As we all know fingerprint readers have always required the addition of a dedicated button in a device, phone manufacturers usually include them on the home button, or sometimes at the back of a device. That has been the case until now.
LG today announced a new fingerprint sensor module that sits beneath glass. This means there wouldn’t be any exterior sign whatsoever of a finger print button. Think of it this way, your device exactly the way it is, but without any sign of a fingerprint button which is hidden under the glass.
This has lots of benefits, apart from the fact that the fingerprint sensor wouldn’t be easily scratched since it sits under the same tough cover glass as the display (most devices feature Corning Gorilla glass), waterproofing a smartphone becomes easier when there is no discrete button for the fingerprint reader.
Apart from the benefits listed, LG claims that its new fingerprint reader is also very accurate. According to the company, the new fingerprint sensor module has a false acceptance rate of 0.002 percent although the speed of recognition through the glass might not be the same, that will be determined by several products.
A spokesperson for LG Innotek told The Korean Times,
We are in talks with some handset manufacturers to commercialize the new modules within the year.
