What specific hardware component does Apple's Face ID use to project and analyze thousands of invisible dots on a user's face?
Show answer
TrueDepth camera
The TrueDepth system uses an infrared emitter to project over 30,000 dots to create a 3D map of the face, making it much more secure than 2D photo-based recognition. While highly secure, Apple notes there is a higher probability of a false match with identical twins.
