What is Revolut Pay?
Revolut Pay is a custom payment method available to all Business customers who currently have been approved for a Revolut Merchant account.
Revolut Pay allows your customers to pay quickly and directly with their Revolut Personal accounts or by card (if they don't have a Revolut Personal account). All they have to do is click the "Revolut Pay" button, add the payment details if requested and confirm the payment.
