Can the hotel open the door by scanning the code with a mobile phone? Can WeChat scan the QR code to open the door?

The landlord said, book online, go to the designated room, and the guest's mobile phone scans the QR code of the door lock to open the door. I only know that some homestays will do this. Just use your official WeChat account to book a room for a guest, using a QR code lock, which should be used in conjunction with the software. Guests will receive a QR code key after making a successful reservation. At this time, they need to register the key help software or applet and get the QR code key to open the door. Self-service booking has been completed. You can check in and check out. If you want to stay, you can still use the official WeChat account or APP of the store to stay. However, they lock the door and scan the QR code of your mobile phone. I have also seen the QR code on the mobile phone scanning lock. That's the Bluetooth lock of the QR code, and the same QR code is unlocked.

At present, many hotels can open the door by scanning the code with their mobile phones. Many apartments I have lived in, such as Wanda SOHO Apartment, Ibis Hotel and E+ Apartment, all open their doors with QR codes, but guests still have to go in through the front desk after booking online.
