Stamp card for kebab and fast food: turning walk-ins into regulars
A stamp card for kebab shops and fast food turns the customer who walked by by chance into someone who comes back to you the next time they're hungry. Fast food has the perfect setup for this: high traffic, quick decisions, and customers already holding their phone while they wait. Here you'll find a mechanics model with sample calculation, the checkout workflow, and automations that fill your quiet Tuesday evenings.
Visit frequency and receipt value in fast food
Fast food is the industry with the biggest split between two customer groups. On one side: walk-in traffic. People from the train station, the office across the street, night owls. They come once and maybe never again. On the other side: your regulars. Tradespeople on lunch break, students, locals who come once a week, some more often.
The average receipt is €6–12, with a drink and sides sometimes €15. The decision is spontaneous. That's exactly why the stamp card works so well here: it turns "kebab somewhere" into "kebab at your place, I've got seven stamps left."
Recommended mechanics: 10 stamps, one free kebab
For kebab shops and fast food we recommend:
- 10 stamps, one stamp per purchase from €6
- Reward: one kebab, wrap, or dish up to €8 of customer's choice
- Cooldown: one stamp per customer per day
Sample calculation:
| Item | Amount |
|---|---|
| Average receipt per visit | €8.50 |
| Revenue across 10 stamps | €85.00 |
| Food cost for free kebab (meat, bread, salad, sauce) | approx. €2.50 |
| Effective discount | approx. 3% |
Three percent off the revenue from a customer who came ten times. Compare that to a single paper coupon "Two kebabs for the price of one" for new customers—that costs you fifty percent on the first visit.
If your shop mainly gets walk-in traffic, drop to 8 stamps. The card needs to fill up in a timeframe the customer can see: for weekly visitors that's two months, for every-other-week visitors it's already four. More on this in How many stamps until reward?.
Rolling out at the counter: set up while waiting, stamp at payment
In fast food, customers stand two to five minutes in front of the counter looking at their phone. That's your window:
- Display with QR code right at the counter. At eye level, where the customer waits. A second one on the wall behind the counter, large enough to scan from the line.
- The pitch during ordering. "Collecting stamps? Ten and you get one free." Short, clear, in every language your team speaks.
- Stamp at payment. Customer shows the card on their lock screen, your team scans with their phone. No stamp pad, no wet paper cards next to the salad.
- One phone at the register, permanently. An old smartphone with scanner access that stays at the till. Every employee logs in with their PIN.
The first stamp comes right when they set up the card. That's the moment they keep it instead of deleting it. For a fifteen-minute team briefing, see Rolling out digital stamp cards with your team.
Automations for kebab shops and fast food
Between lunch and evening, and on slow weekdays, the digital card's potential shines:
Slow-day booster. Tuesday and Wednesday evenings are quiet in many fast food shops. An automatic message "Today from 6 PM: bonus stamp on every kebab" lands as a Wallet notification on the lock screen of customers who opted in. Cost: zero. One extra stamp is cheaper than any discount.
Win-back campaigns. Someone who used to come weekly and has been gone three weeks probably found a new favorite. A reminder with two bonus stamps wins some back. Details in Winning back inactive customers.
Birthday. A free drink or side on their birthday is plenty for fast food. The customer comes, and usually not alone.
Flash deals for weather and events. Rain, street festival, game day: "Until 10 PM only: wrap plus drink for €8." Time-limited offers work especially well in fast food because hunger is spontaneous.
Multilingual cards. Many fast food shops serve customers from many countries. A card that appears in the phone's language lowers the barrier to signing up.
What to check in your dashboard after four weeks
After a month, look at two numbers: active cards and customers with at least three stamps. That second group is your real regulars; the rest was walk-in traffic trying it once.
If active cards are high but few customers get past three stamps, usually the cooldown is too strict or the minimum receipt too high for your menu. If both are low, it's the counter: the display isn't where the line waits, or the team isn't saying the pitch. Both are fixed in an afternoon.
Common stamp card mistakes in fast food
- Stamps with no minimum receipt. A €2 cola gets the same stamp as a €12 meal. €6 as a floor keeps the program clean.
- Reward too generous. "Any dish of your choice" brings the most expensive plate. A €8 cap or fixed selection keeps food cost in line.
- Display behind the counter. Customers can't scan what they can't reach. The code must be on the customer side.
- Only the owner stamps. If the owner is in the kitchen, nobody gets stamped. Everyone at the till needs access.
- Running paper cards in parallel. Two systems confuse the team and customers. Transfer old paper cards once, then digital only. Why paper fails in fast food is in Paper stamp cards vs. digital.
Takeaway
A stamp card for kebab shops and fast food turns walk-in traffic into regulars because it gives spontaneous hunger a direction. 10 stamps from €6 receipt, one free kebab up to €8, a display at the counter, and one pitch for the team—that's the whole setup. Automations for quiet evenings and lapsed customers run themselves after that. With stampa you can start free with up to 100 active cards, no credit card needed: Create your card now.
