Microsoft’s new Lumia 950 and Lumia 950 XL, which are expected to make their official debuts tomorrow, will feature iris scanners that allow you to unlock your device simply by looking at it, according to new claims.

The Lumia 950 lineup will be Microsoft’s first flagship smartphone offering since the software giant acquired Nokia’s handset business last year. Windows fans have been waiting a long time for the launch to come, and Microsoft is going all-out to ensure it doesn’t disappoint.

The Lumia 950 and 950 XL are expected to offer premium designs with high-end specifications, including 20-megapixel rear-facing cameras with Carl Zeiss optics, Quad HD displays, and 32GB of storage as standard with microSD card slots for expansion.

They will also feature iris scanners, which will allow owners to unlock their device simply by looking at it, according to @Windows10Lover. The image above shows a secondary sensor sat alongside the front-facing camera on a Lumia 950.

Microsoft brought facial recognition to Windows 10 with a feature called Windows Hello. Using Intel RealSense technology, it allows users to login without actually typing in any passwords; they simply have to look into their PC’s camera.

It’s thought similar technology will be baked into Microsoft’s next-generation smartphones, too, giving them an edge over competitors like Apple, Google, Samsung, and others, which have chosen to support fingerprint sensors instead.

Microsoft’s event kicks off at 10 a.m. EDT on Tuesday, and you’ll be able to find full coverage here on TechnoBuffalo. Alongside the Lumia 950 and 950 XL, we expect Microsoft to announce the entry-level Lumia 550, and a new Surface Pro 4.
