Turn first-time diners into regulars
Stamppi replaces paper stamp cards with a digital pass your customers carry on their phone. No app to download, no hardware to buy — just more repeat visits.
Built for cafés and lunch restaurants across Finland.
Loyalty, without the friction
Three steps. No POS integration, no new hardware, no plastic cards to print.
Set your reward
Choose how many stamps earn a free coffee, lunch, or treat. Change the rule whenever you like.
Customers collect
They show their code at the counter, you scan it, a stamp lands. Works on any phone — pay at the till as usual.
They come back
A reward waiting is a reason to return. Watch repeat visits climb in your dashboard.
Everything you need to bring people back
No hardware needed
Your existing phone or tablet is the scanner. Nothing to buy, mount, or maintain.
Nothing to download
A web app customers add to their home screen in one tap. No app store, no install friction.
Fraud-resistant
Rotating codes and server-verified stamps. Screenshots expire — no double-dipping, no cheating.
Live analytics
Stamps issued, active customers, rewards redeemed — broken down per location, in real time.
GDPR-native
Customer data hosted in the EU (Frankfurt). Privacy and consent built in, not bolted on.
