Futuristic bracelet uses heartbeats as a password - 

A security startup has unveiled a wearable device that's designed to replace the hassle of passwords by using a person's unique heartbeat signature to log on to computers and unlock car doors. While the device is intriguing, the dearth of key technical details makes it impossible to assess the marketers' promise that it provides "complete security without compromising convenience."

The Nymi is a small bracelet equipped with a sensor that reads the electrocardiogram (ECG) of the person wearing it. Once it has verified that the heart signature belongs to the person who registered it, it provides a means of authentication that can in theory be used to access a virtually endless supply of electronic devices, including airport kiosks, hotel room doors, and sensitive computer networks. It relies on three factors of authentication—that is, two things the user has in the form of the bracelet and a paired mobile device, and one thing the user has in the form of a verified ECG.
