Passbook already stores your boarding passes, tickets, coupons and more. Now it can store your credit and debit cards, too. To get started, you can add the credit or debit card from your iTunes account to Passbook by simply entering the card security code.

To add a card on your device, go into Settings, open Passbook & Apple Pay, and select “Add Credit or Debit Card.” Alternatively, on iPhone, you can just open Passbook, then swipe down and tap the + sign. From there, use your iSight camera to enter the card information or type it manually. The card you store in iTunes becomes your default payment card, but you can always switch it in Settings.
