Human area network (HAN) technology
A new product by NTT, called “Firmo,” allows users to communicate with electronic devices by touching them. A card-sized transmitter carried in the user’s pocket transmits data across the surface of the human body. When the user touches a device, the electric field is converted back into a data signal that can be read by the device.
For now, a set of 5 card-sized transmitters and 1 receiver goes for around 800,000 yen ($8,000), but NTT expects the price to come down when they begin mass production.
