Your stamp card lives on the phone, not in a drawer.
With Thekla, your shop's card goes into your guests' Apple Wallet or Google Wallet. One scan at the counter, and it's there.

What it gives you
No app, no form
Your guest scans the QR code and taps "Add to wallet". That's all they have to do.
On iPhone and Android
The card works in Apple Wallet on iPhone and in Google Wallet on Android.
You set the rule
You decide how many stamps it takes to get a reward and what the reward is.
How it works
Your guest scans the QR code at the counter and taps "Add to wallet".
On every visit your team scans the card, and the stamp is there instantly.
When the card is full, it lets your guest know, and they come back.
Quick questions
Do my guests need an app?
No. The card goes into Apple Wallet or Google Wallet, which is already on almost every smartphone.
What about guests who prefer the paper card?
You can keep it running alongside. Nobody has to switch.
