How to Get an EFT File for ATF eForms

Every ATF eForm 1 and eForm 4 submission needs a set of fingerprints, and the ATF eForms portal takes them as a single EFT file. There are three common ways to produce that file: roll an FD-258 card and convert it yourself at home, visit a third-party livescan location, or use a fingerprinting kiosk at a participating gun shop. All three work. They differ in cost, speed, privacy, and what your options are when a print comes out bad. This guide walks through each path, puts them side by side, and calls out when each one is the right choice.

The three options in one sentence each

DIY with SLAP & ROLL. Roll an FD-258 at home (or bring one already rolled at a police department or sheriff's office), scan it on any 500+ DPI flatbed scanner, and generate the EFT file in your browser. $20 per file. An EFT file stays valid across submissions as long as your biographic data doesn't change, so most individual applicants pay once and reuse the same file for every eForm they ever file.
Third-party livescan. Drive to a dedicated livescan location - a shipping shop, a fingerprinting service, or a similar outlet - and have your prints captured on their electronic sensor. The file is typically emailed to you within an hour; busy locations or queued jobs can push that to a few hours or, occasionally, days. Typically $55–85.
Kiosk at a gun shop. A small number of FFLs install a dedicated fingerprinting kiosk. Most are self-service: you swipe a card, follow the prompts on the screen, and place your fingers on the sensor yourself. Many kiosk vendors in the NFA space do not hand the customer a portable EFT file. The file is retained on the vendor's servers and routed into the vendor's own eForms workflow, which you either use or work around. Other vendors differ. Customer pricing depends on the shop; $0–40 per file is the common range.

There is also a fourth, older path - mail-in conversion services - covered briefly at the end of this guide. It is a distant fourth on cost and speed and is shrinking as a category.

Cost

	DIY with SLAP & ROLL	Third-party livescan	Kiosk at an FFL
Per-file price	$20	$55–85	$0–40
Equipment you supply	Flatbed scanner + ink pad + FD-258 card	None	None
One-time equipment cost	$0 if you own a scanner; $80–150 if not	$0	$0
Consumables	~$5 cheap pad, ~$2-3 for some FD-258 cards (or free printable)	None	None
Travel	None	Round trip to location	Round trip to participating shop

A few specifics most comparisons skip:

If you already own a flatbed scanner, DIY with SLAP & ROLL is the cheapest path - $20 versus $55–85 at a third-party livescan, and no time away from your desk. Most applicants already own a scanner through a multifunction printer, or can use a friend's scanner/printer combo.
If you don't own a scanner, a budget flatbed runs $80–150 and handles 600 DPI easily. A one-time $90 hardware cost plus the $20 file exceeds a single $65 livescan visit, so DIY is not the cheapest path if you're buying a scanner specifically for this. What DIY gets you over livescan at that price point is the rest of the page: no drive, no appointment, no vendor-held data, and a scanner you keep for everything else.
One EFT file generally lasts forever. An EFT file stays valid across submissions until your biographic data changes or the ATF adopts a different format. An individual applicant filing several eForm 1s or eForm 4s over the course of a year does not need several EFT files; they pay $20 once to generate the file and attach the same file every time. The exception is a trust with multiple responsible persons: each person needs their own EFT file.
If you're an FFL considering offering this service in-shop rather than sending customers to livescan, see our dealer guide. A kiosk runs $2,000–5,000 up front; SLAP & ROLL Pro is built for dealers generating files for multiple customers.

Speed

	DIY with SLAP & ROLL	Third-party livescan	Kiosk at an FFL
Time in the seat	5–10 min at home	15–30 min + travel	5–15 min + travel
Time to EFT file in hand	Instant	Typically ~1 hour by email; occasionally hours or days	Instant in-shop (if the vendor gives you the file - see Privacy below)
When can you do it	Any time	Business hours, often by appointment	Shop hours
Second trip if a print fails	No (re-upload for free)	Usually no (operator re-captures on the spot)	No (self-service re-capture, as long as the sensor cooperates)

DIY wins on speed. You can generate an EFT file at 11pm on a Sunday, upload it to the eForms portal from your laptop, and the submission is logged before business hours the next day. Livescan is fastest in-person but variable on delivery: most locations email the file within an hour, some take a few hours, and the occasional backlogged location takes days. Kiosks are as fast as DIY if a shop near you has a working one and it's open.

None of the three affects ATF processing time once the eForm is submitted. The bottleneck is always the reviewer, not the file format. What the method affects is how long it takes you to get to the "file submitted" step in the first place.

Privacy

This is where the three paths diverge the most, and it is the axis readers tend to think about least until they read the fine print.

DIY with SLAP & ROLL. The scanned card image uploads to our servers so we can detect and crop the twenty fingerprints on it. The biographic fields - SSN, full name, date of birth, address - never leave your browser. Since the biographic record is generated digitally inside the web app, you do not even need to fill out the biographic fields at the top of the physical paper card. The EFT file is assembled entirely in your browser, and you can verify this yourself by disconnecting from Wi-Fi after the crops load and watching the Generate click produce zero outbound network requests. Card images on our servers are encrypted at rest and auto-deleted after 30 days, and you can delete them manually from your dashboard at any time.
For a step-by-step walkthrough of this privacy flow, including the offline-generation check, see How to convert an FD-258 fingerprint card to an EFT file at home.
Third-party livescan. The operator captures your fingerprints and biographic data on their system and produces the EFT file from their records. Retention varies by vendor and is not always disclosed. If privacy matters to you, ask before you book: how long is my data retained, and is it retained on a local system or a cloud service.
Kiosk at an FFL. Many kiosk vendors in the NFA space do not hand the customer a portable EFT file. Your prints and biographic data are captured on the vendor's hardware and retained on their servers; the vendor then routes the file into their own eForms workflow rather than giving you a .eft file you can attach to any eForm anywhere. Some kiosk vendors behave differently and do give the customer the file directly. Before you put your fingers on the sensor, read the vendor's terms and ask if you'll actually receive your own portable EFT file. Most of the time you are vendor-locked; they retain your prints and biographic data on their systems so you are forced to submit through their workflow, rather than giving you a file you can use anywhere.

