Apple 13 is a very smart mobile phone, which can not only take photos, listen to music, make phone calls and other basic functions, but also add access cards. Let's see how Apple 13 adds access cards.

Step 1: Open the keychain application.

First, we need to open the keychain application. On Apple 13 mobile phone, you can find the keychain application in the home screen or settings, and click to enter.

Step 2: Add an access card

In the Keychain application, we need to click the+button in the upper right corner, and then select the access card option. Next, we need to input information about the access card, such as the name and card number of the access card. When you have finished typing, click the Next button.

Step 3: Verify the access card

In the process of verifying the access card, we need to put the mobile phone near the access card reader. If the access card reader supports NFC function, we can directly put the mobile phone near the access card reader, and then follow the prompts to enter the password of the access card. If the access card reader does not support NFC function, we need to follow the prompts to put the mobile phone near the access card reader and enter the password of the access card.

At this point, we have successfully added the access card. Next time, you can use your mobile phone instead of the access card to enter the designated area.
