What if the property prompts the owner to go home and scan the code?

It is necessary for the owner to remind him to go home and scan the code. During the epidemic, residents in low-risk areas have to scan the code to register when they go home. The owner only needs to download an owner-specific APP on the mobile phone, register with the mobile phone number registered by the property, and use it for free after registration and verification. You can scan the QR code directly when you enter the door. If there are visitors at home, the host can also send the QR code to the guest's mobile phone, so that the guest can directly scan the QR code to verify and enter.
