when the user uses it for the first time, he collects the unique biometric information of the user through the light sensing lattice, and then connects it with the user account after real-name authentication 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.

Face-brushing payment is a new payment method based on artificial intelligence, machine vision, 3D sensing, big data risk control and other technologies. The computer's face recognition ability is far superior to that of the human brain. Whether it is hair style changes, routine makeup, fat and thin changes, or even micro-shaping, looks similar, the computer can accurately identify them.
