Drivers license. In Texas. They started raw image scanning of fingerprints coupla years ago, but they weren't actually encoding them in real time...just scanning a picture. So I painted mine with tar when I went. The technician never even looked at the scanned image (I don't know if they know how to.) And she never looked at my finger either.
I was prepared to say, "Keep you license" but I guess I only got a B+ in nonviolent protest. =-/
Great idea!
However, you had better be careful playing games with the license nazi's. You sign the form to get your license under penalty of perjury.
I don't know if masking your fingerprint is mentioned in the fine print anywhere, but it's a Class C Felony if you sign that it's complete and accurate and it turns out not to be.
