# What is a stamp card?

A poinz stamp card is the digital version of a classic physical stamp card.
Example: for every coffee you receive one stamp (stamp = poinz). Once you have collected 10 poinz, you get the 11th coffee for free.
After redeeming the stamp card, the collection starts again until you can secure the next reward.
