I've been prompted to provide the last four digits of my card when using Apple Pay. What numbers should I provide?

Apple Pay does not transmit your card number when making transactions. Instead, a unique Device Account Number is transmitted for added security! If you are prompted to provide the last  four digits of your card, you should provide the last four digits of your Device Account Number instead. This number  is found by going to Settings > Passbook & Apple Pay and selecting the card that’s in use.
