FaceID is a facial recognition technology introduced by Apple, which scans and analyzes the user's facial features through the front camera and infrared sensor, thus realizing the functions of device unlocking and payment verification. FaceID was first introduced by Apple on iPhone, and has been applied to iPhone, iPad and Mac.
How does FaceID work?
The working principle of FaceID is based on deep learning and artificial intelligence technology. It scans and analyzes the user's face through the original deep camera system, including facial contour, eyes, nose, mouth and other features. At the same time, FaceID can also recognize the user's expression and posture, thus avoiding being cheated. The process of identifying FaceID is real-time and can be completed in less than one second.
What are the advantages and disadvantages of FaceID?

B. Good convenience: users can complete unlocking, payment and other operations just by pointing their faces at the screen, without entering passwords or fingerprints;
C. Wide applicability: FaceID can be applied to iPhone, iPad, Mac and other devices, which is convenient for users to switch between different devices.
Disadvantages:
A. Strong environmental dependence: the recognition effect of FaceID is affected by environmental light, angle and other factors, and the recognition may fail;
B. Privacy risk: FaceID needs to access the user's facial information, which may lead to privacy risk;
C. Limited applicability: FaceID can only be applied to devices that support the original deep camera system, and is currently limited to Apple products.
