Biometrics are big news this year, whether they’re built into our smartphones, or part of cutting edge new wearable tech. The Nymi falls into the latter category, and it’s a wrist band which will replace your usually less-than-secure passwords with something far harder to replicate or crack: Your heart beat. More specifically, it uses your cardio rhythm, or ECG, pattern – which is unique to you – to verify your identity.
It works like this. The Nymi must be linked with your smartphone using Bluetooth LE (low Energy) at the beginning of each day, a process which is only performed once, and because the clasp closes an electrical circuit, it stops working and forgets everything when it’s removed. By touching a finger on the top-mounted receptor, it’ll record your heart beat.
The wrist band, your heart beat, and the device to which its connected all work together to confirm your identity, without the need for a password. If one part changes, the chain is broken. The Nymi doesn’t store information online either, it’s all based on a direct link between the three elements.
According to Bionym, the company producing the Nymi, the wrist band isn’t only about replacing your awkward passwords. Its built-in proximity sensor and gesture control system means it could be used for unlocking your car or house door, or completing payments with a linked credit card. A software development kit means developers have the opportunity to build Nymi into their own creations too. Click here to watch a video of how it works.
