Google Pay encrypts the newly tokenized card and it is ready to be used for payments. To make a purchase, a customer taps their mobile device on a point-of-sale terminal or chooses to pay in your mobile app. Google Pay responds with the customer's tokenized card and a cryptogram which acts as a one-time-use password.

How do I use Google Pay?
