How to use Apple Homekit features?

"Apple Home Key is a virtual door card feature based on Apple's Near Field Communication (NFC) technology. It supports two unlocking methods: standard mode and express mode.

- In standard mode, users need to open the Apple Wallet app, select the corresponding door card, and then hold their iPhone or Apple Watch near the lock's NFC recognition area to complete verification and unlock.

- In express mode, the HomeKit smart home platform will proactively prompt users to add the door card to Express Mode settings. After completing Face ID or passcode verification, users can enable express mode. Once activated, users simply need to wake their iPhone or Apple Watch and hold it near the lock's NFC recognition area to verify and unlock."
