It depends on the fingerprint reader. They don't all make a simple image of your finger to
check the fingerprint. It seems Wikipedia has a nice article about it, so I'll just shup up:

But yeah, you'd want to use it only for local authentication.

It's not an image. But still an authentication token. And it can't really be replaced in case
it leaks.

And unless you always wear gloves, this information can easily leak.
