Stamp card for restaurants: build loyalty without discounts
A stamp card for a restaurant needs to be built differently than one for a café: your guests come less often, the bill is ten times higher, and nobody wants to turn their restaurant into a discount store. With the right mechanic, the card is still one of the cheapest ways to turn occasional guests into regulars. Here you get a concrete recommendation with sample calculation, tips for your staff, and the automations that fill your empty Tuesday nights.
Visit frequency and bill size in restaurants
A typical restaurant sees its good guests once or twice a month, some only every two months. The bill per person is between €20 and €40, per table quickly €60 to €120. That's a completely different pattern than in a café.
This leads to two rules. First: the card must be short, otherwise it never fills up. Second: the stamp belongs on the bill, not on the plate. If you follow these two rules, you get a program that pays for itself and still looks like appreciation, not a discount.
The advantage over paper is especially big in restaurants: you find out which guest hasn't been there for three months and can reach out directly. With paper cards you don't even know their name. You'll find the basics under Customer loyalty in food service: 15 ideas.
Mechanic recommendation: 5 stamps, a dessert or aperitif
For most restaurants we recommend:
- 5 stamps, one stamp per bill from €25
- Reward: dessert, appetizer, or aperitif of choice (cost of goods €1.50 to €2.50)
- Cooldown: one stamp per card per day
The sample calculation:
| Item | Amount |
|---|---|
| Average bill per transaction | €70.00 |
| Revenue over 5 stamps | €350.00 |
| Cost of goods for dessert or aperitif | approx. €2.00 |
| Effective discount | under 1% |
Less than one percent of revenue, and this guest visited you five times. No reservation portal, no advertising, and no delivery service works anywhere near as cheaply.
If you want a bigger reward, you can add a second tier: 5 stamps for the dessert, 10 for a main course up to €18. That keeps the quick win and gives regulars a goal. Which length fits which frequency is explained in How many stamps until the reward?.
Rolling out the stamp card: the stamp belongs on the bill
In a restaurant, your staff has the contact, not the register. So the rollout looks like this:
- QR code on the table or in the bill folder. The guest has time while waiting for food to set up the card. A sign by the door is good as backup, but the table is the main place.
- Stamp when processing payment. Whoever brings the bill asks: "Are you collecting stamps?" and scans the card on the guest's phone with their own smartphone. It takes as long as the card terminal.
- Everyone on staff has a scanner. Not just the owner. The team logs in with a PIN, and you see later who issued how many stamps.
- Redemption is a tap in the dashboard. Card shown as full, dessert brought, redeemed in the dashboard. No discussion, no paperwork.
Your team should have this down after two days. How this works without lengthy training is shown in Rolling out a digital stamp card with your team.
Automations that make the difference in restaurants
In restaurants, weeks pass between visits. The card alone won't keep the guest coming. The automations will:
Slow-day booster. Tuesday and Wednesday are half-empty in many restaurants. An automatic message "Tuesday: free aperitif for card holders" goes to all guests with marketing consent and costs you €2 per table that would otherwise have been empty.
Winning back inactive guests. Anyone who hasn't visited in 60 days gets a personal reminder with an extra stamp. The timeframe is longer in restaurants than in cafés, otherwise you annoy guests who just have a normal rhythm. More on this under Winning back inactive customers.
Birthday. The birthday dinner is the classic in restaurants. A free dessert or a bottle of water on the house almost always brings a table of several people. The message goes out automatically a few days beforehand.
Flash promotions. A last-minute table on Saturday, a themed evening that isn't fully booked: "3 tables still available today, free appetizer with reservation by 5 p.m." These time-limited promotions reach your regulars directly on their lock screen.
Common mistakes with stamp cards in restaurants
- Cards that are too long. 10 stamps with one visit a month means: the card fills in almost a year. Nobody sticks with it that long. Five is the right number to start.
- One stamp per person. A table of eight guests gets one stamp, not eight. Otherwise the program fills up after one family dinner.
- Discount instead of reward. "10 percent off your next bill" feels like a discount store and costs you more than a dessert. Experience beats percentages.
- No minimum bill. A coffee at the bar isn't a restaurant visit. €25 as a floor keeps your numbers clean.
- Card only at the register, not at the table. The guest often doesn't even see the register. The QR code needs to be where the guest sits.
- Reward not known by staff. If the server doesn't know what the guest gets, awkwardness happens. Explain once, put it in the dashboard, done.
Conclusion
A stamp card for a restaurant must be short, tied to the bill, and reward with an experience instead of percentages. 5 stamps from €25 bill, a dessert or aperitif as reward, and a QR code on the table are enough to start. The automations for slow weekdays, birthdays, and long-absent guests then do what no paper card can.
