Bionym has launched the world's first wearable authentication device that uses a person's unique heartbeat to authenticate their identity.
The device is called the Nymi and the Canadian firm believes it provides better security and negates the need for a password.
Worn as a bracelet, it has an embedded sensor that recognises the wearer's unique electrocardiogram and then communicates it to their devices using Bluetooth, unlocking whatever application they are attempting to open.
The technology can be used in simple computing or for other more complex things such as cars.
It offers a three-factor security system and requires a personalised bracelet, a smartphone registered to the Nymi app and the owner's unique heartbeat.
Wearable technology is now starting to enter the market and users of the Nymi can also connect to e-mails, text messages and social media.
Karl Martin, chief executive officer of Bionym, said: "When it comes to identity, privacy is a chief concern. The Nymi has been built by the principles of privacy by design. This means that each user has complete control over their data and identity."
