Если нет встроенной, можно камеру купить с такой функцией.
Я думаю, ты ошибаешься: With Windows Hello, there are two types of biometric recognition through cameras: iris and facial. The facial recognition side of Windows Hello works by bouncing infrared (IR) light off your face and picking it up with a camera. An image of your face is then compared against one that's stored on your PC. If they match, you're logged in. The iris scanning side — famously found in the Lumia 950, 950 XL, and HP Elite x3 — instead takes a picture of your iris and compares it to one stored in your device.
