Digital loyalty card for restaurants: the complete guide

Updated 2026-08-24

What is a digital loyalty card?

Definition and difference with plastic card

A digital loyalty card is a dematerialized loyalty program: the customer does not receive any physical support. Their card is stored in their smartphone — usually in Apple Wallet or Google Wallet — and it is linked to their identity at the time of registration. The merchant manages the program from a web dashboard: he defines the rewards, monitors the passages and triggers reminders.

The difference with a plastic card lies in three points. First, the support: nothing to print, nothing to distribute, nothing to replace. Then, the channel: a plastic card cannot contact a customer; a digital card comes with push notifications. Finally, the measure: a plastic card is silent, a digital card records each visit and each reward unlocked.

Concretely, with DimaCard, the customer adds their card to Apple Wallet or Google Wallet in one click from a QR code — without installing an application. On each visit, you scan its QR from a phone or tablet and the points (or stamps) are added instantly. It is the equivalent of the buffer, but counted, time-stamped and connected to a reminder channel.

Formats: QR code, Apple Wallet, Google Wallet, application

Not all digital loyalty cards are the same. There are four main families of formats, and they do not require the same effort from the customer or the merchant.

• The QR code card: the customer scans a QR displayed at the checkout to register, then presents their personal QR each time they pass. No download, works on any smartphone. It is the simplest format to deploy in restaurants, including for a dining team.
• Apple Wallet: on iPhone, the card is added to the phone's native wallet. It appears on the locked screen, is accessible in two gestures and can receive pass notifications (like a boarding pass). This is the most visible channel for customers equipped with iPhones.
• Google Wallet: the Android equivalent. Same logic: the card lives in the native wallet, with no app to install.
• The dedicated application: an app specific to the business, to download from a store. It offers maximum control but adds friction: the customer must agree to download an app for a simple loyalty program, and the merchant must maintain it.

The decisive point for a restaurant: the adoption rate. A dedicated application loses a share of customers at the download stage. A card that is added to the Wallet from a QR only requires a gesture. This is why DimaCard relies on the QR code and native Wallets – Apple and Google – rather than on its own application. For a complete overview of formats, see the solutions page.

Why restaurants are abandoning plastic cards

Printing costs and logistics

A plastic card has a unit cost, a design cost, a reprinting cost each time the offer changes, and a distribution logistics cost. With each new card, new order, new deadlines, new stock to manage. And if you change the program – new levels, new visual – all the previous stock goes into the trash.

The digital card eliminates these positions: support is generated on the fly, personalization is done from the dashboard, and an offer update is instantaneous, without reprinting. For a multi-establishment restaurant or a small chain, the logistics economy is even clearer: a single configuration serves all points of sale.

Loss of cards and abandonment of the program

This is the Achilles heel of the physical map. A customer loses his card, forgets to take it, or accumulates ten cards that he can no longer distinguish. Result: he is not recognized at the checkout, his points are lost, and he abandons the program. The physical card rewards those who keep it, not those who frequent your establishment.

The digital card solves this problem by construction: it is in the phone, the object that the customer always has with him. No cards to lose, no points to “leave at home”. Support is no longer a factor in abandonment. We detail this change in the plastic vs digital card comparison.

Measurement: attendance and basket data

A plastic card tells you nothing: you don't know who is coming back, nor how often, nor what rewards are actually used. You are piloting your loyalty blindly.

A digital card records each passage, each point credited, each reward unlocked. You know which customers return, which leave, and which level triggers the most engagement. It's the difference between "I feel like this works" and "I know what works." Examples of business use by business are presented on the use cases page.

How a digital loyalty card works (step by step)

Customer registration (QR scan / form)

Registration is the step that decides everything. The shorter it is, the higher the adoption rate. The smoothest route: a QR code displayed at the checkout or on the table. The customer scans it, possibly enters a few fields (first name, email or telephone), and their card is added to Apple Wallet or Google Wallet in one click. No applications to install, no accounts to create on the client side.

Practical tip: Place the QR where the customer is waiting — near the cash register, on the dessert card rack, on the receipt. And train your team on a simple sentence: “You want to collect points? Scan this QR, it's in ten seconds. »

Accumulation of points and stamps on each pass

Two logics coexist: counting per visit (one stamp per visit, independent of the amount) and counting per expenditure (points proportional to the ticket). The first is simple and rewarding; the second rewards big baskets more. DimaCard supports both: you set the program according to your objective — to fill Tuesday evening hunger pangs or enhance the table that has an aperitif and dessert.

The gesture in the room remains the same as for a stamp: when paying, you scan the customer's QR from a phone or tablet. The points are added instantly, and the customer sees their balance change in their Wallet. With cashier integration (Square, or an API key for other systems), the crediting of points can even be automatic, without any additional action in service.

Rewards and Tiers

The program is only as good as its rewards. The most effective levels in restaurants are concrete and achievable: the 10th coffee offered, the homemade dessert after X points, a discount at a VIP level. The classic mistake is to place the first reward too far away: a customer who never reaches their first gift drops out.

The digital card allows you to adjust these levels continuously, without reprinting anything. You can also segment: a “regular” level for lunchtime customers, a higher level for evening customers. The DimaCard dashboard lets you configure rewards and thresholds freely, from the admin panel.

