Aztec Code Generator

An Aztec code is a 2D barcode with a square 'bullseye' finder pattern at its center resembling a target; the code grows outward from this center in layers. Its most distinctive feature is that it needs no separate 'quiet zone' around it, which makes it handy in tight spaces and on screens.

Because it needs no quiet zone, an Aztec typically occupies a smaller print area than a QR code for the same information. That's why it's common on rail, airline and public-transport tickets; it reads reliably on both paper tickets and phone screens.

Aztec uses adjustable Reed-Solomon-based error correction; the default level typically adds a certain redundancy to the data, and raising it increases resilience to damage. The central bullseye helps a scanner align the code quickly from any angle.

Aztec is an alternative to other 2D formats like Data Matrix and PDF417; it's ideal for carrying short-to-medium data in a small area. For content needing broader phone support see the QR code generator, and for high-capacity document data the PDF417 generator.
