Like many other handsets currently on the market, Microsoft's rumored Surface Phone, which will use Windows 10 Mobile, is likely to come with a fingerprint sensor. It would be the first Windows phone to include a fingerprint sensor, and according to a patent, the sensor may also be pretty unique.

In Microsoft's 'Fingerprint Detection with Transparent Cover' patent, the company explains how a thin cover on an electronic device would enable fingerprint scanning on thinner products. This kind of sensor may be what's included in the Surface Phone.

It still isn't known if the Surface Phone will be one product or the start of a product family.
