As with Apple Pay, Samsung Pay, and almost every other payment app, Google Wallet doesn't transfer your actual credit card ...

Open the Google Wallet app. Tap on the Add to Wallet option, in the bottom-right corner. Hit New credit or debit card. Either scan your card using the camera, or select Or enter details manually.

Google Wallet and Samsung Wallet Do (Mostly) the Same Thing . These two apps, at their core, have the same core features.

Double tapping your Pixel's power button opens the camera by default, but now it can open your Wallet. Your choice!
