    So I've been reading a lot about the number associated with your card that is not the same as the actual number. If you wanted to change this number, is it possible? Would removing and readding the card change the numbers automatically or will it always be the same? Just to avoid in case someone decides to maliciously screenshot your phone and you wanted to be safe and change the numbers on the "virtual" card.

    I believe it generates a new unique one time use number with every transaction.

    That's irrelevant. It only shows the last four numbers of the "virtual card." The whole number is never shown therefore a screenshot would be useless to anyone trying to get the information.

    Seems like you're just trying to find flaws in Apple Pay that don't exist.

    There's no way you can just take a screen shot. The original card number is never shown. What's used for payments is the Device Account Number (which is unique to your device, not the card, and stored in the Secure Element) and a one-time, randomly generated dynamic security code. The full Device Account Number is also never displayed.
