The possibility of Apple embedding the Home button into the display of a future iPhone model got a step closer today as a third-party company announced technology that allows fingerprints to be read through Gorilla Glass.

TNW reports that Sonavation has developed ultrasonic fingerprint sensors capable of 3D scanning from beneath the Gorilla Glass Apple uses for its iPhone displays.

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.

There’s nothing to suggest any link between Apple and Sonavation – this is merely an indication that the type of technology required to replace a physical Home button with an embedded one is already out there. A sketchy report last month suggested that Apple is working on this type of technology.

Don’t look for this in the iPhone 6S, though. While a recent leak confirmed our report that the new iPhone would get Force Touch, it also revealed that the external appearance of the phone will be almost identical to the iPhone 6.
