Heartbeat sensors are typically used in a medical sense but when you bring it into the tech world, a whole new world of possibilities opens up. Nymi is a password authenticator that uses a heartbeat sensor to unlock your technology for you.
In today's world everything is public, except for one's log-in credentials. Remembering the long list of passwords and usernames one uses for their phones, computers and e-mail accounts can be an annoying process if they differ greatly.
What Nymi by Bionym does is it allows people to sign into these things naturally by sensing one's unique heartbeat. You've heard of unique fingerprints opening things up but this is another step forward. Nymi acts a wristwatch type device that authenticates these things through Bluetooth once it identifies the heartbeat.
