The card verification flow is used to verify the details of a user’s card. This is accomplished through the verifyCardWithMinimumReservation method. If this method synchronously returns SUCCESS it means that the user's card details have been verified.

Google will subsequently call the asynchronousCancelFundsReservation method in order to return any funds to the user that were reserved during the verifyCardWithMinimumReservation method.
