Byte mode, UTF-8. Level M rebuilds the payload with up to ~15% of the symbol damaged, and the mask is the lowest-penalty of the eight. Keep the light border when you place it: scanners need that quiet zone.

The common case is getting something from this machine onto a phone without emailing it to yourself: a staging URL, a long link, the Wi-Fi password for a guest. A code on screen is faster than any of the alternatives.

The code is generated locally with a choice of error-correction level and can be saved as PNG or SVG. Nothing is uploaded, which is the point when the payload is a password.
