MEMES on Instagram: "🤣 iPhone face recognition, called Face ID, is Apple’s facial recognition system that lets you unlock your phone, make payments, and verify apps just by looking at your screen. It works by using a TrueDepth camera system—a combination of infrared sensors, a dot projector, and a front camera—to scan over 30,000 invisible dots on your face and create a detailed 3D map. This map is stored securely in the phone’s chip (not online) and compared each time you look at the screen."
