This biometric system works through a front-facing camera on your iPhone X. It's consisted of a series of incredibly small components, where the crucial one is a Dot Projector. As you can see from the visualization below, the Drop Projector fires up 30,000 invisible dots on your face and creates a unique 3D map. This is why it's almost impossible for someone else to unlock your phone. In addition, this is why your iPhone X can't be unlocked with a picture of you, which is the case with some Android phones.
