Hold it near.
That’s all.
There is only one action in the whole system, and it’s your customer who does it.
They hold their phone near the object on the counter
No download, no account to create, no password. An iPhone and an Android both read this object with no setup at all.
Their card lands in their wallet
In Apple Wallet or Google Wallet, next to their boarding pass. In your colours, with your logo.
On every visit, they hold it near again
A stamp is added. They have nothing to open: the card updates itself in their pocket.
After ten, they show you their card
You scan their code, you hand over the reward, the counter resets. That is the only moment you are involved.

A chip that signs
every visit.
The object on your counter holds a cryptographic chip. On every tap it produces a different signature, together with a counter that never runs backwards.
That is what lets us take every action away from the till without opening the door to fraud. Without that proof of presence, someone would have to validate. Which is exactly what we set out to remove.

Watch the card appear live.
On site or over video, you take out your phone, it takes a minute.
