The phone is already out when it’s time to pay. The card is easier to find than a piece of cardboard tucked into a wallet, a pocket or a bag, and its QR code displays even without a network.

Digital loyalty card: how to switch from a paper card to Wallet
The cardboard stamp card has long been the loyalty tool of local businesses, and for good reason: everyone understands it, it costs a few cents to print, and you can hand one out in a second.
You know its limits, too. Cards left at home, cards lost, three half-filled cards for the same customer. And above all, no way to know who comes back, how often, or when a regular stopped coming.
A digital loyalty program solves these problems without asking customers to install one more app. Your business’s card goes into Apple Wallet on iPhone or Google Wallet on Android. It shows the stamps or points and the next reward, and you update it remotely.
Moving to Wallet doesn’t mean giving up the stamp card. You keep a mechanic your customers know by heart, and make it more convenient for them and easier for you to manage. Here is how to make the switch without losing your regulars.
Why the paper card hits its limits fast
A cardboard card still works for a very simple program. It becomes a problem as soon as you want to measure loyalty, personalize an offer or bring customers back.
- Easy to forget
- Customers have to remember it at every visit. If they left it at home, either the visit isn’t counted or they walk away with a new card, and their progress ends up scattered across several cards. In Wallet, the card stays in the phone, next to the bank card and the transit tickets: it is there when they pay.
- Progress you can’t see
- A cardboard card shows the stamps, nothing more. It doesn’t remind anyone of the next reward and can’t change once printed. A Wallet pass, by contrast, updates remotely: balance, next tier, program name, with nothing to reprint or redistribute.
- No usable data
- An anonymous card tells you nothing about how often someone visits, how long they have been coming, or who your regulars are. A digital program ties each card to a customer and keeps the history of their visits. You finally know who comes back, and who has disappeared.
Remote updating isn’t a vendor’s promise: it is how Apple and Google designed the passes in their wallets to work.
What is a Wallet loyalty card?
A Wallet loyalty card is a pass saved in the phone’s wallet. It carries the business’s logo and colors, the customer’s QR code, their stamps or points, the reward they are working toward, and the program rules.
On iPhone, a pass can be added from an app, an email or a web page. On Android, Google Wallet adds it through the flow the card issuer provides. With Cartia, that flow starts with your shop’s QR code. In both cases, customers create no account and no password, and install no app in your name.
On iPhone, the Wallet app comes with the phone. On Android, Google Wallet is already on some models and is a free download on the others, starting with Android 9.
You sometimes read “card installed in three seconds.” With us, it is closer to a minute: a scan, a short form (first name, last name, email, date of birth) and adding the card to Wallet. It is short, but it isn’t nothing, and you may as well tell your team.
What moving to Wallet changes, in practice
Replacing the cardboard with a pass doesn’t just change the medium. Four things shift, for the customer and for your team.
Sign-up that doesn’t hold up the register
All plans
Nobody has to dictate an email address at the counter anymore, and there are no cards to hand out. Customers scan the QR code and sign up on their own phone while the line keeps moving.
Progress that’s always current
All plans
The balance changes at every visit, and customers see their stamps and next reward without waiting to come back. Changing your logo or colors? Cards already issued follow: right away on the Pro and Business plans, at the next visit on the Free plan.
An extra direct channel
Pro and Business plans
A card update can come with a lock screen notification: a private sale to announce, a Thursday afternoon to fill. There is no cost per send and no SMS plan, and customers see it without opening any app.

Equipment
An ink stamp and cards to order
A QR code, and your phone’s browser to credit visits
Wallet doesn’t do the strategy for you. A program works first through a simple reward, a team that talks about it, a QR code people can see, and messages worth reading.
Switching from paper to digital in five steps
The migration should stay simple so it doesn’t disrupt your regulars. A short transition period beats a paper card scrapped overnight.
Decide what you want to achieve
More visits, a higher average basket, inactive customers to wake up, slow hours to fill, your best customers to reward? If your receipts look alike, count visits as stamps. If they vary a lot, points tied to the amount spent will be fairer.
