Digital loyalty card: what it is and how to choose one for your shop (2026)
A digital loyalty card is the usual stamp or points card, kept on the customer's phone instead of in their wallet. It can be an app, a service with a login, or a pass in Apple Wallet or Google Wallet. For a small business, the biggest difference is whether the customer has to install anything.
In short
- There are three ways: a paper card, an app, or a pass in the phone's wallet (Apple Wallet or Google Wallet). The practical difference is what you ask of the customer: nothing, a download, or a QR scan.
- What makes a card work is its design (how many stamps, what reward, whether it starts with progress), not that it is digital. The format only changes what you lose, what you see and what it costs.
- Before choosing, check five things: what the customer must do, what happens on Android, how staff stamp, what data you see, and what happens if you cancel.
What exactly is a digital loyalty card?
It is the same mechanism as the cardboard card ("tenth coffee free") in a different format. The customer carries it on their phone, you add a stamp at each visit, and the reward shows up when it is full.
What changes is where the card lives:
- In an app. The customer downloads the shop's app, or an app that gathers many shops. It means installing something, and an app that gives no value gets deleted.
- In a web service with an account. The customer signs up with an email or phone number. Lighter than an app, but it still asks for details and a login or code.
- In the phone's wallet. The customer scans a QR code and the pass is saved to Apple Wallet or Google Wallet, with no app from the shop. Apple describes passes that can be added through an app, by email or on the web, without installing the related app. Google offers loyalty cards that can be offered through a website, email or SMS link.
Paper, app or phone wallet? A table to decide
This table is our own assessment, not a study: it sums up how the three options tend to behave in a neighbourhood shop. You weigh it against your own customers.
| Paper | App | Pass in the phone wallet | |
|---|---|---|---|
| What the customer does | Takes the card | Downloads, opens the app, sometimes signs up | Scans a QR and taps "add" |
| Lost or forgotten | Easily | Hard to lose, easy to delete | It is in the phone; they must remember to open it |
| Stamped without you seeing | Yes, with a pen or a stamp | Depends on the system | Depends on the system: ask how each stamp is validated |
| What you see | Nothing | Usually visit data | Usually visit data; ask which |
| Start-up cost | Printing | Fee or development | Monthly fee, usually no extra hardware |
| Where it wins | No tech, no fee, everyone knows how | If the programme already has your customers in it | No download, and it looks like your brand |
Paper still wins if you have few regulars, your team handles it well and you don't need to know who comes back. There is no need to switch for the sake of it.
Does a digital card work better than a paper one?
There are no independent studies comparing the two in small businesses, and be wary of the "X% of paper cards get lost" figures going around: nearly all come from vendors and don't point to a checkable source.
What has been studied is the design of stamp cards. A 2006 experiment in the Journal of Consumer Research took a task of eight steps and turned it into one of ten steps with two already done, and found that this gifted progress changed how much effort people put in; the authors call it the endowed progress effect (Nunes & Drèze, 2006; we could only read the abstract). The idea for your card: one that starts with a couple of stamps already on it feels different to the customer than an empty one. And you can do that on paper, in an app or in a wallet.
So the realistic advantage of digital is not that it "converts more" but three humbler things: it doesn't get lost at the bottom of a bag, a stamp is harder to fake, and you can see how many people come back.
What should I ask before choosing one?
Five questions, in this order:
- What does my customer have to do? Count the steps from seeing the sign to having the card. Every extra step loses people.
- What about Android? On iPhone, Apple Wallet is already installed. On Android, Google Wallet has its own sign-up flow; try the process yourself on a real Android phone before you commit.
- How do my staff stamp? Ask what staff do at the counter, how long a stamp takes and whether you need to buy hardware. Scanning usually takes a few seconds longer than a rubber stamp (a practical rule of thumb, not a measurement): if someone tells you otherwise, ask to see it.
- What do I see? Visits per customer, busy hours, rewards given. If the tool shows you nothing, only the format has changed.
- What happens if I cancel? Apple passes, for example, keep working on the customer's phone if the issuer's certificate expires, but new ones can't be signed and existing ones can't be updated. Ask what happens to your cards and your data if you stop paying or the provider closes.
And one question that works with any provider: can I try it free and cancel any time?
How do I design a card people want to finish?
Whatever the format, fill in this sheet first. It is a template to copy.
My card sheet
- Who I want to bring back: _______ (people who come once a month, not those who come every day)
- How often that person comes: _______ (weekly, every 4-6 weeks…)
- Stamps for the reward: _______ (completable in 1-2 months at their pace)
- Reward: _______ and what it costs me to make: _______ €
- Does it start with a stamp already on it? Yes / No
- What counts as a stamp: _______ (a purchase, a service, a minimum spend)
- How I avoid the extra stamp: _______ (always applied by someone on the team)
- How I'll know it works: _______ (for example, how many come back within 30 days)
Line 2 is the one most people skip: a ten-stamp card for someone who visits once a month takes ten months to finish. If your cycle is long (a barber, a nail studio), lower the number of stamps. Spanish-language templates are on our templates page.
What if I already run everything on paper?
Test without throwing anything away. Either of these shows whether digital adds anything for you:
- A three-week side-by-side test. Offer the digital card to whoever wants it, keep paper for the rest, and compare how many people in each group come back.
- Count how many paper cards you hand out and how many return. That number, yours alone, is worth more than any vendor statistic.
If you want to see what a pass in the phone wallet looks like, try the Vernos demo: you scan a QR code and see it on your phone.
Frequently asked questions
Do my customers need to download an app?
It depends on the tool. With the shop's own app or a multi-shop programme, yes. With a pass in Apple Wallet or Google Wallet there is no shop app to install: the customer scans a QR code and the pass is saved in the phone's wallet.
What about customers without a smartphone, or who don't want to use it?
There will always be some. If that's you, keep a paper card for them; your whole counter doesn't have to go digital at once.
How much does a digital loyalty card cost?
It varies a lot between providers and changes often, so we don't quote a figure: get the price in writing, and check whether there are limits on cards, customers or locations, and whether there is a free trial.
Can I use my customers' data to message them?
That is a separate topic. If you collect personal data, data-protection law applies (in Spain, the GDPR as enforced by the AEPD), and this is not legal advice: check with the data-protection authority or your adviser before sending marketing messages.
