The ritual of exchanging business cards may soon become a thing of the past, as Japan is developing a method that allows data transmission through a simple handshake.
Thanks to a device the size of a matchbox, weighing about 50 grams, your information (name, title, address, contact number, email) can be sent directly to the recipient’s mobile phone or PDA, and vice versa, simply through physical contact.
Called “RedTacton,” this technology is being developed in the Integrated Micro System Laboratory at NTT. By using optical electromagnetic sensors, the aforementioned “matchbox” will search for similar electromagnetic fields emitted from another person’s body. When the two parties make contact (for example, through a handshake), the data will be transmitted through the body, of course, with an extremely low electrical current, to a device such as a mobile phone or PDA.
The transmitted information will also include a timestamp, just like an email, making it easy for users to remember whose business card this data corresponds to. Managing contact lists will also become more convenient.
NTT hopes to bring this technology to market within the next 2 to 3 years, with a wide range of applications. For example, it could be embedded in medicine bottles and send a message to your mobile phone warning “Do not take” if you mistakenly reach for the wrong medication. There are many types of medications that should not be taken together, yet consumers are often unaware of this. A device like this could serve as an ideal health consultant.
Additionally, RedTacton could be beneficial for forgetful individuals. You could unlock doors simply by touching the doorknob, which is fantastic for those who frequently misplace their keys.
