Benefits of paying by brushing face: Compared with other verification methods, face recognition is obviously more convenient. Because users may not remember some of their personal information, such as password, ID number and bank card information, or they may not receive verification information such as check code for various reasons. Face recognition doesn't require users to remember any information, and they don't need to carry anything extra. They just need to brush their faces at the camera of the mobile phone.
Disadvantages: There are certain risks. 1, reproducibility. Replication is the most commonly used means to crack passwords, and it is also quite common to steal digital passwords and take fingerprints to decrypt them. Similarly, the five senses are easier to copy. People are exposed every day. By taking pictures, you can get a person's facial features and copy them. 2. unstable. Unlike digital passwords or fingerprint verification, people's five senses are unstable.
