Japanese telecom company NTT is soon to launch a product that transmits data via your body, effectively turning you into a touch-technology swipe card. RedTacton is a card-like gadget that you simply carry anywhere on your person, and it transmits data via electric fields— a world's first according to NTT.So you can open an office door keylessly, unlock and start your car, or any of a million other applications currently using swipe-card entry.
Applications could include a walk-through ticket gate, a cabinet that opens only to authorized people and a television control that automatically chooses favorite programs.
It's clearly more convenient than having to fish out a conventional card, and more secure than a wireless device whose signal could be snooped on. NTT even foresees medical applications in the future, since the system could easily and discretely transmit health-sensor data to doctors and nurses as they touch you during exams.
