RedTacton is a new technology that uses the human body as a wireless transmission path for data. It works by transmitting signals across the body's electric field. Previous intra-body communication methods had limited range and speed, but RedTacton provides high-speed transmission without deteriorating over distance. It could enable applications like touch-based printing, sharing between devices with a handshake, and unlocking doors with a touch. RedTacton provides more secure communication than other short-range wireless as it is difficult for signals to be intercepted.
