编辑“How to Add a Credit Card to Passbook”（章节）

Passbook, also known as Wallet, is a digital wallet application on iPhones that allows users to store and manage digital versions of their credit cards, loyalty cards, boarding passes, and more. Adding a credit card to Passbook is a simple process that can be done in a few easy steps. Here's how:

1. Open the Wallet app on your iPhone.
2. Tap on the "Add Credit or Debit Card" option.
3. If your iPhone has Touch ID or Face ID, it will prompt you to scan your fingerprint or face for authentication. If not, you will need to enter your iPhone passcode.
4. Choose the option to add a new card and position your credit card in the camera frame to capture its information, or manually enter the card details such as the card number, expiration date, and security code.
5. Once you have entered the required information, tap on "Next."
6. You may be prompted to verify your card with your bank by entering a one-time password or receiving a verification call or text.
7. After your card has been verified, tap on "Done."

Your credit card will now be added to your Passbook and ready to use. You can also customize the name of your card, choose a preferred payment method, and set up notifications for transactions. Keep in mind that not all banks and credit card issuers support adding their cards to Passbook, so it's best to check with your bank beforehand.
