But all of these methods for proving identity are only good for a moment. You have to repeat this multiple times across every application you're connected to every day. The lack of persistence is what makes them annoying, and we see real-world potential to create seamless trust with everything around us.

Nymi (formerly Bionym) brings a new authentication model that continuously connects us to all of the things we use—in the form of a wristband. You place your finger on the Nymi Band's sensor, and it measures the wavelength of your heart rate (electrocardiogram, ECG or EKG) to verify your identity. You only have to do this once until the next time you put your Nymi Band back on.
