15% growth
in lunchtime visits
over 3,000 stamps
in the first few months
4 more restaurants
implemented the program
The Kolektiv group, which includes the Karlínská HolKa restaurant, had been considering introducing its own loyalty program. They were looking for a simple and effective solution that would fit into the fast-paced lunchtime rhythm of the Karlín business district and encourage guests to visit more often. They chose the PassMachine digital stamp card as a pilot project.
A simple solution for the lunchtime rush
The goal was to find a tool that would not complicate operations while delivering measurable results. The program was set up so that the digital stamp card works on a 4+1 free principle: collect four stamps and get the fifth lunch free.
The solution is simple, functional, fun, and actually a bit sexy – exactly what we need for our guests. The PassMachine team is fast, open, and willing to customize things, so we launched the program in a few days without complications.

Thanks to effective cooperation with the PassMachine team and their support, the implementation took only a few days. No complex training was needed for the staff, as the system is intuitive and easy to use. Employees quickly grasped its importance and actively offer it themselves.
Customers love the program
Customer feedback is very positive. Guests appreciate having the card conveniently in their mobile phones and perceive the entire program as a modern and fun element that turns lunch into a small game.

Great results and expansion to other establishments
The main goal of the loyalty program was to increase the frequency of repeat visits, and this has been achieved.
- Hundreds of guests joined the program.
- Over the first few months, they collected over 3,000 stamps and redeemed hundreds of rewards.
- Lunchtime attendance increased by more than 15%, and this growth is stable
Thanks to the successful pilot operation, the Kolektiv group decided to extend the digital stamp cards to four more establishments. Today, the program is operational in a total of five restaurants, three of which are in Prague and two in Uherské Hradiště.
Features used and future plans
Kolektiv uses the front of the cards for awarding stamps and the back for important information such as opening hours, contacts, or social media profiles. In the future, they plan to expand the benefits for customers and use the PassMachine card for direct communication with them. Guests have something to look forward to.
