Nymi Heartbeat Wristband

While we're still a long way off from the complete interconnectivity of the things that make our everyday tasks easier, the Nymi Heartbeat Wristband ($80) could get us a lot closer. At the core of this wearable device is a heartbeat sensor that determines the unique rhythm of your pulse, using it as a form of authentication. It can then, in theory, be used to interact and gain access to a range of devices around you: your car, your home, your lights, your smartphone, your laptop, even the payment terminal at your local coffee shop. In addition to the heartbeat sensor, it also includes motion and proximity sensors, giving you the ability to actually interact with these devices through gesture-based input. While there's still work to be done on making it compatible with everything, the future looks pretty promising (available early 2014).
