"Facial scan. This sign-in requires special camera hardware with IR capabilities—so it can work in any lighting, including pitch black darkness—and cannot be retrofitted to existing webcams, or to Kinect. (I could see a future Kinect peripheral adding Windows Hello support.) Today, you pretty much need an Intel RealSense camera to sign-in with Windows Hello. This camera is shipping in a variety of PCs, including some from ASUS, Dell, HP and Lenovo. And you can order a developer kit directly from Intel for $100 if you want, though be aware that is has some onerous hardware requirements (such as needing a 4th generation or newer Intel Core processor). I recently did purchase this camera for Windows Hello testing."

Or more simply, this:

"This requires more than just the webcam on your PC or laptop, but a special array with Intel currently providing the hardware with its RealSense set ups.With a RealSense camera, either built in or an external one like the Intel developer kit we have, you'll be able to set up Windows Hello to log you in to your computer without touching a button, verify your identity or even complete purchases in the Store."
