Tip: After this step, you should get a message that your card was added and is ready to make contactless payments in stores, online, or in apps where Google Pay is accepted. If you get a different message, learn to fix a problem.
After you add a card, you might find a small transaction on your account from Google Wallet. This transaction checks that your card and account are valid. This transaction will soon disappear and doesn’t affect your balance.
