It will be nice to have the option to pay at stores and receive payments from others. Currently, PayPal and Venmo are doing a great job on this matter. This way there is no need to use Apple Pay, Google or Samsung Pay. All you need is Revolut app to make and receive payments. Revolut also can save the transaction feeds charged by Apple, Google and Samsung.
You can just create a QR code containing the https://revolut.me/username. I highly doubt that you will see that kind of payment option at your local merchant. Revolut Business isn’t nearly popular enough to be a universally accepted method of payment.
