Xiaomi has unveiled a new smart lock that doesn't just do away with keys, but gives you 10 alternative ways to open your front door - including AI facial recognition. Facial recognition makes a lot of sense in a smart lock, letting children and people with limited mobility unlock the door without the need to enter a passcode, reach a fingerprint sensor, or carry a phone or smartwatch (though these are all alternative options).
The lock projects spots of light (invisible to the naked eye) onto your face to capture details and draw a unique map. Once this is done, you will be able to unlock the door without touching it. 3D live anti-counterfeiting prevents would-be burglars from using a photo to trick the system, and the facial recognition is disabled for 15 seconds after you close the door to avoid accidentally triggering it if you look back.
