If you're forced to do this in person with a tech, you can continuously "fight" the grip they have on your hand and smudge the card. However, they'll not submit the card until the prints are "good," so this sort of betrays your intent of at least appearing to cooperate with them. In the law enforcement community, they are taught how to take prints by force but it's unlikely that your tech will attempt any such technique.
I know of no such instance (other than some informal "fingerprint the kiddies for safety" schtick) where it's a do-it--yourself operation.
Not _technically_ perhaps. But in most cases it's a go-down-to-the-police-station-and-have-them-sign-the-card operation. Who is it that can tell a random signature from a police signature exactly? Like I said, standard print cards are available at the GPO.
While the methods listed are clever, they and many other finaglings are the main reason it's done in the "light of day" by a tech.
Or _theoretically_ done in the light of day by a tech.
You can mutilate the tips of your fingers so that prints cannot be acquired, but this hurts. Badly.
Doesn't always work. Partials can be extrapolated to yield a relative match.
Depends on what you are looking to do. If your goal is to deter random searching through a national database, mutilation will probably be very effective. If they have the prints of the murderer (you) and you're a suspect, mutilation aside from actually removing the fingers isn't going to do anything.
You could get some false latex coverings for your finger tips, but they'd have to be damn good to fool a tech. Likely to cost big bucks, too.
Wont work. The hands are checked first for signs of tampering.
See above about tech end around.
I know of no chemical or physical "pre-treatment" that can be used to hack the ink transference process. Perhaps one of the chemists here on the list might know of some good technique.
Pineapple juice and other weak acidic subtances ruin the ridges on the finger tips causing them to smear or not show at all. Unfortunately, this takes a period of time and constant handling of such items.
This is interesting. I suspect that you'd have to have major damage to the ridges however. --- My preferred and soon to be permanent e-mail address:unicorn@schloss.li "In fact, had Bancroft not existed, potestas scientiae in usu est Franklin might have had to invent him." in nihilum nil posse reverti 00B9289C28DC0E55 E16D5378B81E1C96 - Finger for Current Key Information Opp. Counsel: For all your expert testimony needs: jimbell@pacifier.com
