Apple is rolling out facial recognition to unlock its new iPhone X, as has been rumored for months and confirmed in leaks over the weekend. The technology builds on Touch ID and is called Face ID, of course. It uses a new selfie camera setup in the iPhone 10 called the “TrueDepth camera system.” TrueDepth uses a set of sensors, cameras, and a dot projector to create an incredibly detailed 3D map of your face.