Sponsorship: transform a customer into an ambassador

A satisfied customer is your best salesperson — as long as you give them a tool. Integrated sponsorship allows an existing customer to invite a loved one and receive a reward when they make their first visit. Word of mouth, which is already the primary acquisition channel in catering, thus becomes measurable and rewarded.

For the restaurant, the interest is twofold: the acquisition costs less than an advertising campaign, and the sponsored customer arrives with a trusted recommendation. Sponsorship is part of DimaCard's native functionality — it is activated without development. To go further on the affiliation angle, see the affiliate program.

Push notifications: relaunch without spamming

This is the function that changes the economy of the program. A plastic card cannot tell the customer “we haven’t seen you in three weeks”. A digital card, yes. Push notifications appear on the phone's locked screen and, unlike SMS, they are not charged for sending.

The key is relevance, not volume. Three scenarios are enough to get you off to a good start: the reminder of inactivity (a customer absent for 21 days), the birthday (a free dessert), and the occasional announcement (a happy hour, a new dish). With DimaCard, these shipments are unlimited and free, included in the subscription, and you program them once so that they run automatically — without bombarding the customer, since only customers who have accepted the notifications receive them.

The concrete benefits for a restaurant

Increased visit frequency

The first lever of a restaurant is not to attract more customers, it is to bring back those who have already come. A customer who has points in progress and a reward nearby has an objective reason to come back to you rather than trying the establishment across the street. Automatic reminders – inactivity, birthday – transform this latent reason into an effective visit.

This is the basic mechanism of loyalty: reducing the interval between two visits. A regular who comes twice a month instead of once, that's potentially double the figure on their account, without an additional euro of advertising.

Average basket and additional sales

Loyalty is not only used to bring people back: it also serves to increase the ticket price. A customer a few points from a level is inclined to complete their order — the dessert, the extra drink — to unlock their reward. Levels in value spent, rather than in simple number of visits, amplify this effect.

Concretely: if your “free dessert” level is at €100 cumulatively, the customer who is at €88 has an immediate incentive to take the extra. It's additional sales, but driven by the program and not by pressure from a server.

Collection of customer data (in compliance with GDPR)

Each recorded passage is data: who comes, when, how much he spends, what rewards he uses. This data allows you to better understand your real customer base — not the one you imagine — and to adjust offers, hours and promotions. You discover, for example, that your Tuesday lunchtime customers are more sensitive to a discount, while those on Friday evening react to an event.

An important clarification: this data belongs to the merchant, not to the platform. With DimaCard, the customer file can be exported at any time (CSV), and you keep control of your database. Compliance with the GDPR is covered in the following section.

Digital loyalty card and GDPR: what you need to know

Data collected and purpose

A loyalty program processes personal data: at least an identifier (name, email or telephone) and a visit history. The GDPR imposes a simple principle: only collect what is necessary, and for a specific purpose. You don't need the date of birth to manage loyalty points - unless you use the birthday as a stimulus lever.

The golden rule: define the purpose before collecting. “Manage the loyalty program and send offers to customers who have accepted it” is a clear goal. “See what we can do with it later” is not one of them.

Consent and right of access/deletion

The customer must be informed of what you do with their data and, for marketing uses such as notifications, give their consent. This is also integrated into the product: only customers who have accepted notifications receive them. The customer also has a right of access and deletion: he can request the export or deletion of his data.

For the merchant, the good news is that compliance is not a technical project: DimaCard provides the tools for exporting and deleting data in accordance with the GDPR. The point of vigilance remains transparency: a clear statement at the time of registration, and an up-to-date confidentiality policy. Our privacy policy page details the framework.

How to choose your digital loyalty solution

Selection criteria (ease, wallet, sponsorship, price)

Faced with market offers, five criteria make the difference for a restaurant:

• Customer friction: should the customer download an app, or simply scan a QR? The lower the friction, the higher the adoption rate.
• The reminder channel: are notifications included or billed upon sending? A cost per message changes your ability to follow up regularly.
• The native Wallet: does the card live in Apple Wallet and Google Wallet? This is where the customer will see it, without opening an app.
• Sponsorship: is it integrated, or is a separate tool needed?
• The price and commitment: clear price, cancellable, without equipment to buy or technician to come.

The DimaCard price list is deliberately legible: three public levels – Standard €39 including tax/month, Premium €59/month, Pro €99/month – with a 20% reduction in annual billing and possible termination at any time. All the features are detailed on the solutions page.

Mistakes to avoid

• Choose an app that no one will install. Downloading a dedicated application is the first barrier to adoption in restaurants.
• Place the first reward too far away. A customer who never reaches their first level does not come back “for the points”.
• Spam. Sending one notification per day is the best way to encourage the customer to deactivate them. Program relevant scenarios, not a continuous flow.
• Neglect the data. A program without passage tracking or customer file export is a plastic card in disguise.
• Forget about compliance. Collecting without purpose or consent exposes you to sanctions and a loss of trust.

Conclusion

The digital loyalty card is not a modernization gadget: it is the transition from imposed loyalty to managed loyalty. Where the plastic card rewarded chance, the digital card rewards regularity — and finally gives you the means to contact your customers between two visits.
