A small shop prints a QR. Customers scan it, keep a stamp card in the browser, and collect stamps at the counter. Staff need one tap. You need no hardware.
01 / join. Scan the QR. The customer enters their phone number. That number is the card. No app, no password.
02 / stamp. Add the purchase. Staff tap once for what was just spent. That purchase becomes one stamp.
03 / redeem. Give the reward. A full card shows its QR. Staff scan it, confirm the reward, and the card starts again.
01
One QR on the counter. Customers open it with the camera already on their phone.
02
A phone number becomes the card. No app, no password, nothing to install.
03
Staff tap once for the purchase. A second scan in the same window is ignored.