Keep a rule people remember
Customers should understand in one sentence how they earn, what they earn, from when and for how long. “One visit = one stamp; on the eighth, a free croissant” beats any system with multipliers and exceptions.
Create the digital card
Your logo, your colors, the program name, the main reward and the essential rules. The promise should read at a glance: a loyalty card is not a miniature billboard.
Carry over the old cards
For a few weeks, offer to transfer paper progress: four stamps on the cardboard, four stamps credited to the digital card from the counter. Announce a reasonable end date for the old card, and stick to it.
Put the QR code in the right places
On the counter next to the payment terminal, on the check holder, on the receipt, on a poster near the register, on your website, in a newsletter. The best moment is still checkout: the customer has just had the experience and already has their phone in hand.
A change goes down better when it fits in one sentence. Train your team to say it, and write the same thing on the poster.
What your team says at the counter
“We’re switching to a digital card so you never lose your stamps again. We’ll take your current card and add it to your phone right now.”
What the poster near the register says
“Your loyalty card, now in your phone. Scan the QR code: it’s ready in a minute, with no app to install.”
Security and GDPR: what you really need to plan for
Apple Wallet and Google Wallet provide a safe infrastructure for storing and updating passes. That doesn’t make your program GDPR-compliant by itself: the controller of the data collected is the business owner, together with their provider according to the contract between them. France’s data protection authority, the CNIL, publishes a guideline on commercial management that spells out what to plan for. The GDPR applies in the European Union; if you operate elsewhere, check your local privacy law, but the checklist below is sound practice anywhere.
- Collect only what’s necessary
First name, last name, email, date of birth. No postal address or buying habits in exchange for ten stamps.
- Say why
Every field you ask for has a reason, and the customer knows it at the moment they fill it in.
- Name the controller
That’s you, the business owner. Your provider is a data processor, and your notices say so.
- Set a retention period
A customer who hasn’t visited in years shouldn’t stay in your file indefinitely.
- Protect access
Who on your team sees the customer file, on which devices and with which accounts.
- Let people exercise their rights
View, correct, delete: a request should get a simple and quick answer.
- Let people opt out of marketing
A simple way to stop receiving messages, without having to give up their card.
- Keep proof of consent
When it is required, you know when and how it was given.
By type of business
The same switch, whatever your business
Scan, fill in, add: the journey is the same from one business to the next. What changes is the mechanic to carry over and the moment you show the QR code:
- Bakery loyalty cardReceipts that look alike: one visit, one stamp, and a free croissant on the eighth.
- Coffee shop loyalty cardThe coffee punch card is the most forgotten of all: a card in the phone settles the question.
- Restaurant loyalty cardThe QR code on the check holder: customers sign up while you take payment.
- Hair salon loyalty cardBaskets that vary from one service to the next: points tied to the amount spent are fairer.
FAQ
Frequently asked questions
Do my customers have to download an app?
Not a Cartia app. On iPhone, the Wallet app comes with the phone. On Android, Google Wallet is already on some devices and is a free download on the others, starting with Android 9. The customer scans your QR code, fills in a short form and adds the card: about a minute, with no account and no password.
Can I keep a stamp-based program?
Yes. Going digital doesn’t force you to switch to points. You keep “one visit = one stamp” and only replace the cardboard with a card in the phone. Points based on the amount spent remain an option, useful when baskets vary a lot from one customer to the next.
Does the digital loyalty card work without an internet connection?
On the customer side, yes: once added, the card stays in the phone and its QR code displays even without a network. Signing up and updating the card, however, go through the network. On the business side, the counter on the Pro and Business plans keeps working offline: stamps are sent when the connection returns.
Do I need to connect Cartia to my point-of-sale system?
No. Cartia works alongside the register: you scan the card and confirm the visit, the stamps or the reward from the browser of a phone, tablet or computer. That flexibility has a trade-off: it is a manual step at checkout, and the solution doesn’t see the receipt or the products bought.
Can I still offer a paper card?
Yes. Keep a few cards for customers who don’t have a compatible smartphone or don’t want a mobile wallet. Going digital should make loyalty simpler, not exclude part of your customers. In practice, most businesses set an end date for the old card and keep a few paper ones for exceptions.
