Every caf I love still hands me a paper card with a rubber stamp. I lose it. They lose me. The "solution" the industry sells them is a $100/mo POS bolt-on with its own customer app nobody downloads.

So I built the opposite: a loyalty stamp card that lives in the wallet your customers already have open Apple Wallet and Google Wallet. No app, no signup friction, no plastic. The merchant gets a dashboard, a QR code, and stamps land on the customer's phone in seconds.
