Frequently asked questions

What is Kuppo?

A digital stamp card app for small businesses. A stamp card on your customer’s phone — no paper, no plastic.

How much does it cost?

Detailed pricing is coming soon. Getting started is free — write to us if you’re interested!

Do my customers need a separate app?

No! Kuppo is a PWA (Progressive Web App) that runs on any phone. There’s nothing to download from the App Store or Google Play.

How do my customers collect stamps?

They scan the QR code on your counter with their phone. The whole thing takes a second — no waiting, no hassle.

Is customer data handled securely?

Yes. GDPR-compliant data handling and encrypted storage. Your customers’ data is safe.

Why digital instead of a paper card?

It can’t get lost, nobody leaves it at home, and you get real data on your customers’ habits. Everybody wins.
