What is a digital stamp card for döner shops?

A digital stamp card replaces the cardboard card at the counter: customers collect stamps via QR code or NFC, you see who regularly comes in for lunch and who hasn't been in for a while. No crumpled cardboard cards in pockets, no manual stamping during the rush, fully GDPR-compliant.

☕Mehmet's 10th döner. Today.

Mehmet orders his döner with extra chilli and ayran during his lunch break. He briefly holds his phone to the NFC card at the counter. No slip, no rummaging in his wallet.
“Congratulations! Your next döner is on us.”

The problem

Why don't guests come back?

Empty döner shop at lunchtime — symbol of missing walk-in customers
Murat runs a Döner Shop in Berlin. Ahmed came came every Thursday for his lunch break. Then they disappeared. Murat didn't notice – one lost regular = around €1,000 revenue per year simply gone.

How it works

3 steps to more loyal customers

1

Before the döner — 2 seconds to scan

Scan the QR code at the counter or hold the phone to the NFC tag — done. No account, no barrier. Works even when ten customers are queuing.

2

Rush hour doesn't stop the stamp

Stamps are credited instantly even in the packed lunch rush. You and your team do nothing — everything runs automatically, no one waits any longer.

3

At stamp 10: redeem a free döner

Whoever has 10 stamps can redeem their free döner directly — no slip, no asking. Or chips, ayran, whatever you decide. You set the rules, Stempely enables it automatically.

“We used to have cardboard cards that were constantly getting lost. With Stempely I can finally see which customers come regularly at lunchtime — and who needs a little reminder.”

Murat Y.

★★★★★

“Tuesday afternoon was always our weakest slot. Since we send a push at 4 pm, 15–20 regulars come in for dinner. Nobody expected that.”

FAQ

Frequently asked questions

Is a digital stamp card worth it given the tight margins in the döner business?+
Absolutely. A regular who comes 2–3× a week brings you around €900 in revenue per year. If you give away one free döner per 10, it costs you ~€3 food cost per free döner. The ratio is unbeatable. Stempely Premium costs 9,99 €/month — less than an ayran per week. A single win-back message that brings a regular back pays for Stempely for the entire year.
Does stamping work during the lunch rush when things need to move fast?+
Yes — stamping takes 3 seconds. The customer scans the QR code at the counter or taps their phone to the NFC card. You don't need to do anything, tap anything or confirm anything. The QR code works while you're building the next döner.
Do dürüm, lahmacun and pide count for stamps too?+
You decide completely. One stamp per visit regardless of what's ordered? No problem. Or only for certain products? Also possible. You configure the rules once in the dashboard — Stempely runs it automatically.
Can I promote lunch deals or evening specials via push?+
Yes, that's exactly what the push feature is for. Quiet Tuesday afternoon? Send a message at 4 pm to all regulars: "Döner deal until 7 pm — double stamps on every order." Straight to their phone, no WhatsApp, no flyer.
What does Stempely cost for my döner shop?+
You start for free — no credit card and no minimum term. The Premium package costs 9,99 €/month and includes all marketing features: push for lunch deals, win-back automation and contactless NFC stamps for the counter and order window. No contract, cancel monthly. With food costs of around €3 per free döner on every 10th order, Stempely usually pays for itself within the first month.
What does the first stamp process at the counter look like?+
At the first order the customer downloads the app — usually while waiting for their döner with yoghurt sauce, so under a minute. At the second visit they simply hold their phone briefly to the NFC card at the counter, no login, no typing, no phone number. Since the customer scans themselves, it doesn't hold up the lunch rush — even if five people are queuing at the same time.
What about customers who want to put their phone away while eating?+
That works fine: the stamp process takes less time than unwrapping the döner. In the typical döner shop target group (commuters, construction workers, students), the smartphone rate is practically 100% — anyone who doesn't have one or isn't on a mobile data plan gets the stamp on request from you with a click from the dashboard, without them having to give any details.
Is Stempely GDPR-compliant — even though I also take phone orders?+
Yes. Phone orders and the stamp card are separate: for the digital stamp card the customer leaves no data whatsoever — neither name nor phone number nor delivery address. You need no additional consent at the counter, no GDPR poster above the till and no data processing agreement for a newsletter tool, because Stempely sends no newsletters whatsoever. Your existing phone numbers for delivery remain untouched in your order system — the loyalty card needs none of that.
