Wearable tech trend meets heartbeat authentication to store passwords and open doors

Even casual readers of WikiTrends know that wearable technology is the Next Big Thing. Regular readers know that biometric identification is also coming down the pike, what with the iPhone's fingerprint unlock now becoming mainstream. Currently, we are seeing lots of gadgets that are taking advantage of both these trends, meaning that we can expect to be flooded with examples of wearable tech and bioID in the coming months and years. Like a fingerprint, your heartbeat is unique. The Nymi is an electronic wristband that allows you to wirelessly communicate your identity to all of your devices so that they know you are you. It uses your unique cardiac rhythm to authenticate your identity, creating a password and key-free environment. Turn your wrist and the wristband's proximity detection and authentication knows that you want your car unlocked. It can replace everything from the PIN on your credit card to the account information on your gaming console. Here's how it works: Clasp the Nymi around your wrist it powers on. By placing a finger on the topside sensor while your wrist is in contact with the bottom sensor, you complete an electrical circuit. After you feel a vibration and see the LEDs illuminate, your Nymi knows you are you and connects to devices via your mobile device using Bluetooth Low Energy.
