How do I give a stamp and redeem a reward?

Scan, +1, redeem — and what to do if the camera won’t read the code.

Open the Scan page. The camera keeps watching, so you don’t need to press a button for the next guest.
Hold the QR code on the guest’s card up to the camera. The card and its stamp count appear.
Tap “+1 stamp”. If the guest bought more, the “+2” or “+3” button gives several stamps at once.
When the card is full, the screen brings redemption to the front. Hand over the reward and tap “Redeem reward”. The card starts a new round, and any extra stamps are kept.

If the camera won’t read the code

In poor light, turn on the torch in the camera view (if your device supports it), or ask the guest to turn up their screen brightness.
Type in the 6-character code shown on the card.

Tip: With the “New guest card” button you can also show the card QR code on your own screen if the guest can’t find the counter card.
