oRedTacton is a technology developed by Japanese company NTT, which claims it can send data over the surface of the skin at speeds of up to 10Mbps -- equivalent to a fast broadband data connection.oRedTacton takes a different technical approach. Instead of relying on electromagnetic waves or light waves to carry data, RedTacton uses weak electric fields on the surface of the body as a transmission medium.oThe name chosen for this technology is derived from “tacton” meaning “action triggered by touching” combined with red, which in Japanese culture is an auspicious color with connotations of warmth and love, to convey the cordiality and warmth of interpersonal communications.

The transmitting and receiving electrodes of the RedTacton transceiver are completely covered with insulating film, so the body of the person acting as the transmission medium is completely insulated. This makes it impossible for current to flow into a person’s body from the transceiver.When communication occurs , displacement current is generated by the electrons in the body because the body is subjected to minute electrical fields. However, such displacement currents are very common everyday occurrences to which we are all subjected.RedTacton conforms to the “Radio Frequency-Exposure protection Standard (RCR STD-38)” issued by the Association of Radio Industries and Businesses (ARIB)

Broadband and interactive•Duplex, interactive communication is possible at a maximum speed of 10Mbps. Because the transmission path is on the surface of the body, transmission speed does not deteriorate in congested areas where many people are communicating at the same time.• Maximum communication speed may be slower than 10Mbps depending on the usage environment.

Practical Application

Firmo Firmo Kit is used as an alternative to short-range

wireless security card entrance/exit systems. NTT claims Firmo provides a higher degree of security than other technologies.

Why RedTacton

• More secure than Bluetooth.

• Superior than infrared technology.

• Superior than Wi-Fi.

It has no compelling applications that aren’t already available.

Too costly.
