Electronic Fingerprinting Services
Digital fingerprint capture for your ATF NFA applications
Every ATF NFA application — a Form 4 to transfer a suppressor or SBR, or a Form 1 to build your own — requires fingerprints from every responsible person involved. You have two options: old-school ink-and-paper FD-258 cards, or a digital .EFT file that uploads directly into your ATF eForms application. No ink, no mess, and no rejected fingerprint cards.
K3 Armory only files with .EFT electronic prints. We capture your fingerprints digitally, right here at our Midlothian, VA location near Chesterfield, Moseley, Amelia, Chester and Richmond. You’ll receive an ATF-compliant .EFT digital file ready to go — no mailing, no smudged cards, no delays waiting on a rejected submission.

How the fingerprinting process works
The ATF requires fingerprints from every responsible person on an NFA application. You have two options: old-school ink-and-paper FD-258 cards (required for paper applications mailed to the ATF), or a digital .EFT file that uploads directly to your ATF eForms application.
K3 Armory only files NFA forms with electronic fingerprints. But we make the process of scanning your prints and creating your .EFT digital file as easy as possible.
Buy it on its own, or add it to your NFA transfer or Form 1 paperwork order.
Book a dedicated fingerprinting appointment, or combine it with your existing NFA paperwork appointment — your choice.
Takes about 15 minutes, in-store, with no ink involved.
You’ll get an ATF-compliant file ready to upload to your eForm 1 or eForm 4 — or if we’re handling your eForm submission, we upload it for you.
Your .EFT file is reusable for life — store a backup copy somewhere safe, and you’re set for every future NFA application.
