Know it scans before you print
Every design is decoded in your browser at three sizes, with camera blur. Lighten the ink to see the score react.
- Print size
Print it big enough
The minimum size depends on how far away people scan from and how much the code holds.

Change the link after printing
A dynamic code opens a short link you can point somewhere new at any time. Free accounts get 10.

Scans over time, countries, devices, browsers and referrers for every dynamic code. Free accounts keep 90 days.
