We all want to be more secure, especially now that we know government authorities can basically find our underwear size if we’ve shopped online. And Nymi can actually help with that, using a distinctive feature nobody can copy; your heart. No, not in a cuddly way. In a hard password kind of way.

Your Cardiac Fingerprint

It works like this; everybody’s heartbeat is a little different, and no two are the same. The result is that you have a “cardiac fingerprint” of sorts, a distinctive way your heart beats, to identify you. It’s a type of biometrics that’s often discussed but rarely used due to the difficulty of finding that heartbeat. That’s where Nymi comes in. You simply key the bracelet to your heartbeat, and now, everything you want opened will need to match your cardiac fingerprint.

Security And Redundancy

There’s a bit more to it than that, though. Refreshingly, Nymi uses a three-factor system. The first factor is, of course, your heartbeat. The second is the bracelet itself, and the third is an Authorized Authentication Device, essentially your smartphone or similar tool enabled with an app to serve in that capacity. True, a dedicated thief can probably get at whatever you’ve secured with your Nymi in the first place, but this makes it much harder for crimes of opportunity to happen.

Passwords And Locks


Right now, the Nymi largely exists to get past password screens in the digital world; you key various passwords and the like to your heartbeat, and then use the app to get through. But in the future, it could be used for any number of purposes: Biometrics are viewed as the next frontier in technology, making things easier and smoother to use, and being tied to everything from transportation systems to your credit card. But for now, you’ve got the Nymi to experiment with: It starts at $79.
