FaceID combines home security systems with facial recognition. It will likely take over from the usual password, swipe card, retina and fingerprint scanning systems that we already use. It isn’t just a concept either.
FaceID is available right now and looks cool enough for any front door. It uses two digital cameras to create a 3D image of your face. Your face model is stored and matched with whoever stands in front of the system so it can decide whether to let you in or not.
