FAQ
If a user has multiple cards stored which does Google Pay use for a transaction?
Users choose which card to use as a default - this card is always displayed on their Google Pay home screen at the top with additional payment options and loyalty cards stacked below. If the default card is not accepted at a retailer, or the user wants to use another payment option for a particular transaction, the user may choose another card they have on file with Google Pay and tap their phone again.
