If you see the option NFC or something similar, you can officially make payments in stores using Google Wallet. To add your card to Google Pay, select credit or debit card as your payment method, then take a photo of your card or enter your card information manually. You may need to tap 'More' to see other settings. If you don't see this option, look for a similar one like 'Connections' or 'NFC' for example. To find out if your Android phone supports Google Wallet in stores, open your device's Settings app and then tap 'More' under 'Wireless & networks'. Most modern Wear OS watches will have Google Wallet support, provided they have NFC built-in for contactless transactions.

With Wear OS watches, it's a similar situation. When you place your phone over a contactless payment terminal in a store, NFC and HCE work together to send your payment information to the store so you can make your purchase. However, to pay in stores using Google Pay, your phone must support NFC (near-field communication) and HCE (host card emulation). Google Wallet is available on all modern Android phones (Lollipop 5+).
