ATF Fingerprint Comparison Tables
Side-by-side comparisons for NFA applications
Quick Summary
Best fingerprint option for most NFA applicants: DIY EFT creation with SlapEFT. Cost: $10-20. Time: 15-20 minutes at home. Unlimited reuse for future applications. Professional LiveScan works equally well but costs more ($30-75) and requires travel.
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.
