We know that biometric security, which involves scanning fingerprints or retinas, is quite common in banks and the like, but what if you could simply unlock your front door with your face? It's not like someone can easily duplicate that.
When we read about this, we thought that this was a concept, but no, it's actually something that you can buy right now. All over the world, people are using magnetic and RFID cards all over the place in order to get into their workplaces. There are a few different option available for homes, but they are costly. The FaceID system wills tore up to 500 unique faces in its database and will unlock the front door to anyone in there. A pair of digital cameras allow the system to recreate a 3D image of your face. It runs this rendering through a face-detection algorithm to match the faces up. Since the images are 3D, it stops anyone from trying to hack this system with a photo. The system can also cope with different lighting conditions, it even works in the dark!
It's supposed to be used as a replacement for card systems and FaceID claims a margin of error of 0.0001%, making it pretty secure. This system doesn't come with an electronic lock. You'll have to get that as well if you want to use this device. FaceID is for sale over at Chinavision for $447.
