The Surface family includes Surface Pro, Surface Laptop, and other Surface products. Surface is designed to help organizations, students, and consumers be more productive.
I'm also having the exact same issue. The Device Manager says the fingerprint scanner is present and no issues. When you go into the Accounts > Sign In Options and try to add another fingerprint, the scanner simply doesn't scan. No errors or anything. It's as if it doesn't work even though it says its there.
Extremely Frustrating to say the least.
