Card verification flow

Overview
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.
