I can tell by you screen name that no matter what I say it won't matter. You "just shut up and take it' sound like a perfect NWO slave.
I can fake a thumb print (or any other finger print temporarily) so easily it ain't funny. There's an old saying; 'locks were made to keep honest people honest, but a thief will always find away around it'.
Do you honestly believe thumbprints will stop the theft of rental cars? If you do than your living in a fantasy world.
It appears you pay little attention to my words so I won't bother anymore other than to say that companies have a right to attempt to protect their property be it thumbprints, retinal scams, DNA, breathanalyzers or whatnot. That is their right just as it is your right to scream about "Big Brother" or "Tyranny" or "Communism" or whatnot.
As to your ability to fake fingerprints. Yeah, suuure you can.
