South Korean electronics company LG showed its G8 ThinQ smartphone which uses its owner’s veins in the palm for unlocking the screen. “The phone’s ‘Hand ID’ technology identifies owners by recognising the shape, thickness and other individual characteristics of the veins in the palms of their hands,” said LG. The phone also supports depth-sensing face unlocking.
LG says the phoneâs Hand ID tech is the first to use âadvanced palm vein authenticationâ â which could well be accurate.   LGâs Hand ID identifies owners by recognizing the shape, thickness and other individual characteristics of the veins in the palms of their hands. It turns out, like faces and fingerprints, everyoneâs got a unique set of hand veins, so once registered, you can just however your hot blue blood tubes over the handset to quickly unlock in a few seconds. The phone  also put the tech to use for a set of Air Motion gestures, which allow for hands-free interaction with various apps like the camera (selfies) and music (volume control).
