As the password makes its slow fade towards extinction, many technologies are jockeying for position as the next method for securing online accounts. We’ve told you about brain wavesfingerprints, even magic rings, but a new technique is literally getting to the heart of the matter.

A wristband dubbed Nymi confirms a user’s identity via electrocardiogram (ECG) sensors that monitor the heartbeat and can authenticate a range of devices, from iPads to cars. Developers at Bionym, the Toronto-based company that makes the device, say the peeks and valleys of an individual’s heartbeat are harder to imitate than the external features of biometric systems, like fingerprints or facial recognition.

To register their identity, uses touch a sensor on top of the wristband for about two minutes while Nymi records an ECG signature. Once it’s stored, it will only recognize that signature.
