What to put behind the code
A secure checkout URL from your payment provider, with the correct merchant identity.
Print for the place it will live
Starting size: 3 × 3 cm. This is a starting point, not a scanning guarantee. Allow a close scan before the customer confirms any amount.
Use tamper-evident placement and inspect displayed codes for replacement stickers. Keep the four-module quiet zone intact and use dark modules on a light background. Read the print-size guide.
Where to place it
- Checkout counter
- Invoice payment instructions
- Charity payment desk
Mistakes to avoid
- Treating a scan as proof of payment
- Embedding card details
- Leaving a replaced sticker unnoticed
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.
