This is an official Google Pay extension built in collaboration with Unbound Commerce to provide merchants with the option to enable Google Pay as a checkout and payment option to their customers. Google Pay helps businesses around the world accept payments and increase conversions by enabling simpler, more secure checkout in your apps and on your websites. When you integrate with Google Pay, your customers can pay quickly using the payment methods they’ve securely saved to their Google Accounts. 

This extension for Magento 2, when configured, will display Google Pay as an option in the Mini-Cart as well as the standard checkout screens. Checkout with Google Pay is easy and fast, decreasing your customers’ time to buy, and increasing your conversion. There are no fees for merchants or customers to use Google Pay, and Google’s enhanced security and identity controls means Google Pay transactions are declined less frequently than card only transactions.
