Scanning
The defaults suit most codes. Error correction is how much of the code can be scratched or covered and still scan; higher makes a denser code. Pick Large for print.
Scanners use the empty border to find the code. The standard is 4 squares wide.
Design
A frame tells people what to do with the code. It uses your code color, set under Color.
Your logo stays on your device. With a logo, the code switches to the highest error correction so it still scans.
Keep the code dark and the background light so phones can read it.
The three corner squares change to match. Test any style with a phone camera before printing.
To keep the code, right-click it (or press and hold on a phone) and choose Save image.
