Economist - Data with a human touch:
"First in line is Matsushita, a Japanese industrial giant. Last September it launched a 'Touch Communication System' under the slogan 'Data transfer via fingertips'. It allows users to pick up information from a device simply by touching it. The information is then stored in a compact gadget worn on a wristband, and is transferred when the user touches another device. Very weak currents are used to transmit data across the skin's surface, and the data-transfer rate, a mere 3.7 kilobits per second, is much slower than a dial-up modem."
