Tapping into a new security trend

The system uses vibrations to identify the finger, rather than the code it is tapping or pattern it is swiping.

Engineers at Rutgers University may have put their finger on a very secure but inexpensive way of allowing people to access everything from their homes to their cars without the need for a key or for complex biometric measures. 

Fingerprint sensors, voice recognition, iris scans and facial recognition may all be very secure ways of consumers being able to convince their digital devices that they are who they say they are, but until the technology behind such systems becomes affordable and widespread, they won't be moving beyond flagship smartphones or banking services any time soon.
