A new wristband uses the pulse as the password

In keeping with the latest trend in wearable devices, here comes a new hi-tech wristband, which records the wearer’s pulse as a password. The band is a security device that authenticates you based on its reading of your pulse.

A start-up company, Bionym, has developed the Nymi wristband. It uses dual electrodes, which are integrated into its clasp to sense the wearers’ pulse when they touch the clasp even for a few seconds. The device has an accelerometer and a gyroscope, and fitness apps are in development too.

The sensors of Nymi can also be used for gesture recognition, so one can possibly incorporate movement and triggers into the authentication process, other than just the pulse reading of the original wearer.
