LG Made A Fingerprint Sensor That Can Read Your Finger Through Glass


No more unsightly fingerprint sensors

The next standard tech that’s popping up in mid-range smartphones and flagship devices is the fingerprint sensor. The problem is that there’s no real optimal place to put it – if it’s on the front, it takes up valuable bezel space. If it’s on the back, you can’t use it when the phone is lying down flat on a table. When it’s on the side, it’s tiny and hard to use.

LG may have found the best solution as far as reading your digits are concerned – the company has managed to create a fingerprint sensor that resides just below the glass of a mobile phone, which allows it to read your fingerprint through the glass. Despite its relative stealthiness, the sensor is more effective than a physical button, with a failure rate of just .002 percent on average.

While LG hasn’t officially announced when this stealthy new fingerprint sensor will be making its debut, you can bet that the Korean company will be using it for their own phones first before offering it to their competitors.
