Stamkunder began as the digital loyalty card at Lagoni Kaffebar, a café in Helsingør, Denmark. Customers scan a code at the counter, and Michael and his staff stamp it in one tap. That’s the card we turned into Stamkunder, so other shops can have it too.

No crumpled paper cards. No new app.
Just a simple habit that goes home with your customer.
Customers scan the code at the counter and get their card right in the phone’s browser.
Staff scan the customer’s card and give a stamp in one tap.
Customers follow their stamps on their phone. When the card is full, the reward is waiting.
From cozy coffee bar to sharp barber.
Pick a style and watch the card change.

Customers collect stamps when they buy. When the card is full, the reward is ready. For example: buy 10 coffees, get the 11th free.
See how many customers have a card, how many stamps you gave today, and who is one stamp away from a reward.
Customers add the card to their Home Screen in one tap. It gets your name and your own icon, without anyone downloading an app.
When a customer says yes to notifications, you can write: “Fresh cinnamon rolls at 2pm.” One message a day, so nobody gets tired of you.
Customers are told when their reward is ready. You don’t have to do a thing.
Fresh cinnamon rolls today from 2pm 🥐
