Telegram loyalty without an app
A café loyalty program that lives entirely in Telegram — stamps, rewards and customer broadcasts, with no POS, no hardware and no native app.
The problem
A café wanted loyalty stamps and customer broadcasts — without a POS system, special hardware, or a native app nobody installs.
How it works
- Customers join via Telegram and get a personal QR loyalty card.
- Staff scan the QR from any phone to add a stamp — no special hardware.
- After 7 stamps the next coffee is free, tracked automatically.
- The owner broadcasts promos and the menu to every customer in ~30 seconds.
Results
- 325+ active customers, zero app installs
- Loyalty and broadcasts with no POS or hardware
- Deploys for a new location in a day
- Bilingual broadcasts (RU + Hebrew)
