In case you are not aware, Synaptics is a company that's famous for making fingerprint scanners, especially for Samsung. They have unveiled quite an innovative piece of fingerprint sensing tech today, dubbed the Natural ID FS9100 optical fingerprint sensor. It resembles the "under the glass" fingerprint scanner which we have been hearing about so far only in rumors and given the history shared by Samsung and Synaptics of working together, we are pretty much sure that this is what we are going to see on the Galaxy S8 next year.
"Synaptics' FS9100 family of fingerprint sensors represent a new breed of optical fingerprint sensor technology that is designed to meet the needs of mobile devices, including the ability to image through thick 2.5D glass. In addition to opening the door to new industrial design options, it enables OEMs to provide highly durable, button-free cover glass and more easily provide water-resistant products, while eliminating low-yield glass processing" - Anthony Gioelli, Vice-President of Biometrics Marketing, Synaptics
This new optical fingerprint sensor works flawlessly even when placed under 1mm of 2.5D glass. Additionally, it can also detect prints from wet fingers, which makes it a great companion for water-resistant smartphones (like the Galaxy S8). Since it's meant to be placed below the front glass of the smartphone, the FS9100 is immune to scratches and electro-static discharges by default. This is the perfect addition to the S8, now that Samsung has probably decided to remove the physical Home button and go with a bezel-less display.
