Wi-R, a technology developed by startup Ixana, is based on quasi-static electro fields (or EQS). In detail, this means that a simple handshake is enough to transmit information between two individuals, the body then acts as an antenna.
Wi-R works wirelessly at a distance of 10cm (and 2 to 5 meters with a driver), but of course simple contact data transfer remains the most spectacular aspect of this technology.
