As mentioned above, the ATF will send you the cards for free, and pretty quick. Just don't forget you ordered them or the huge envelope in the mail with BATF all over it will make your heart stop. I've sent my own in on my last 4 applications. I sent 1 kinda rough one, just to see if they'd kick it back, they didn't. I really feel like if it were that important, you'd have to go to their place and prove who you are and let them take the prints, just like for other government agencies. Good luck.
