Unlocking cars and activating devices securely could soon be a matter of simply touching them, thanks to a communications system that transmits data across the skin. In an August 4 article at NewScientist.com this new technology from German company Ident Technology is described. Here are a few words from the piece:
...the system operates at just 30 nanoamperes, making it entirely safe for people to use. The code transmitted by the electric signal allows cars to be unlocked, doors opened or other devices started... A credit-card-sized system should run for up to three years without a change of battery and could cost only a few dollars to make.
