A digital stamp card for coffee shops and bars

A digital stamp card for coffee shops is the phone version of the classic «10th coffee free» punch card. The customer shows their QR code and the barista adds the stamp in 3 seconds with their own phone. No paper, no cheating, and you know who comes back and how often.

How many stamps should a coffee shop loyalty card have?

  • Black coffee or latte: 8 to 10 stamps = 1 free coffee. This is the most common set-up, and customers complete it in 2 to 3 weeks.
  • Full breakfast: 6 to 8 stamps = 1 free breakfast.
  • Tapas bar or pub: 10 drinks or snacks = 1 free small plate or drink.

The key is that a regular should be able to complete the card in less than a month. Any longer and they forget about it.

Stamps or points in a coffee shop

Stamps. The spend is low and similar on every visit, so counting visits is simpler and more motivating than counting euros. If you also sell take-home products (coffee beans, cakes to order), you can combine it with a points card.

A worked example (illustrative)

Say you have 100 regulars who come in twice a week. A coffee sells for €1.50 and costs you €0.30. The card is «9 + 1 free».

Item Per month
Half an extra visit per customer per week (+50 coffees/week) +€300 in sales
Free coffees (≈28/week × €0.30) −€35
Socios Plus −€5.99
Result ≈ +€260

And that’s before counting the toast or pastry that goes with the coffee. Work out your own numbers with the return calculator.

Frequently asked questions

Do my customers have to pay for the app?

No. The Socios customer app is free forever. Only the business pays for Socios Plus, with a 14-day free trial and then €5.99 a month.

What if a customer doesn’t want to download anything?

With a clear poster and a free welcome stamp for signing up, most people download it on the spot: it takes less than a minute.

Can I run several cards at once?

Yes. For example, one stamp card for coffees and another for full breakfasts.

Does it work in bars and pubs?

Yes. You can give one stamp per drink or use a points card based on the amount spent if the bill varies a lot.
