Life by heartbeat

A bracelet that acts as a fingerprint for your devices.

Soon, if a pack of researchers at the University of Toronto have anything to say about it, credit cards will finally be obsolete. There’s a couple alternatives out there already, like the iPhone’s Touch ID to purchase songs from iTunes, but this new invention called Nymi (by Bionym, an off-shoot of the school) allows payment by way of a simple wave of the arm. The slick bracelet, currently available on pre-order (for only $79, chump-change considering its possibilities), identifies a person’s identity by their heart beat, and can also be used to open cars, check into flights and open hotel room doors. Just when we thought phone watches were out-of-this-world, welcome to the Internet of Things in hyperdrive.
