I tried it once and neither the salesperson nor I could find how to ask the app to read the merchant's QR code, so I gave up and paid cash.
It works only for NFC contactless ("tap") payments from your phone. Scanning a QR code won't work - US Google Pay uses a different format of QR codes to manage person-to-person payments, whereas the Indian Google Pay works with UPI QR codes and they are not compatible. When the merchant generated a QR code for you, that was for his UPI payment account.
