Android Developers Blog: What’s next for Google payment and loyalty experiences
Yesterday, we announced the Google Payment API, which lets people pay in app or online with any verified credit or debit card saved to their Google Account, via products like Google Play, Chrome and YouTube.
For users, the option to pay with Google means breezing through checkout without needing to remember and type multiple lines of payment details. You simply choose your preferred card, enter a security code or authenticate with your Android device, and check out.
