Bulk Aztec Code Generator

Aztec Code is a square 2D code with a bullseye in the middle. Rail operators, airlines and event organisers print it on tickets because it reads quickly, even on a phone screen or a worn paper ticket.

Unlike a QR code it needs no empty border around it, so it fits small spaces. It has built-in error correction (about 23% of the code can be damaged). Check a result with the barcode scanner; for stacked rows on documents see PDF417, for tiny parts Data Matrix.
