Sending and receiving data is hassle-free nowadays because of the modern technology we have. People now exchange information for free with the help of digital platforms.  Recently, the researchers have developed a technology which is capable of sending and receiving digital information and this information can be in form of photo, video, text messages or even password protected files. It can be send by touching a particular surface with your finger only.

Sometimes you might have faced problems in making an online payment but researchers and scientist came out with a smart method through which you don’t need any kind of accessories to do transactions. Now to make a payment you don’t need a card or to scan a smartphone as there is now a much accessible way where you just have to simply touch the machine with your finger and the rest of the process is done by the machine itself. This prototype is developed by Purdue University’s engineers and it will allow your body to act like a machine with the help of lots of sensors. Now your body acts as a link between your debit or credit card and smartphone.

What happens after wards is that the reader and scanner make a joint relationship which is detected by networks of digital codes and QR scanners. This prototype is a trial model. Though, money transferring cannot be done with this because of safety issues and the risk of bouncing money. Still, many other types of digital information can be easily transferred just by a touch.

While wearing the prototype device as a watch, a user's body can be used to send information such as a photo or password, the researchers shows in their new study. Shovan Maity, Purdue alum, led the study as a Ph.D. student in Shreyas Sen's lab.

We're used to unlocking devices using our fingerprints, but this technology wouldn't rely on biometrics, it would rely on digital signals. “Imagine logging into an app on someone else's phone just by touch.” said Shreyas Sen, a Purdue associate professor of electrical and computer engineering. Whatever you touch would become more powerful because digital information is going through it. The study is published in ‘Transactions on Computer-Human Interaction’, a journal by the Association for Computing Machinery.
