The face-brushing menu of mobile banking of China Construction Bank does not exist, and the face-brushing score has not reached the threshold. The face failure at the scene is too different from the photo information of the ID card bound by the bank, and the matching degree is not appropriate. In this case, users can go to the bank to update their identity information, or constantly adjust the shooting angle, environment and light to improve the shooting quality. The score of brushing face did not reach the threshold. In this case, you can directly update the face information through the security center in the = icon above the mobile banking, and then brush your face for authentication. The latest software version pushed by the system has not been updated, which will also lead to the failure of the data transmission terminal for face recognition and authentication, leading to the failure of face recognition. In this case, we only need to update the latest version information of the device in time, and then carry out face recognition authentication again to solve the problem.
