Open up your heart

Trying to remember the multiple passwords that one needs for every device, website and service is an almost impossible task. But one could soon use something rather more personal to prove his identity: his own heartbeat. A wristband called Nymi, developed by Toronto-based company Bionym, confirms the wearer's identity through electrocardiogram (ECG) sensors that monitor the heartbeat, and then communicate that authentication to his devices ranging from iPads to cars. Wearing the Nymi wristband, a user registers their identity by touching a sensor embedded in the top of the band with the opposite hand for about 2 minutes while the Nymi captures an ECG signature. Once stored, it will recognize only this unique biometric template.
