When the user uses it for the first time, the unique biometric information of the user is collected through the light sensing dot matrix, and then connected with the user account after real-name authentication, so as to achieve the effect of safe payment. In other words, even if criminals hold our photos or videos, they can't pass the authentication of paying by brushing their faces.

Brush face payment is a new payment method based on artificial intelligence, machine vision, 3D sensing, big data risk control and other technologies. The face recognition ability of computer is far superior to that of superhuman brain. Whether it is hair style change, routine makeup, fat and thin change, or even micro-plastic surgery, the computer can accurately identify the similarity.
