The Face ID technology

Face ID Technology

Apple’s Face ID is a facial-recognition technology that launched on the IPhone X in 2017 designed and developed by Apple Inc.
The technology that enables Face ID is some of the most advanced hardware and software that we’ve ever created.

How Face ID Works?

Each time you glance at your phone, the TrueDepth camera system will detect your face with a flood illuminator, even in the dark.
An infrared camera will then take an image, and a dot projector will project out over 30,000 invisible infrared dots to create a depth map of your face and also captures an infrared image of your face.

Your iPhone X (or newer) will check scans (or mathematical models) of your face against the one you've setup and stored on your device to see if it's a match, and if it is, it will unlock your phone or authorize a payment on Apple Play.

Is Face ID safe?

According to Apple, Face ID will recognize you even if you grow a beard, wear glasses or a hat after Face ID is set up. Compare that to Touch ID, which often refuses to work if your finger is wet (rain or workout) or has a cut on it. If there is a more significant change in your appearance, Face ID confirms your identity by using your pass-code before it updates your face data.This makes Face ID much more accurate and reliable in specific scenarios.
