What to put behind the code
A mobile form with a clear purpose and an appropriate privacy notice.
Print for the place it will live
Starting size: 3 × 3 cm. This is a starting point, not a scanning guarantee. Place it where visitors can pause comfortably after service.
Use a stable sign rather than a moving door or bin lid. Keep the four-module quiet zone intact and use dark modules on a light background. Read the print-size guide.
Where to place it
- Exit counter
- Service completion card
- Visitor information desk
Mistakes to avoid
- Requiring a login unexpectedly
- Collecting unnecessary personal data
- Describing a public link as anonymous without checking the form
Before committing to a print run
Print a proof on the final material. Scan it with more than one phone, from the normal viewing position. Check the opened destination while signed out and confirm it leads to the intended page or action. A readable fallback address or contact detail helps visitors who cannot scan.
