What are the disadvantages of face recognition locks?

There is nothing to say about the recognition rate. The rejection rate is less than 1%, and the false recognition rate is 0.00 1%. This data has been tested by 800 thousand people, not nonsense. The recognition speed is less than 1 sec. Soon! Attendance is more intuitive, you can look at your face directly, non-contact, healthy and environmentally friendly. Hehe, the other thing is a dual camera, so the recognition rate is more accurate. The buttons on the panel are still being touched. It's just more expensive than fingerprints, and it's still very easy to use.
