You scan the card
Your customer shows the QR code on their card, you hold it up to the camera of your tablet or phone. Two coffees? Two stamps at once.
Digital stamp card for local shops
Stamp by stamp, a full card.
Your shop's stamp card, on your customer's phone. No app to install, no account, no cards vanishing in a coat pocket. You stamp with one tap, your customer watches it land.
Scroll on and the card fills up. Or tap it and stamp it yourself.
Why
A paper card works. Until it goes through the wash.
Lost, crumpled, forgotten
Half-full cards sit in wallets, coat pockets and the washing machine. Your customer starts over every time, and comes back less gladly.
A stamp is quickly given
A friendly colleague, a stamp left in a drawer, a card filled in at home. You never know what you are really giving away.
An app is a hurdle
Loyalty apps want a download, an account and an email address. Hardly anyone does that for a pastry.
How it works
At your counter in three steps
- 01
Your customer scans the poster
At your counter hangs a poster with a QR code. One scan and the card is on their phone: no app, no account, no name.
- 02
Tok: a stamp
With every purchase you scan the card on your counter tablet, or your customer types the code from your screen. The stamp lands on their phone straight away.
- 03
Full means reward
When the card is full, your customer gets a reward code. They show it at the counter, you redeem it with one tap. The card starts again.
Two ways to stamp
Choose what suits your counter
Your customer types the code
Your counter screen shows a six-digit code. Your customer types it on their card and gets the stamp. Handy when it's busy: you don't have to do a thing.
Who it's for
For the shops people come back to
The rewards below are examples. You choose how many stamps and what your customer gets for them.
Baker
After 10 loaves: a pastry of your choice.
Hairdresser
After 6 haircuts: the seventh at half price.
Chip shop
After 8 visits: a large portion of chips on the house.
Coffee bar
After 9 coffees: the tenth is on us.
Fair play
Hard to cheat, easy for your customer
A code works once
The code on your counter screen changes every 30 seconds, and as soon as it is used. Sending on a photo of your screen helps nobody.
A pause between two stamps
With the code, a card can get only one stamp per ten minutes (you choose the pause). At the counter you can still give two stamps for two coffees.
No guessing
Whoever tries too many wrong codes has to wait. Six digits that change every half minute can't be guessed.
A reward, once
Every reward has its own code that can be redeemed only once. Your counter sees at once whether it was already used.
Privacy
We don't know who your customers are
A card is a random number and a count. No name, no email address, no phone number, no location. So there is nothing to leak either.
Read how we handle data- No account and no app: the card lives in the phone's browser.
- No cookies and no trackers on your customer's card.
- A card unused for 18 months disappears by itself.
- Your customer can delete their card themselves, with one tap.
Questions
What shops ask us
Is your question not here? Mail contact@nealvdv.be and the maker himself will answer.
Do my customers have to install an app?
No. The card is a web page that stays on the phone. Whoever wants can put it among their apps with 'Add to home screen', but there's no need.
What if my customer gets a new phone?
The card has a button to move it: it makes a link your customer sends to themselves and opens on the new phone. Without that link a card can't be found again, because we don't know whose it is. That is the price of having no account.
What do I need at my counter?
A tablet or phone with a browser and, to scan, a camera. An old tablet will do. We pair the device with a one-time link; after that it stays paired.
Can I choose how many stamps and which reward?
Yes: from 3 to 20 stamps, a reward in your own words (in Dutch, French, English and German), your own card colour and the pause between two stamps with the code.
Does it work in French and German?
Yes. The card, the counter and this website are in Dutch, French, German and English. Your customer sees the card in their own language.
What if my internet goes down?
Your customer still sees their card, but stamping needs internet, on both sides. A phone with mobile data at the counter is enough.
Who's behind it
Made by nealvdv, not by a fintech
Stempelkaart is built and maintained by nealvdv, a web developer who makes websites and software for local businesses in Belgium. No investors who want your customer data later, no fees per stamp. You mail the maker himself.
