How to build customer loyalty in 2026: the merchant's guide

A local business lives on its regulars. The customer who walks through your door every week weighs far more over a year than a passer-by on a Saturday. Yet most marketing effort (local advertising, social media, events) aims at strangers, while the regulars receive nothing.

Recruiting a new customer means convincing them of everything: finding you, trying you, preferring you. Bringing back a customer already won asks only one thing: giving them a good reason to choose your address over another. That is exactly the role of a loyalty programme:

• More frequent visits: a card being filled up creates an appointment. A customer with 8 stamps out of 10 does not buy their bread elsewhere.
• A concentrated basket: rather than spreading their purchases across three addresses, the customer accumulates with you.
• Word of mouth: a reward received gets talked about, especially when the card lives in the phone and is easy to show.

Not all mechanics are equal. Here are the ones proven in local businesses:

• The stamp card: one visit, one stamp, a reward at the end. Simple and readable, perfect for the bakery, the café or the food truck, where baskets are similar.
• Points on the amount spent: 1 euro becomes 1 point. Fairer when bills vary a lot, as in a restaurant or a salon.
• The welcome bonus: giving 1 or 2 stamps at sign-up. A card already started is completed more often than a blank one; it is a well-documented motivation bias.
• The birthday gesture: an automatic reward on the day. Inexpensive, very memorable.
• Winning back inactive customers: a customer who has not returned for a few weeks gets a gentle message with an offer. It is the visit that slipped away coming back.

What these mechanics have in common: they reward a precise behaviour, and the customer understands the rule in one sentence.

The cardboard card has one merit: it exists. But it gets lost, forgotten at the bottom of a bag, faked with an obliging stamp, and above all it teaches you nothing: there is no way to know how many cards are circulating, who comes back, who has dropped off.

The digital loyalty card solves those three problems at once. It lives in Apple Wallet or Google Wallet, next to the bank card, so it is always in the customer's pocket. Every confirmed visit is counted, which finally gives you a real view of your loyal customers. And it can speak: the balance updates live, and your messages appear on the card.

Beware of one trap, however: solutions that require the customer to install a dedicated app. Nobody downloads an app per shop any more. The right approach is the wallet already present in the phone, with no installation at all.

Three developments make digital loyalty far more accessible than a few years ago:

• The wallet is already in the pocket: Apple Wallet is preinstalled on every iPhone, Google Wallet is on most Android phones. Your customers already use them to pay contactlessly or to travel.
• SMS has lost the argument: billed per message and felt to be intrusive, it gives way to notifications tied to the card, which cost nothing and stay in their place.
• Serious free plans exist: launching a programme no longer requires hardware, a subscription or a commitment. A merchant can test in real conditions without spending a euro.

Here is a simple method you can apply in a week:

• 1. Choose your mechanic. Similar baskets: stamps. Variable baskets: points. If in doubt, start with stamps, you can adjust later.
• 2. Calibrate the reward. It must be reachable by a regular in one to two months, and be appealing: a free product beats a token discount. The classic order of magnitude: roughly one visit free out of ten.
• 3. Make the card impossible to forget. A card in the phone rather than a piece of card, and a sign-up that takes one gesture: the customer scans a QR at the counter, once.
• 4. Bring the team on board. One standard sentence is enough: “Do you have our card? It is free, you just scan it, and you get a coffee after ten.” Offered at every payment, without exception.
• 5. Measure and adjust. After a month, look at three figures: sign-ups, second visits, rewards claimed. A threshold never reached should be lowered, a reward never claimed should be changed.

If you are starting from scratch, the simplest thing is to test with a free tool that carries no commitment. Digikart, a French solution, offers exactly that: a loyalty card in Apple Wallet and Google Wallet, with no app for the customer to install, free and with no cap on customers. The programme is set up in about fifteen minutes, counter poster included.

To dig deeper, the why Digikart page details the approach, and the FAQ answers the practical counter questions: phone compatibility, customers without smartphones, scanning time. Loyalty is not a gadget: it is a habit you install in your customers. The best time to start was a year ago; the second best time is this week.
