Coffee shops are ideal for wallet stamp cards: frequent visits, simple rewards, and counter-based scanning.
Replace paper punch cards
Customers add a digital card once and keep it on their phone.
Scan at checkout
Baristas scan to add a stamp in seconds during payment.
Show progress visually
Stamp artwork updates on the pass so progress is obvious without opening an app.
Remind regulars nearby
Use relevant locations sparingly to bring back customers who are one stamp away.
