BUFFALO, NEW YORK — Researchers at the University of Buffalo have developed a new biometric tool that scans your heart to unlock your phone or log onto your computer.
Scientists have designed a system that uses a low-level Doppler radar to identify the shape and size of a person's heart, Gadgets Now reported.
The system needs eight seconds to record the shape and person's heartbeat. It then continuously monitors the person's presence.
Researchers claim the system poses no health risks as the radar system uses very little power.
It is a passive, non-contact device, so people don't have to spend time authenticating themselves.
The heart scanner works on individuals up to a distance of 30 meters (98 ft).
The team now says they will work on shrinking down the system so it can be installed onto computer keyboards and smartphones.
