How a customer uses the stamp card
Step 1: The customer installs the app
From the app store or by scanning the QR code on your restaurant's materials. They can also join in the browser or by tapping an NFC card at the counter.
Step 2: The customer joins your loyalty program
By picking the restaurants they like in the app. They also join automatically with their first stamp or ticket purchase.
Step 3: The customer collects stamps on their phone
A stamp is given with an NFC card, a code or straight from the till. When the card is full, the reward is redeemed in the app at the counter.
Step 4: The data lands in your restaurant's register
Every visit, stamp and purchase builds your restaurant's own customer register, and you can use it in your marketing.

Paper or digital stamp card?
A paper stamp card has two problems: the customer forgets it at home or loses it, and the restaurant learns nothing from it.
You don't know who uses the cards, how often, or when they last visited. A full card is swapped for a reward, and that is the end of it. A digital stamp card does the same job but leaves a trail:
Stamps are stored safely on the customer's phone.
Everyone who collects a stamp joins your loyalty program, so your database grows with every stamp.
Partner Hub shows how many people use the card, how often, and when rewards are redeemed.
You can message card holders: remind them of a missing stamp, announce a new product or invite them to an event.
A card can have several reward levels, so collecting stays worthwhile after the first reward.
How are stamps given?
Customers join your loyalty program by scanning your QR code or tapping an NFC card with their phone. From then on, stamps collect in the app.
There are three ways to give a stamp, and you can use them side by side:
POS integration adds the stamp automatically from the purchase. The integration is available for the Restolution POS system, and you can set it up yourself in Partner Hub.
NFC card: the customer taps the Cluby Smart Card at the counter with their phone. The card is credit-card sized, and we ship it to your restaurant free of charge.
Code: staff give the stamp with a code, with no hardware and no integration.
Customers don't have to install the app: the stamp card also works in the browser. The app is always free for customers.
What does the stamp card cost?
Nothing extra – it is part of Cluby. Cluby is free for up to 100 members per restaurant. After that, pricing is based on member count and starts at €29 per month.
There is no setup fee and no long contract, and the NFC card and branded materials for your restaurant are included.
What kind of results can you expect?
When stamps collect on the phone, customers come back more often, spend more, and are in your loyalty database at the same time.
Kahvila Mutteri in Helsinki has used Cluby's stamp card since November 2023. Its coffee, salad and toast cards collect stamps straight from the till.
