About tap and pay
When NFC is turned on, you can tap the back of your device to an NFC payment terminal to pay for your purchase.
If you have more than one payment app installed on your device, when you tap to pay for a purchase, you pay using the app
that is set as the default. You can change which app is used as the default. If you want to use another payment app for
some transactions, you can set the tap and pay feature to use the payment app that is open in the foreground instead.
