Instead of inserting a card or scanning a smartphone to make a payment, what if you could simply touch the machine with your finger?<\/p>\n

A prototype developed by Purdue University engineers would essentially let your body act as the link between your card or smartphone and the reader or scanner, making it possible for you to transmit information just by touching a surface.<\/p>\n

The prototype doesn’t transfer money yet, but it’s the first technology<\/a> that can send any information through the direct touch of a fingertip. While wearing the prototype as a watch, a user’s body can be used to send information such as a photo or password when touching a sensor on a laptop, the researchers show in a new study.<\/p>\n

“We’re used to unlocking devices using our fingerprints, but this technology wouldn’t rely on biometrics\u2014it would rely on digital signals. Imagine logging into an app<\/a> on someone else’s phone just by touch,” said Shreyas Sen, a Purdue associate professor of electrical and computer engineering.<\/p>\n

“Whatever you touch would become more powerful because digital information is going through it.”<\/p>\n

The study is published in Transactions on Computer-Human Interaction<\/i>, a journal by the Association for Computing Machinery. Shovan Maity, a Purdue alum, led the study as a Ph.D. student in Sen’s lab. The researchers also will present their findings at the Association for Computing Machinery’s Computer Human Interaction (ACM CHI) conference in May. <\/p>\n

The technology works by establishing an “internet” within the body that smartphones, smartwatches, pacemakers, insulin pumps and other wearable or implantable devices can use to send information. These devices typically communicate using Bluetooth signals that tend to radiate out from the body. A hacker could intercept those signals from 30 feet away, Sen said.<\/p>\n

Sen’s technology instead keeps signals confined within the body by coupling them in a so-called “Electro-Quasistatic range” that is much lower on the electromagnetic spectrum than typical Bluetooth communication. This mechanism is what enables information transfer by only touching a surface.

Even if your finger hovered just one centimeter above a surface, information wouldn’t transfer through this technology without a direct touch. This would prevent a hacker from stealing private information such as credit card credentials by intercepting the signals.<\/p>\n
