According to the Interim Measures for Inquiring about Real Estate Registration Data issued on October 26th, 20 18/KLOC-0, if the owner doesn't have a mobile phone, he usually needs to go to the window of the real estate registration agency for face-to-face signing, and the staff of the real estate window will ask about the important matters confirmed this time in person, and then sign in writing.

If the owner has a mobile phone, he can also sign in at the real estate registration agency, and some people choose to confirm the registration online or on his behalf. At this point, the parties can sign their fingers on the computer client or mobile phone as long as they recognize the face through the camera.
