The customer taps their phone
On the NFC plaque at your counter, or by scanning its QR code. A page in your shop's colours opens: first name, email, phone, that's all.

NFCNo app for your customers · card added in 30 seconds
The digital loyalty card that lives in your customers' Wallet. They tap their phone on the plaque and the card is added. You scan, the stamp is confirmed. No more paper cards.
The problem
They get lost, crumpled, forgotten at the bottom of a wallet. And you never really know who comes back.
How it works
Guided setup and onboarding (remotely or on site, depending on your area).
On the NFC plaque at your counter, or by scanning its QR code. A page in your shop's colours opens: first name, email, phone, that's all.

Apple Wallet on iPhone, Google Wallet on Android. No app to download, no password. The card sits right next to their bank card.

With the FidStar app on your phone. The customer's card updates by itself. Last box: the reward.

The FidStar NFC plaque
Our little difference: a real NFC plaque, made with our partner Tandem, sitting on your counter. Your customers don't even need to open their camera.
Features
Designed with shop owners, for the lunchtime rush as well as the quiet afternoon.
And this is just the beginning
New features arrive with updates, straight into your app, with no announced date. Here's what we're exploring:
The FidStar app
A real app for iPhone and Android, for you and your team. So simple it takes two minutes to explain.
Store release in progress.
Do the maths
Move the sliders with your real figures. An honest estimate, based on a cautious assumption.
Indicative simulation, not a promise: results depend on your shop, your reward and your customers.
Reliability and data
What others rarely mention, we made a priority: no lost stamps, no data lying around.
At the counter, only the first name and customer code are shown. No email, no phone: your customers sign up with confidence.
Every stamp and every reward is checked remotely. A reward can never be used twice.
Every action keeps its author, date and time. A cancellation always leaves a record.
Servers in the European Union, GDPR compliant. No resale, no ads, no tracking cookies.
Note visits on paper, add the stamps later from the app. Your customers lose nothing.
What your customers have earned stays earned, until their reward. Even if you change your settings.
Who is it for?
You freely set the number of stamps and the reward. A few ideas that work:
10 visits = 1 free baguette
8 meals = 1 free meal
10 coffees = 1 free coffee
6 cuts = 50% off the 7th
10 pizzas = 1 free pizza
5 treatments = 1 free set
10 burgers = 1 free dessert
8 visits = 20% off

Frequently asked questions
Another question? Just send a WhatsApp message, we reply the same day.
Message us on WhatsApp (new tab)No, never. The card is added to Apple Wallet (iPhone) or Google Wallet (Android), apps already on their phone. Only you and your team use the FidStar app to scan.
The QR code printed on the plaque opens exactly the same page. Any recent smartphone can scan it with its camera.
For two weeks, you use FidStar like a subscriber: the Wallet card, the plaque, the app, your team. No credit card required. Guided setup and onboarding (remotely or on site, depending on your area).
At the end of the 14 days, you choose the plan that suits you: monthly, yearly (2 months free) or multiple shops. During the trial, you're not committed to anything: if FidStar isn't right for you, you stop. If you continue, the subscription runs for 12 months (launch price guaranteed during that period) and the NFC plaque is billed €30, one-time. After 12 months, it's monthly, with no commitment.
You see the first name, customer code and card history, but not the email or phone. That's intentional: customers sign up more easily when they know their details won't be used for marketing.
The app shows “Service temporarily unavailable”. Note visits on paper, then add the stamps from your account once everything is back. Every manual addition is logged, with its reason.
Every stamp keeps the employee's name and the time. You set a maximum per customer per day, a delay between two scans, and you decide who can redeem a reward or add stamps manually.
Yes, anytime from the app. Cards already issued update automatically and stamps your customers have already earned are always kept.
During the 14-day trial, a simple email is enough, free of charge. Once subscribed, the subscription runs for 12 months; you request cancellation by email and it takes effect at the end of those 12 months. After that, it's monthly, with no commitment, cancellable anytime with 1 month's notice. The plaque stays with you and can be reactivated if you come back.
Yes. FidStar is updated regularly. Among the ideas we're exploring: messages to your customers on their card, multiple reward tiers, a points programme… They'll arrive with updates, with no announced date, straight into your app.
FidStar is designed and developed by Youssef Lahmer, founder of Yomax Group, a website and app studio. One single, reachable contact who sets up and supports every shop.
