Stempelek

Stamp cards get lost, get wet, and always end up in your other jacket. Stampek turns them into digital cards on your phone—a café, barber, flower shop, and bakery all in one place, always with you.

HOW YOU COLLECT STAMPS
A Stempelek device sits at the checkout. You touch your phone to it, and the stamp instantly appears on your card. The staff doesn't click anything, scan anything, or enter your phone number—the line moves on. If you prefer, you can also show the device a code from the app.

NO REGISTRATION OR FORMS
Install and collect stamps instantly. No account, no email, no phone number. Want to protect your progress before you switch phones? Log in with Apple or Google—it's your choice, not a requirement.

WHAT YOU'LL FIND IN THE APP
• All cards on one screen, with visible progress toward your reward
• A card that's close to being full highlights so you know when it's time to stop by
• Rewards to be collected and a history of those already redeemed
• A map and search engine for locations participating in the program—including those you haven't visited yet
• Filter by category: cafes, restaurants, bars, bakeries, barbershops, salons, gyms, and more
• Location card with address, opening hours, photos, and links to Instagram and delivery
• Notifications when a reward is just a few stamps away or the location has something special
• Four color themes—light and dark—to choose from

CLAIMING YOUR REWARD
A complete set of stamps unlocks your reward. You show the code to the staff or collect it yourself by holding your phone close to the device. The reward is released from the card exactly once—no notebook at the register and no need to explain whether it's already been redeemed.

HONEST STAMPS
Each time you touch your phone generates a one-time, signed token that's verified on the server. No one will be able to add stamps at home, and yours won't disappear. If your local internet connection goes down, the stamp will be stored on your phone and synced automatically.

DO YOU HAVE YOUR OWN LOCATION? The same app has a manager panel—you do everything from your phone, without a separate system or team training:
• Set the reward, stamp threshold, opening hours, photos, and social media links
• See statistics: stamps received, returning customers, redeemed rewards, and pending cards
• Send notifications to customers who are close to a reward but haven't stopped by in a while
• Plan campaigns for customers with at least N stamps—for a free Tuesday or before the weekend
• Run multiple locations: a shared card for the entire chain or a separate card for each location. Details and launching the program: https://stempelek.app

REQUIREMENTS
To collect stamps, the app uses NFC and Bluetooth to connect to the device in the location. The map and location search work without these permissions.
