Starting point

Paper stamp cards cost money, ran out — and forced a choice about who even got a card.

Treuly setup

Since the pilot phase, Studio HACO has been running a Treuly card with the reward “10th appointment −20%”.

Counter workflow

Guests add the card to Apple Wallet or Google Wallet. At the till, one scan is enough — no extra app for the customer.

Studio HACO is a hair salon in Hamburg and one of the first businesses using Treuly in day-to-day pilot work. Behind the glass on Grindelberg is the real rhythm: cuts, the desk, regulars — and since the pilot, a digital stamp card in the Wallet instead of paper stacks at reception.

What we tell here are only facts and photos the business has cleared for public use. Missing interview answers and metrics stay clearly open until approval lands.
