Digital stamp card for cafés: Give regulars a reason to return

Make yours the regular coffee stop

The morning cappuccino, the lunchtime flat white: give customers a reason to keep their coffee routine with you. Your digital café loyalty card turns each paid coffee into progress towards a treat. It stays on their phone, ready for the next order.

Where the QR code belongs in a café

The till is the wrong moment for a form: your customer is holding their wallet and three people are waiting behind them. Put the code where people already wait: at the pick-up point beside the espresso machine, by the sugar station and on the tables for those who stay.

Scan, enter name and date of birth, add: that fits into the time it takes to steam the milk. If they have already paid, scan the new pass once at pick-up. Today’s coffee then counts and the card doesn’t start empty. For the code itself, see print your counter QR.

The morning rush: who stamps and when

Between eight and nine, your team decides whether they like this card. These rules keep the queue moving:

• The scan belongs at the till. Whoever is on the machine stays there. The person on the till scans while taking payment. Everyone on the team signs in to the app with their own QR login.
• Card first, then the reader. Ask as you ring it up: “Got your card?” Anyone who wants to show it then has it open before the terminal starts.
• Agree office rounds in advance. If someone buys four coffees and you count per coffee, that’s four scans. The app rejects a second scan within five seconds as a double scan. If that’s too slow in a rush, make it one stamp per order, and say so from day one.
• Full card, long queue. Scanning a full card doesn’t redeem the reward automatically. Your team asks quickly and can choose Belohnung aufbewahren & neuer Stempel (save the reward and add a stamp). Your customer carries on collecting.
• Poor signal in the basement. Stamps wait in a queue and are added later. Only redeeming needs a connection.

Which stamp count suits your café

Ten stamps is the familiar size, but it doesn’t suit every shop. Work from how often your regulars come in:

• Commuter bar, every weekday: ten stamps fill in about two weeks.
• Neighbourhood café, two or three times a week: ten stamps take around four weeks.
• Brunch spot, once a week: ten stamps take ten weeks. Six is often the more honest choice here.

The reward should be clear on first reading. “A coffee on the house” raises questions at the counter: does that include the large oat latte? Put it in the reward text, for example “Any hot drink”. If a pastry suits your menu better, that works too. For the reasoning, see a stamp count that fits your business.

Worked example: what does the free coffee cost?

The figures below are example numbers, not measurements. Use your own.

• Cappuccino selling price including VAT: €3.20
• Cost of beans, milk and cup: €0.70
• Gross profit per coffee, before staff and rent: €2.50

Ten paid coffees bring in €32 of net revenue and €25 of gross profit. The reward costs you €0.70 in ingredients. If your customer would have paid for that eleventh coffee anyway, you forgo €3.20 instead. That is the honest upper limit.

The Start plan costs €7.99 a month including VAT. At €2.50 gross profit, four extra coffees a month cover it. Nobody can promise you in advance that those coffees will come. From Start, the customer list shows you who returns.

What to say at the counter

One sentence is enough, as long as it fits the moment:

• To the customer you see every morning: “After ten coffees, the next one is on us. Scan here to get your card.”
• While the machine runs: “Fancy a quick scan? The card will be on your phone before your coffee’s ready.”
• When someone asks about an app: “No Treubar app or Treubar account. The card goes into Apple Wallet or Google Wallet. Google Wallet needs a Google account and you may need to install the wallet app.”

See Google’s wallet setup guide for installation and account requirements.

Common café mistakes

• No rule for specials. Does the smoothie count? The tea? If the Saturday helper decides on the spot, every customer gets a different answer. Stick the rule by the till.
• The code is only on the door. Nobody thinks about a loyalty card on the way in. It has to be where people wait.
• Launching into the Saturday rush. Practise the full route once on a quiet morning: get a card, stamp it, redeem it.
• A minimum gap that’s too strict. Anyone refused on a second visit at lunchtime will ask your team why. The minimum gap is off by default. Only set one if you have a reason.

Moving from paper to wallet

Your paper stack doesn’t have to vanish in a day. Pick a cut-off date. Until then both count; after that it’s the wallet card only. Keep honouring old cards so nobody loses anything.

To transfer stamps, from Start use Stempel anpassen (adjust stamps) in the customer’s profile. Admins and managers can do this, the Scanner role can’t. There’s no time for that in the morning rush. Take the paper card, note the name and add the stamps once things calm down. On Free, it’s easiest to let paper cards run out. Paper vs digital stamp cards covers the steps.

Which plan suits which café

Use Free to try it out with up to 20 customer passes among your most loyal customers. Start adds unlimited customer passes, the customer list and stamp log. With Pro, you can reach every cardholder by campaign, for example with two stamps on a quiet afternoon. Your team scans twice for that; a minimum gap, if you’ve set one, would reject the second scan. Apple Wallet shows a notification; Google Wallet displays the message in the card details.
