International. RedTacton technology, which uses the human body as a secure, high-speed network for data transmission, is a card that sends micro electrical currents with information through the individual. This technology could be implemented in the security industry; for example, using it on cards to limit access to certain spaces or open cars. For those who carry the card, it will only be enough to knock on the doors for them to open.The communication exchange process of RedTacton technology has several phases: first, the RedTacton transmitter induces a slight electric field on the surface of the body; secondly, the RedTacton receiver records the changes in the electric field of the body surface caused by the transmitter. RedTacton is based on the fact that the properties of an electro-optical crystal can vary depending on the changes of a slight electric field.
According to engineer Mitsuru Shinagawa of NTT Microsystem Integration Laboratories, everyday touch can become communication, and even give way to a new concept of telecommunications through physical contact.
