This feature manages payment apps. The Tap & pay option does not apply to Android Beam and won't include certain apps, such as money transfer apps.
When NFC is turned on, you can use the tap & pay feature to pay for items just by touching your phone to a reader at a checkout register. If your device does not have a payment app, you can browse Google Play for payment apps.
Tap Settings then tap Tap & Pay .
All activated wallets are added under "Tap & pay".
If multiple wallets are activated, a user can at any point change the default by going to "Tap & pay" and update selection.
