Source? Financial services corporations fingerprint both their employees and contractors. I've never seen a distinction in the process for either.
The requirement of fingerprinting does not in and of itself make some an 'employee' or vice versa, but there are precedents in Texas, like this example, that could inch Uber even closer to this line.

Because it's not about finger prints: that's trivial to do. (Hell, you could probably come up with a simple lens to put on a cell phone to extract enough info to get a print... Not to mention existing services. They're lying if they say this puts too much burden and couldn't continue to operate. No, they want to keep the fiction that there are no Uber driver employees, that they're all, to use the brain-dead term working in the "sharing economy".

I'm sure Uber is obviously more informed than me but seems like a tight line they're at. And the IRS can weigh in with their own decision, too.
