A week ago, Apple debuted iPhone X and Face ID, a new biometric security mechanism that replaces Touch ID.
Face ID allows users to unlock their iPhone with their face. The same mechanism can also be used to make purchases in various Apple digital media stores, and to authenticate payments via Apple Pay.
The mechanism works by projecting over 30,000 infrared dots onto a face and creating a 3D mesh of it, then comparing it to the stored facial recognition information.
