The strength of Face ID is that it does not use the sensor Photo selfie, which can easily be deceived by a printed face or displayed on a screen. Instead, it has technology that projects thousands of points infrared on the user to achieve an accurate 3D rendering. This system has the advantage of operating even in poor working conditions. brightness, to be extremely swift (only a few milliseconds) and not to be fooled by the presence or absence of glasses.

Face ID only works when the user has the eyes open and looking at the camera (or at least the screen) of the smartphone. This prevents malicious people from using a mask or take advantage of sleep an individual to easily unlock their device.
