Poing is a digital loyalty app developed after seeing how often customers at the coffee bar lose their stamp cards or refused new ones due to paper waste. It began as a simple solution to a personal problem but grew into a loyalty platform for cafés and small businesses.
Using NFC technology, Poing recreates the tactile experience of stamping by tapping your phone with a stamp. Built during the Entrepreneurship minor at the University of Amsterdam, the app uses a subscription model — giving small businesses access to loyalty tools usually only available to large chains.
