Google has been working on adding the smart home controls with NFC based card payments in the Power menu of Android 11. However, several users are reporting the availability of Google Pay on the first-generation Pixel running Android 10.
The redesigned menu shows some drastic changes. All the known shortcuts are resting at the bottom. With that much-given space, you will see all your wallet cards on the top. Just swipe left and right to see your cards, and select the one you want to use. Just like you see in the Google Pay app.
You can access a settings panel for the same on any Pixel device by starting “com.android.settings.Settings$GlobalActionsPanelSettingsActivity” using any activity launcher. However, most of the people will see a placeholder on activating it. This is available on Android 10 from the beta stage.
You may get this feature in the near future, given that Google is testing this feature with a handful of users right now.
