Hi, I’m thinking of creating an app that allows sellers to generate a QR code on their device (seller’s device). The buyer would scan the QR code on their device (buyer’s device) which would take them to a payment screen to complete payment, passing the necessary details in the URL.
The question I have is, would there be a way for the seller’s device to wait on the QR code screen and proceed to a confirmation screen once the buyer has completed the payment on their (buyer’s) device?
