Human handshake opens data stream
A system that automatically transfers electronic data when two PDA-carrying humans shake hands has been developed by two Japanese telecommunications firms, according to news reports. Japanese newspaper Nihon Keizai Shimbun reports that Nippon Telegraph and Telephone and its subsidiary NTT DoCoMo have developed the system, which relies on the conductivity of human skin to transfer data between individuals.
Sources at the two companies say that the system allows up to 10 megabits of data to be transferred per second.
David May, an expert in wearable computing at Bristol University in the UK, says the system might provide a valuable new way to transfer large amounts of information. He believes the system might have an advantage over wireless communications by keeping data private.
