes on e-tickets and mobile boarding passes, following the IATA boarding pass standard, which allows Aztec alongside PDF417 and QR codes.
Popular uses
- Train and transit e-tickets
- Mobile boarding passes and event tickets
- Tickets and passes shown on a phone screen
- Labels where there's no room for a quiet zone
Tips for the best result
- Increase the screen brightness when scanning an Aztec code from a phone.
- Even though it needs no quiet zone, a small margin helps scanners in bright light.
- Test the code with the scanner model your venue or operator uses.
