They tap before ordering
Customers hold their phone near the tile. The first time, a small card pops up on their phone with their first stamp and an Add to Apple Wallet button. No app, no sign-up form.

A stamp lands
Every visit after that, the tile and their phone both show the new stamp, so they can see exactly how close they are.

The reward is ready
When the card is full, their phone tells them. The next tap on a later visit claims it, and the tile shows your staff "Claimed" with the time.
First visit: one tap, and the card goes in their Wallet
