Digital stamp card & loyalty program
Digital loyalty program for businesses and chains
Turn walk-in customers into loyal regulars.
For single locations, multi-site businesses and larger chains: Treuli connects receipt QR-code scans with points, rewards and a loyalty card that works across locations. No extra hardware, GDPR-compliant and ready in minutes.
Born at the counter
The paper punch card had its day
Treuli turns the receipt your till already prints into a loyalty program. No digging through wallets, no lost cards. And you finally see who keeps coming back.
Paper gets lost
Crumpled, washed out, forgotten at home. And the card never tells you who your regulars actually are.
Your receipt can already do this
Your suitably configured till can print the TSE/RKSV QR directly on the receipt. Your customers scan it with their phone. When cryptographic verification is enabled, Treuli verifies supported receipt signatures before crediting points. That's all that happens at the counter.
Points add up on their own
€7 becomes 70 points, credited right after the scan. You decide how much a euro is worth.

How it works
For your customers: scan, collect, redeem
Four steps, in the browser and in the app alike. This is what Treuli looks like on your customers' phones, with your logo and your colors.
And for you
Ready in 3 steps
From sign-up to the first QR code. No IT knowledge, no outside help needed.
Register
Create an account and get going straight away. The Free plan costs nothing and you need no credit card.
Set up
Upload your logo, pick your colors, create two or three rewards, register your POS.
Let's go
Your POS already prints the QR codes on receipts via TSE/RKSV. Treuli now recognizes them as yours. Customers scan, collect, come back.
All the tools
Everything in there so your program actually runs
Not more, not less. What cafés, salons and shops really need.
Points via QR Code
Your POS's QR codes (TSE in Germany, RKSV in Austria) are recognized by Treuli after a one-time registration. Customers scan, get points. Works in the browser, and in the Treuli app if they prefer.
Rewards System
Discounts, free coffee, vouchers. You decide what your customers can redeem.
Referral Program
Every customer gets their own link. Share it and both sides get points.
Detailed Statistics
Who comes regularly, which rewards are going out, how many points are in circulation? It's all in the dashboard.
Campaigns & Newsletter
Emails to all customers or to specific groups. Plus in-app messages for promotions.
Products & Prices
Menu, product catalog or a list of your services via QR code. Change a price and everyone sees it right away. No print shop.
Apple & Google Wallet
The loyalty card moves into the wallet on the phone. It sits right next to train tickets and boarding passes.
Push notifications
Your promotions appear right on the lock screen. Every customer decides for themselves whether they want that.
Appointment Booking
Your own booking page with services, staff and calendar. Automatic email reminders to cut no-shows.

- The loyalty card sits in the phone and never gets left at home.
- Your offers arrive on the phone as a notification, and how many you send per month depends on your plan.

Frequent questions
Answered briefly
What shop owners ask us most often. Straight answers.
No. Your till already prints the required QR codes on every receipt (TSE in Germany, RKSV in Austria), and your customers use their own smartphones. No tablet, no scanner, no terminal.
No. Treuli is till-independent: it uses the QR codes your till prints anyway. No interface, no POS technician, no change to your routine.
Practically none in day-to-day business: points are credited automatically when customers scan. Only when someone redeems a reward do you confirm it briefly. The rest runs in the background.
Nothing. The QR code on your counter leads straight into the browser: scan, collect points, done. Anyone who wants it more convenient downloads the Treuli app for iPhone or Android, or puts the card into Apple or Google Wallet.
Treuli is hosted in Germany and GDPR compliant. Your customers' data stays yours. It is never sold on and can be exported or deleted at any time.
The Free plan costs nothing, permanently: up to 10 customers collect points, no credit card and no subscription. Once your regulars outgrow that, Starter is €39 a month and holds 250 customers. Starter and Business come with 14 days to try them, cancel monthly.
