Hi 👋 that information isn't directly provided to you, but you can determine it. Each card Payment Method will have a fingerprint on it, which is a hashed value unique to your account and the Customer's card number. You can check to see if your Customer ends up with multiple Payment Methods with the same fingerprint value (indicating they added the same card more than once) and can then, if you wish, take action to clean up that duplication for them.
