Google Pay is a payment method that helps you streamline the purchase process for your online store. For customers, Google Pay provides an easier and more secure way to buy items online using their payment credentials already saved to their Google Account, to speed through the checkout process.
When a customer pays for their order by using Google Pay, they don't need to manually enter their credit or debit card information or shipping address. The customer can tap the Google Pay button and Google Pay will provide that information to the payment provider.
