Innovation That Matters

Hack-proof biometric device could replace passwords

JAR is a personal biometric crypto-key, which uses the customer's fingertip as their password for every login and registration.

The sheer number of passwords needed to protect online accounts means that one inevitably gets forgotten every now and then. But a new device called JAR, developed by the German startup of the same name, could put an end to this traumatic process of account retrieval, by replacing passwords altogether.


JAR is a personal biometric crypto-key that uses the customer’s finger tip as their password for every login and registration. Boasting 100 percent security, it would take a hacker 6 quadrillion years to access the user’s data. The device comes in the form of a touch sensitive button, which plugs into smartphones and laptops via the audio jack. It can easily be attached to a keyring and can be replaced if lost without any longterm disruption to users’ accounts. JAR will not store or access any of the data protected by its device and plan to make the software completely open source.


In the past decade the number of stolen personal datasets and the global annual damage resulting from cyber attacks has increased massively. JAR hopes to change this by reducing the possibility of compromised accounts and password leaks. JAR is currently crowdfunding on Kickstarter where backers can pre-order the device for an early bird price of USD 69, for delivery in January 2016. How else could the digital world be made safer using biometric technology?
