Pay with Orrerie
One approval, from whatever coin your customer holds.
The first button on the checkout. It opens the Orrerie app with the order filled in.
The Orrerie app is in Google Play for Android, and invite-only on iPhone, not yet in the App Store.

The pictures on this page show the built product with a test business and simulated payments.
On a desktop too
Scan the code with the app.
On a phone the button opens the app. On a desktop the customer scans the code. The code holds only the checkout's number: the app fetches the order and shows its own review.
- The customer can pick any coin they hold.
- You receive the coin you keep: Relay delivers into your wallet.
- The customer's wallet address is screened against sanctions lists before the app is given the order.
Where store rules require it, Orrerie can switch the button off for a merchant; the checkout then shows any wallet only.

Review, approve, Paid
One approval, and the checkout follows.
After Face ID or a fingerprint the app pays from the customer's own wallet. The checkout shows the payment as seen and then Paid. No deposit address is shown on this route: the order is matched by the reservation the app made for it.
- Declined in the app: "Nothing was sent."
- Unknown after approval: "Don't pay again."
- Pay another way is always there.

Pay with Orrerie comes with your checkout.
People who use the Orrerie wallet pay you in one approval.
