The Nymi wristband eliminates the need for passwords by relying on the users’s heartbeat for identity confirmation.
Researchers have known for decades that each individual’s heartbeat forms a unique pattern of peaks and valleys, which allows the person to be identified. To use the Nymi, users first register their ECG signature by touching a sensor on the top of the band for about two minutes, which allows the device to store and remember their unique biometric pattern. Locked devices can be accessed by touching the Nymi with one hand for several seconds while a second sensor on the device makes contact with the wrist. If the authentication is approved, the signal is sent via Bluetooth to an app installed on the devices. The devices will automatically lock when the wristband is removed.
