Body field communication

Can you imagine locking or unlocking a door simply by touching the doorknob? Or being able print a document by placing one hand on the copy machine and the other on your laptop? It may sound like science fiction but is actually a very real possibility thanks to a new close-range communication technology called RedTacton. First developed by Japanese NTT (Nippon Telephone & Telegraph) in 2005, the new technology takes wireless communication a step further by replacing the radio waves used for transmission over Bluetooth, IR and similar technologies with the minute electrical field emitted by the human body.
