Unlocking smartphones by fingerprint has been possible since the Motorola Atrix 2 back in 2011, with both Samsung and HTC embedding fingerprint sensors into some of their more recent models, but the process could get a whole lot slicker thanks to some new tech.
While current sensors need some space beneath the display, future smartphones could read your fingerprint through the screen. TNW reports that Sonovation has developed ultrasonic fingerprint sensors capable of 3D scanning from beneath the Gorilla Glass used on many high-end smartphones.
Though details on how it will work are sparse, Sonovation says its sensors are “capable of capturing fingerprint data into the ridges and valleys.” It also says 3D scanning can take place if a finger is wet, dirty or oily — all without compromising accuracy.
