What is Aztec Code used for?
Airline boarding passes, rail tickets and ID documents: the bullseye finder needs no quiet zone, so symbols stay small on screens and thermal prints.

Questions
Aztec Code Reader & Scanner, answered.
If you manage servers by hand, see the engineering services behind this tools series.
What about tiny Aztec Runes?
Aztec Runes are separate fixed 11×11 symbols carrying one value 0–255. The reader reports them distinctly from full Aztec Code payloads.
Why did my Aztec Code fail to read?
Phone screens moiré under some lighting — raise brightness, hold steady, and fill the frame with the symbol.
Are my images uploaded?
No. Pixels and decoded payloads stay in memory on this device. The page makes no network requests with your data and clears the result after ten idle minutes.
