The old problem
The paper card has had its day. And it's costing you regulars.
Every cardboard punch card you hand out is a promise that the customer will return. But paper gets lost in a wallet, left at home, soaked, and sometimes over-stamped. You give away free coffees without knowing to whom, and you never know who's one stamp from their reward.
- They get lost, and the customer starts over from zero.
- Stamps get faked with any old pen.
- You can't tell who's a regular or who stopped coming.
Stampi turns that stamp into something the customer never loses and you can always see.
Why ditch paper
Keeping customers pays more than chasing new ones

Restaurant industry data, 2025
Paper gets lost, leaves no data, and never tells you who came back. Stampi turns every stamp into a customer you can see, measure, and bring back.

Built by Emov Studio
Built by people who also hated losing the card
At Emov Studio we watched our favorite cafés hand out paper cards that customers lost, forgot, or faked. So we built Stampi: a loyalty stamp that lives in the phone, drops with a tap, and turns a first visit into a regular. Delightful for the customer, dead-simple for the shop.

Frequently asked questions
What every shop owner asks us before getting started.
Is it complicated to set up?
No. You build your card in the builder in about five minutes: set the reward, the stamps, and your logo. We hand you the NFC tag for your counter and you're ready to stamp.
See the step-by-step tutorialWill my customers actually use it?
Yes, because for them it's easier than paper: they just tap their phone. And they never lose the card, so they don't start over. The celebration on each stamp makes coming back feel good.
Do they need a phone with NFC?
Most modern phones already have NFC. For the ones that don't, there's a QR code fallback, so no customer is left out. And if the customer is not even at your shop, you can also give them the stamp remotely.
See how to give stamps remotelyIs it secure? Can stamps be faked?
Every stamp and redemption runs on codes that rotate every few seconds and are confirmed by your staff. Screenshots and pen tricks won't work.
How much does it cost?
We sort that out on WhatsApp based on the size of your business. Message us and we'll put together a clear proposal, no surprises.
What languages is the app in?
Spanish and English. Your customers pick whichever they prefer, perfect for Latin America and the diaspora.
Does it work with Google Wallet and Apple Wallet?
Yes. Your customers save the stamp card to Google Wallet or Apple Wallet and open it right from the home screen, no hunting through apps. Stamps still land with a tap of NFC.
What is a digital stamp card?
It's the phone version of the classic punch card: instead of paper that gets wet or lost, the customer collects stamps on their phone and gets the reward once it's full. You see who keeps coming back, all from one dashboard.
What kinds of businesses is Stampi for?
Any business that wants customers to come back: cafés, bakeries, ice-cream shops, juice bars, barbershops, salons, and restaurants. If you already give a free coffee or treat after so many purchases, Stampi makes it digital.
Can I use the same card across several locations?
Yes. Your customers earn and redeem stamps at all your locations with the same card, and you see each location's activity in the dashboard.
What customer data can I see?
You see how many members you have, how many stamps you give out, and how many rewards get redeemed, so you know who returns and how often. Only what you need to reward loyalty, with respect for your customers' privacy.
