For Prague businesses
A loyalty program for Prague, built in Prague
Czech customers already know the 10th-coffee-free card — and already carry tickets and boarding passes in their phone wallet. Stampit puts your stamp card in the same place: added with one QR scan, never forgotten in a drawer in Žižkov.

Running a shop in Prague is a loyalty problem
Ten alternatives within two blocks
Prague's center has one of the densest café and gastro scenes in Europe. When the shop next door is 40 metres away, the only durable edge is a reason to come back to yours specifically.
Tourists pass through, locals pay the rent
A visitor buys once and flies home. Your štamgasti — the regulars — carry the quiet months. A loyalty card is aimed squarely at them, and paper cards keep failing them.
Everyone has a paper card. Nobody has it on them
Czech customers have collected "10. káva zdarma" cards for years, so the habit exists — the cards just live in other jackets. A card that is always in the phone stands out by simply being there.
How it works, from Smíchov to your counter
Stampit is made by Innovai Labs in Prague — the counter flow was designed in the same cafés you compete with.
Set up your card once
Pick your logo, colors, stamp icon and reward in the Stampit dashboard. A working loyalty card takes about 15 minutes — in English or Czech, no developers needed.
Customers scan a QR code
One scan at the counter and the card lands in Apple Wallet or Google Wallet. No app install, no sign-up form — the same motion Prague customers already use for letenky and event tickets.
Staff stamp in one tap
Your team scans the pass with the Stampit Partners app or taps phones via NFC. Every employee has their own login, so stamps stay traceable across shifts and locations.
The numbers, in koruny
Take a flat white at 95 Kč. A 10-stamp card means a regular spends 855 Kč across nine visits to earn one 95 Kč drink — a reward worth about 10% of spend, which is the healthy ceiling, and it costs you ingredients, not the menu price.
A local who stops by three times a week finishes the card in roughly three weeks. Research on café stamp cards (Kivetz, Urminsky & Zheng, 2006) found customers speed up as the reward gets closer — the effect you want working for you, not for the café across the street.
The same shape works beyond coffee: a lunch bistro at 189 Kč per meal might run an 8-stamp card, a barbershop at 450 Kč per cut a 6-visit card. The rule of thumb: reachable in 4–8 typical visits, reward worth 5–10% of what the customer spent getting there.
You can change the card length, reward and earn rate any time in the dashboard — every card already in a wallet updates itself.
Built for how Prague shops actually run
Lives in the wallet app
Apple Wallet and Google Wallet — where Prague customers already keep tickets and boarding passes. Wallet habits here are mature; your card joins an existing routine.
No app, no sign-up
Customers join by scanning a QR code at the counter. No download, no account, no form — joining is faster than paying.
One card across your locations
Karlín, Vinohrady, Holešovice — stamps add up across every branch, and the dashboard shows how many regulars actually move between them.
Numbers instead of guesses
Cards issued, active cards, stamps given, rewards redeemed — per location, in one dashboard at partners.stampit.app. Finally see whether the program pays for itself.
Messages on the card itself
New menu, changed hours, a Friday event — push an update straight onto the pass in your customers' wallets, no email list required.
Support from the same city
Stampit is built by Innovai Labs in Prague. When you write to us, you reach people who know your market — in Czech or English, in your time zone.
Questions Prague businesses ask us
Does Stampit work for an English-speaking owner in Prague?
Yes. The dashboard, setup wizard and support are available in English, while your customers see the card in their own language. Many of our Prague partners are internationally run businesses serving a mostly Czech clientele.
Do my customers need to install an app?
No. The loyalty card is a pass in Apple Wallet or Google Wallet, added by scanning a QR code in a few seconds. An optional Stampit app exists for customers who want all their cards in one place, but it is never required.
Is anyone in Prague actually using this?
Yes — Cafe Tone, a specialty coffee business with three Prague locations in Karlín, Vinohrady and Holešovice, runs its loyalty program on Stampit with one shared card across all three shops. Stampit itself is built in Prague by Innovai Labs.
How does this square with GDPR?
Simply. A pass added by QR scan requires no sign-up form, so you collect minimal personal data — far less than a typical email-based loyalty scheme. Stampit is operated by Innovai Labs s.r.o., a Czech company, and processes data under EU rules.
My customers are used to paper stamp cards. Will they switch?
That habit is your advantage: Czech customers already understand "10. káva zdarma", so there is nothing to explain — only the format changes. Keep accepting paper for a transition month and transfer stamps when regulars bring their old cards in.
What does it cost?
Stampit starts with a free trial, and plans scale with your business — see the pricing page for current tiers. There is no long-term contract and no per-stamp fee.
