John McLear, a web developer and founder of an education IT company in Bradford, developed the NFC Ring for his own use in 2012. Then a friend said he'd pay for one, so McLear put the project on Kickstarter, asking for £30,000 -- but eventually raising £241,947. He says his ten-strong company will have shipped 25,000 rings by February.
Two NFC tags line the ring: one, on the outside, lets you publicly share information such as pictures, links and contacts; the tag inlaid inside is for private data, such as the unlock code for your home (you'll need digital locks), phone and, in McLear's case, his Peugeot 205 -- all managed by an Android app. As a security test, McLear hired a local pickpocket to try and steal the ring. "He showed it was much more difficult to get a ring off someone's finger than steal their wallet or keys," he says. "The current method of securing a house with a normal key is so broken."
A Wi-Fi NFC Ring is in the works, but McLear is most excited about a medical application planned for 2016: "There will be a bright light on the inside of the loop that 'samples' your blood," he says. "You take a picture of your blood cells and count the platelets."
