"The dealership claimed that the fingerprinting was for my protection. To make sure I'm really who I say I am, and haven't just stolen someone's social security number.
But I don't get it. How does that work? No one's checking to make sure the fingerprint I leave matches the one on file with the DMV. There's no forensics expert on staff. And I don't have data on this but I feel pretty certain that any car thief worth his salt probably already has more than one set of prints on file.
Dollar Rent-A-Car tried fingerprinting their customers for a while. They gave up after realizing that it had no effect on fraud or theft. Simply, treating your customers like felons is bad for business.
