Ten code types, a design editor that checks its own contrast, a library that survives staff turnover, and scan data per code. The printed square never has to change.
You make and print a code once. You change where it goes as often as the season, the menu or the campaign does.
Every change re-scores contrast and quiet zone against the error-correction level you are on. When a colour pair drops below the threshold the preview says so before you export, not after the print run.
There is no camera on a desktop worth using, so the web reads codes from files instead. Drop a poster proof, an artwork export or a screenshot from a colleague, and Cue shows the destination as text before anything opens.
Cue for iPhone scans with the camera, saves offline and syncs the same library. Repoint a code from the pavement outside the shop, then see it land in the workspace before you are back at the counter.
Static codes are free and need no account.
