Google Pay

Google Pay™ is a payment service provided by Google and is a convenient, efficient and secure way for customers to pay in mobile apps and on websites using their Google Account. Google Pay gives you access to hundreds of millions of cards saved to Google Accounts worldwide.

When your customer chooses Google Pay, a Payment Sheet will be displayed, which lists the goods or services, payment methods saved to their Google Account, plus other optional fields such as shipping address and additional information. The customer can then quickly review the purchase, select a payment method, add an optional shipping address and confirm the payment. See the videos in Start using Google Pay today for more detail.
