So I was randomly looking at images on my computer and I found these in /usr/share/gnome-control-center/pixmaps:

enter image description here

I didn't think Ubuntu had any built in fingerprint reader support. So why are these here and did I miss something? I haven't installed any fingerprint reader related packages that I know of.

Those are there when you need them. You don't need a fingerprint reader for those images being there at all, when you get a fingerprint reader the images don't need to be downloaded and installed.

Those images are provided by the gnome-control-center-data which provides non-architecture dependant files needed for Gnome Control Center to work. The fact that the images are there doesn't mean that you have a fingerprint reader, but that your system will be ready the very moment you install one.

Hmm. Got any sources by any chance? Seems a bit odd to me, especially since there isn't a whole lot of software out there that would ever even use this. – Seth Mar 10 '14 at 4:51
@Seth long description of the package: "This package contains data files (icons, pixmaps, locales files) needed by the configuration applets in the gnome-control-center package." – Braiam Mar 10 '14 at 4:52
Then maybe there's an applet that uses these? Per the answer below, I've done some Googeling and it does appear that the default gnome settings manager does support something to do with fingerprint reading. – Seth Mar 10 '14 at 16:55

GNOME does, in fact, have "built-in" fingerprint reader support.

I mainly use Unity, but when I log in with Gnome I don't still don't see any fingerprint options.. – Seth Mar 10 '14 at 16:39
@Seth I see. Just to be clear, you did enable fingerprint login as the article above mentions? – Chris Mar 10 '14 at 16:41
No I did not, because I can't find anything related to fingerprints in the place it said to look. – Seth Mar 10 '14 at 16:43
Upon using my Google fu, it appears that this was an older gnome feature that has since been removed. – Seth Mar 19 '14 at 4:34
