Finger vein scanner will unlock your door
We're not really sure why a good ol' fingerprint reader wouldn't do the trick (oh, wait), but apparently Sumitomo and Hitachi decided what the world really needs is a finger vein reader to lock and unlock doors. While this exact technology is certainly not brand new, this particular implementation seems to be. From what we can tell, you place your fingertips on the reader, and presto, the door unlocks, assuming your veins match its stored list of 10 authorized patterns. According to Plastic Bamboo, it'll cost ¥150,000 ($1,280) -- but, at that price, we'll stick to the tried-and-true analog deadbolt method.
