What Should Customers and Cashiers Each Do During a Counter QR Crypto Sale?

Why a counter QR sale has two screens

At a physical counter, the customer looks at a wallet app while your cashier looks at a terminal, tablet or phone. MiraclePay describes QR payments as useful precisely when the customer and merchant are viewing different screens. The merchant creates a payment for the exact order, the customer scans it with their own wallet, and staff see when the payment is confirmed.

What the cashier does

The cashier owns the sale amount and the status. They create the payment request for the exact order, show the QR code, and then watch the payment state on their own screen. MiraclePay's QR page lists the flow as create an order, display the QR, customer completes payment, and staff gets confirmation. The goods move only at that last step.

Other providers describe a similar split. BitPay's developer documentation says that in store you simply present the QR code to the customer. It also notes that the customer sees a confirmation on their device that the payment was sent, while the merchant side moves through its own statuses.

What the customer does

The customer scans the code with a wallet that supports the asset and network shown, then sends the exact amount. MiraclePay advises confirming wallet compatibility with the wallet's provider before a live payment. A short sign near the register can say this, so cashiers are not improvising technical explanations.

What to say when the phone and the screen disagree

A customer's phone showing that a payment was sent is not the same as your system showing it as confirmed. Give cashiers one calm line: thank you, we are waiting for our payment screen to confirm, and we will hand over your items as soon as it does. BitPay's documentation also warns that crypto transactions are irreversible once marked Complete, which is another reason to rely on the status rather than the customer's device.

Make the roles easy to practise

Run a few practice sales before opening: the cashier creates the request, a colleague plays the customer, and everyone rehearses the waiting line. Check your own provider's documentation for the exact status names your team will see, because they differ between providers and markets.

Before enabling live payments, confirm merchant transaction fees for your account configuration.
