Face scanner (Windows Hello/FaceID)

— a specialized scanner for facial recognition. Note that this is not just about “recognition from a photograph”, but about a full-fledged three-dimensional scanning using a special IR sensor. This allows to achieve very accurate and reliable recognition. And thanks to advanced algorithms, accuracy is maintained even when facial hair changes, putting on and taking off glasses, and other such changes. As for the purpose, the face scanner is mainly used for user authentication — in the case of Windows it is Windows Hello, and for iOS devices it is FaceID.
