Biometrics components maker Synaptics recently developed a new fingerprint sensor for Android OS smartphones. In their latest statement, Synaptics said that the new fingerprint sensor will come with a host of soft-button features, and they can be mass produced by Q3 2017.

The FS4600 will be able to support differently shaped phone sensors – their statement specified “square, round, pill shape, and slim rectangular buttons for the front, back or side of devices”. Phone brands will be able to choose their preferred coating (polymers, ceramics, or glass).

Besides fingerprint sensing, the FS4600 range will also include support for two 0D soft buttons (for Android navigation keys), force sensing (pressure-sensitive touch), and swipe navigation. There’s also a proprietary security system consisting of anti-spoof technology and 256-bit AES with TLS 1.2 encryption.

Ars Technica likened the new pressure-sensitive sensor to Apple’s current ForceTouch feature found on iPhone displays. There’s a chance that a different type of press can render a different outcome or function; a soft press could be for unlocking the device, while a harder press can bring a user to a specific app, etc. The inclusion of swipe support on the sensor could also make swipe gestures more widespread across Android smartphones as well.
