I use a Dell Inspiron which has this feature. It works very well under 
Windows (and I have used some in the past which were very hit-and-miss.) 
The fingerprint device doubles as a regular clicky power button.

Most of the time this machine runs Linux (LMDE Debbie). I have looked 
into enabling the fingerprint feature there but gave up on learning how 
patchy the support for these devices is.

To cut to the chase, in my experience this gizmo won't work under Linux 
unless you vault through flaming hoops to make it do so. I strongly 
suspect that you won't know the capability is there and therefore you 
can safely ignore it.
