ATF Fingerprint Comparison Tables

Side-by-side comparisons for NFA applications

DIY EFT vs Professional LiveScan

Two main options exist for creating ATF fingerprint files:

Factor DIY EFT (SlapEFT) Professional LiveScan Winner
Total cost $15-25 $30-75 DIY
Time required 15-20 min at home 30-60 min (travel + appt) DIY
Scheduling Anytime (24/7) Business hours only DIY
Location At home UPS Store, IdentoGO, etc. DIY
Equipment needed Scanner, ink pad, FD-258 None (provided) LiveScan
Technique required Basic rolling technique None (technician handles) LiveScan
Quality ATF-compliant ATF-compliant Tie
Reusable? Yes, unlimited Yes, unlimited Tie
Privacy High (you control data) Lower (third-party) DIY

Verdict

DIY is better for most people. Cheaper, faster, more convenient. Choose LiveScan if you have no scanner or prefer professional handling.

Fingerprint Format Comparison

All US government fingerprint formats are based on ANSI/NIST-ITL:

Feature EFT (ATF) EFTS (FBI) EBTS (DoD)
Full name Electronic Fingerprint Transmission Electronic Fingerprint Transmission Specification Electronic Biometric Transmission Specification
Primary user ATF FBI, civilian agencies DoD, military
Base standard ANSI/NIST-ITL ANSI/NIST-ITL ANSI/NIST-ITL
Typical resolution 500 DPI 500 DPI 500-1000 DPI
Max file size 12 MB Varies Often larger
Biometrics included Fingerprints only Fingerprints, sometimes photos Fingerprints, iris, facial
ATF compatible? Yes (native) Yes (with conversion) Yes (with conversion)
Common extensions .eft, .nst .efts, .nst .ebts

Key Insight

All formats can be converted to ATF EFT. The core biometric data is compatible. Conversion adjusts metadata and optimizes file size.

Type-4 vs Type-14 Fingerprints

NIST files can contain different fingerprint record types:

Feature Type-4 (Rolled) Type-14 (Flat/Slap)
Capture method Roll finger nail-to-nail Press finger flat
Coverage Full fingerprint width Central area only
Detail level Higher (more area) Standard
Technique required More (rolling skill) Less (just press)
Common source Ink cards, older LiveScan Modern LiveScan
ATF accepted? Yes Yes
Best for DIY with ink cards Professional LiveScan

Verdict

Both work equally well for ATF. Use whatever your capture method produces. Most LiveScan services output Type-14; ink cards typically produce Type-4.

Fingerprint Conversion Tool Comparison

Three main options for converting fingerprint files to ATF format:

Feature SlapEFT OpenEFT EFT Suite
Cost $10 per conversion Free Free
Technical setup None (web-based) Docker required Docker required
Time to start Instant 30-60 min setup 30-60 min setup
Technical skill needed Basic (upload file) Intermediate (command line) Intermediate (command line)
Known bugs N/A Some (community maintained) Yes (GitHub issues)
Support Email support Community/GitHub GitHub issues only
Card scanning Yes No Limited
NIST conversion Yes Yes Yes
Best for Non-technical users Developers Developers

Verdict

SlapEFT for most users. The $10 cost saves hours of technical setup. Free tools work but require Docker knowledge and troubleshooting.

Time-to-Value Analysis

SlapEFT: 2 minutes (upload → download)
OpenEFT/EFT Suite: 30-60 min setup + troubleshooting

If your time is worth more than ~$10/hour, SlapEFT is more economical.

Fingerprint Source Comparison

Can you reuse existing fingerprints? Comparison of sources:

Source Can You Get File? Difficulty Recommendation
Create new (DIY) Yes Easy Best option for most
LiveScan service Yes (at time of service) Easy Good option
Previous LiveScan Maybe Medium Try vendor first
CCW permit Maybe Medium Contact fingerprint vendor
Professional license Maybe Medium Contact fingerprint vendor
TSA PreCheck Unlikely Hard Create new instead
Global Entry Unlikely Hard Create new instead
FBI background check Unlikely Hard Create new instead
Military (MEPS) Very unlikely Very hard Create new instead
Security clearance Very unlikely Very hard Create new instead

Rule of Thumb

If you can get the file in under 10 minutes, it's worth trying. Otherwise, creating new fingerprints ($10, 15-20 min) is faster and easier.

Complete Cost Comparison

Total costs for different fingerprint methods:

Method First-Time Cost Per Additional NFA Item Notes
DIY + SlapEFT $15-25 $0 Includes supplies + conversion
Convert existing file $10 $0 If you already have NIST file
Professional LiveScan $30-75 $0 Varies by provider/location
Gun store service $25-50 $0 Some offer EFT direct
OpenEFT/EFT Suite $0 + time $0 Requires technical setup

Cost Per NFA Item (Multiple Applications)

NFA Items DIY Cost per Item LiveScan Cost per Item
1$20$50
2$10$25
5$4$10
10$2$5

Verdict

DIY is most cost-effective, especially for multiple NFA items. The same EFT file works forever at no additional cost.
