How does Apple's mobile phone copy nfc function of access card?

The NFC function of copying access cards by mobile phones usually depends on the "key" function in the "wallet" application. The steps are as follows:

1. Ensure compatibility: Make sure that your iPhone model supports NFC function and is running an iOS version that supports copying access cards. Generally speaking, iPhoneXR and later models, as well as iPhone, support NFC access card copying. Make sure that your access control system supports NFC access card copying, and the hotel or access card issuer allows the use of digital access cards.

2. Add access card to wallet: Open the Wallet application. Click the plus button in the upper right corner. Select the Scan or Add Card option. In the pop-up list, if there are "access card" or "key" options, select them directly. If not, you may need to scroll to the bottom of the list and select "Other Cards", and then look for options related to access control. If your access card supports direct addition, please follow the on-screen prompts to place the physical access card near the NFC sensing area of iPhone, and iPhone will try to read and copy the card information.
