Redtacton turns the human body into one big swipe card


Redtacton, which looks remarkably like a big pot of kryptonite is said to allow over 200kbps of data through the human hands or feet.

Telecom giant Nippon Telegraph and Telephone Corp. (NTT) is planning a commercial launch of a system to enter rooms that frees users from the trouble of rummaging in their pockets or handbags for ID cards or keys.

It uses technology to turn the surface of the human body itself into a means of data transmission.

How does it work?

As data travels through the user’s clothing, handbag or shoes, anyone carrying a special card can unlock the door simply by touching the knob or standing on a particular spot without taking the card out.


Walk-through ticket gate, a cabinet that opens only to authorised people and a television control that automatically chooses favourite programs.

The system also improves security. It ensures that only drivers can open their cars by touching the doors if the keys are in their pockets, not people around them.
