In some cases, in order to ensure you're the card owner, we may ask you to confirm your card. If you see a "confirm credit card" link in the card details section of your PayPal Wallet, you'll need to confirm your card before you can use it with PayPal. If you don't see this link, you can begin using your card right away.
