To use contactless payments with Google Wallet, make sure your phone’s near field communication (NFC) is turned on in the settings. Open the Google Wallet app and set up a payment method for contactless transactions. Once your phone meets all the requirements, it’s ready to make contactless payments. To pay in a store, wake up and unlock your phone, hold the back of your device to the payment reader, and follow the on-screen instructions. You can also use different payment methods and return items purchased with contactless payments.
