It was just a matter of time: LG today showed off its latest fingerprint scanner technology that allows the biometric scanner to be almost completely hidden in the screen of the device.

Previous ‘button type’ scanners require you to make contact on a raised square or circular button for your fingerprint to be read exactly, so the sensor was usually mounted on the front, rear or side buttons of a smartphone. This has been the standard since Apple’s TouchID launch on the iPhone 5S.

How does the new technology work? LG Innotek, LG’s high-tech research department, cut a shallow furrow of 0.01inches (0.3mm) thick on the lower backside of the cover glass and installed the fingerprint sensor inside of it with supreme precision.

This results in a seamless scanner which gives the illusion of the glass itself reading your fingerprint. Sounds like the next big improvement for smartphones is here, and here to stay.

But when could we expect to see it being used? Not much was mentioned as to when we might see it be applied on a product, but chances are high that it will be used on the distant LG G6 or LG G7.

Do you think this is a big step in biometric technology or is it just another gimmick?
