A digital loyalty card for your café or coffee bar

A coffee bar lives on repeat visits. The same people come in four or five times a week, spend three or four euros, and walk past two other coffee places to get to you. That makes loyalty less about one big reward and more about giving them a small reason to keep choosing your counter over the one by the metro exit. A paper card in a wallet full of other paper cards rarely does that; a card that sits next to their boarding passes and Bancontact card in their phone has a better chance.

What to reward, and after how many stamps?

Coffee is the obvious reward, and it works because the cost to you is low while the value to the customer is the full menu price.

• 10Free coffee of your choiceThe classic. Lets them pick the oat flat white, not just an espresso.
• 8Coffee and a croissantFeels generous, still cheap: the pastry is the visible part.
• 4Free size upgradeA quick early win for new regulars.
• 15A bag of your house beansFor cafés that roast or sell retail coffee.

Here is an example of the maths. Say a flat white sells for €3.80 and costs you about €0.70 in beans, milk and cup. After 10 paid visits the customer has spent €38. The free coffee costs you €0.70, under 2 % of what they spent. Even if you count the full €3.80 as lost revenue, it is 10 %, and most of that customer’s ten visits might have gone elsewhere without the card.

A card can have between 3 and 30 stamps. Start with 8 or 10; if it feels too slow or too fast after a few months, change it. Only new cards get the new rule, so nobody halfway through loses their progress. You can also give one welcome stamp when someone joins, which makes the first card feel already started.

Which card type fits a café?

The stamp card is the natural fit, and it is included in Essential. One stamp per visit, a free coffee at the end.

On Pro, two other types make sense for coffee:

• Pack card. Sell 10 coffees paid up front, which suits office workers and students who pass every morning. The card shows “Not active yet · pay at the counter” until staff tap Activate, then staff tap Use 1 for each coffee. When the pack runs out, Sell a pack adds another. You are holding the customer’s money, so check gift-card and prepaid rules with your accountant.
• Points. Useful if you also do brunch or lunch and a basket can jump from €3 to €25. Staff type the amount on a till-style pad and the customer earns points per euro.

Pro also lets you run several cards at once, for example a stamp card for coffee and a pack card for the 10-coffee regulars. The join page shows a picker. VIP levels by number of visits can mark your daily regulars, shown on the pass and on the scanner.

How does stamping work during the rush?

The morning rush in a Brussels coffee bar runs roughly 7:30 to 9:30, mostly takeaway, mostly paid by Bancontact contactless. The scan has to fit inside that flow, not add to it.

Put the scanner phone or tablet on a stand next to the till. The person who takes payment scans the customer’s pass while the milk is steaming. The screen shows a big “+1” and the customer’s first name with progress, for example “Sarah · 4/10”, so you can greet them by name, which matters more on a busy morning than people admit. The pass on their phone updates within seconds.

If your baristas share one counter phone, each one logs in with a PIN. Every stamp records who scanned it, on which device and at which location.

Some practical points:

• Groups and second cups. The cooldown between two stamps on the same card is 5 minutes by default, so a colleague cannot get two stamps by ordering two coffees in one go. If you prefer stamping per cup rather than per visit, you can shorten the cooldown. Decide your rule and tell your team.
• Mistakes. A barista cannot undo a scan; the owner or a manager corrects the card in the dashboard with Adjust stamps, and the reason and who made the change are logged.
• Reward day. When the card is full, the pass shows “reward ready” and the customer gets a lock-screen notification. At the counter, staff tap Claim + add today’s stamp, so the free coffee is handed over and card 2 starts with today’s visit.

Seasonal and occasion ideas

• January: back to the office after the holidays. A push about a new winter drink reminds regulars that you are open again.
• Exam periods (January, June): students who camp at your tables with a laptop. Give them a reason to come back for a second coffee.
• Spring and terrace season: first iced coffee of the year, terrace open.
• September rentrée: offices and universities fill up again. A good moment to put the QR stand front and centre and sign up new regulars.
• December: winter drinks, speculoos latte, and gift ideas such as a pack card sold as a present.

What to send by push or e-mail

Push messages are a Pro feature. They appear on the lock screen through the wallet pass and only reach customers who ticked the box to receive your news. Keep it to one or two a month; a café that pushes every day gets its card deleted.

Example push messages:

• Title: “Rainy Monday?” Text: “Second cup is on us until 11:00. Show your card at the counter.”
• Title: “Iced coffee is back” Text: “Cold brew and iced oat latte are on the menu from today. Terrace open when the sun is out.”
• Title: “Your free coffee is waiting” Text: “You have a full card. Drop by this week and pick any coffee on the menu.” Send it to the “reward waiting” audience only.

E-mail idea: a short message to customers not seen in 30 days, sent automatically from your shop’s own address, with a photo of the new seasonal drink. Replies land in an inbox in your dashboard.

Common objections

“My regulars already know me.” Some do. The card is for the people you don’t know by name yet: the new office down the street, the student who comes twice a week. The scanner shows their first name, which helps you get to know them.

“It will slow down the queue.” The scan is one move with the phone, while they tap their card on the terminal. Customers join on their own by scanning the QR stand while they wait, so staff don’t fill anything in.

“I already have a paper card.” Keep both for a while. When a customer switches, a manager can add the stamps they already have on paper with a correction and a reason.

“My customers won’t download an app.” They don’t have to. The card goes into Apple Wallet or Google Wallet, or opens as a web card if they have neither. They type a first name and an e-mail, nothing else.

What does it cost?

Essential costs €29 a month excl. VAT: one location, one stamp card, unlimited customers and scans, the scanner for your whole team and your first QR stand included. Most cafés can start there. Pro, at €59 a month, adds pack cards, push messages and several cards at once, and you can try it free for 14 days. In Belgium the first merchants can lock in Pro at €19 a month for life.

If you also sell bread and pastries in the morning, the bakery page covers mixed baskets, and the restaurant page covers lunch service.
