Pay With Your Phone - Huawei NEXUS 6P Quick Start Manual

Pay with your phone

When NFC is turned on, you can use Tap & pay to pay for items just by
holding your phone to the contactless terminal at checkout.
To manage which app you use for payment:
• Go to Settings > Device > Tap & pay > Payment default.
If you don't have a payment app on your device, such as Android Pay,
search Google Play for "payment apps." For more information, visit Tap &
pay with your device.