Quality control - what happens when a print comes out bad

Every path has a quality-failure mode. How each one handles it is different.

DIY with SLAP & ROLL. The quality check runs before you pay. Upload the scanned card, and within seconds SLAP & ROLL detects the twenty prints on it and scores each one using the FBI's NFIQ algorithm - NIST Fingerprint Image Quality, a standardized 1–5 score where 1 is excellent and 5 is poor. You see a per-finger NFIQ score on the analysis page. If the Create EFT button is available, the card is good enough to generate a file. Re-uploads are free, so you can iterate on prints before spending a dollar.
For a full explanation of what the 1–5 score measures and what score to aim for, see Understanding NFIQ scores.
Third-party livescan. An operator re-captures a failed print on the spot. Quality feedback comes automatically from the capture software on their terminal. You do not typically see a per-print NFIQ score.
Kiosk at an FFL. Kiosks are typically self-service: you place your fingers on the sensor and re-capture yourself when the software flags a bad read. Quality indicators vary by vendor. Sensor sensitivity also varies, and if the scanner hardware or kiosk sensor isn't maintained well, it can be extremely frustrating to get successful scans. It is not unheard of for people to spend 15–20 minutes trying to get the sensors to register their fingerprints properly, especially if the sensor is dirty, sticky, or if the applicant has dry or worn fingertips.

On what actually matters: the ATF eForms portal does not currently reject submissions based on NFIQ score, so imperfect prints generally go through regardless of which path produced them. Aim for high quality anyway. Policy can change, the FBI matcher still prefers clean ridge detail, and a clean card today is cheap insurance against a re-roll later. Where DIY's free pre-pay check earns its keep is the cost-free iteration loop - you can upload, read the scores, re-roll problem fingers, and upload again at no charge. Livescan and kiosk workflows fix problems at the counter too, but if a print slips through, your only recourse later is a fresh capture (and, on livescan, a fresh fee).

Availability

DIY with SLAP & ROLL. Anywhere with a flatbed scanner and an internet connection. No appointment, no business hours, no geography.
Third-party livescan. Depends entirely on where you live. Suburban and urban readers usually have a location within 15–30 minutes. Rural readers often have none within an hour. If your nearest livescan is a round-trip drive longer than it takes to file the whole eForm, it is not a realistic option.
Kiosk at an FFL. A few thousand gun shops in the country have a fingerprinting kiosk installed. Finding one within reasonable distance depends on whether an FFL near you has made the investment. Call ahead - kiosk availability and kiosk uptime are separate questions.

If you are the applicant and no livescan exists within a reasonable drive, the choice simplifies. DIY is not "the best of three options" for you; it is the realistic option. The same is true, in reverse, for dealers: if your customers are in that situation, offering EFT conversion at your counter is a service nobody else in your area can provide.

The card someone else rolled

A detail that comes up often and changes the comparison: some police departments and sheriff's offices will roll an FD-258 for you at low or no cost if you walk in and ask. If you arrive home with a finished card in hand:

DIY with SLAP & ROLL handles it directly. Scan the card, upload it, check the quality, and generate the EFT. No rolling on your end. This is the lowest-effort version of the DIY path.
Third-party livescan cannot use your existing card. Livescan is a live capture; the operator re-rolls your prints on their equipment.
Kiosk cannot use your existing card either. Same reason - live capture only.

The card-from-a-sheriff path is a DIY-only shortcut worth knowing about.

The EFT file itself, on any of the three paths, is the same kind of file - built to the FBI's EBTS (Electronic Biometric Transmission Specification), the format the ATF eForms system accepts. The ATF portal does not distinguish files by source; it validates the file format. A DIY-generated EFT file and a livescan-generated EFT file are equivalent inputs to the eForm.

What about mail-in conversion services?

A fourth path exists: mail your completed FD-258 card to a conversion service, they scan it and generate the EFT file, and they email it back. Historically this filled the gap for applicants with no livescan nearby and no at-home scanner. It is slower and costlier than DIY on every axis:

Cost: $25–40 per file, plus postage, plus time. More than SLAP & ROLL's $20.
Speed: Days at a minimum. A weekend of transit plus processing plus return mail.
Privacy: The mail-in service holds your completed card (with your rolled prints) and produces the EFT file on their infrastructure. Retention terms vary.
Quality control: You learn whether a print was too light or smeared after the service has already processed the card.

Mail-in services were the DIY category before DIY existed. If you already own a scanner, there is no remaining reason to use one.

Common questions

Will the ATF accept a DIY-generated EFT file?

The ATF eForms portal validates the file format, not the source. An EBTS-compliant EFT file is accepted regardless of whether it came from a home scanner, a livescan station, or a kiosk. The format is the gate - not the vendor.

Do I need a new EFT file for every eForm you submit?

No. An EFT file is a snapshot of your fingerprints and biographic data, and it stays valid across every submission as long as that data is current. A single $20 file covers one responsible person for as many eForm 1s and eForm 4s as they ever file. If your name or address changes later, use our free editor to update the file rather than re-rolling prints.

Will poor-quality prints get my eForm rejected?

The ATF eForms portal does not currently reject submissions based on NFIQ score, so imperfect prints generally go through regardless of which path produced them. The FBI matcher still prefers clean ridges, and policy can change, so roll as clean a card as you can manage. If SLAP & ROLL lets you click Create EFT, your card is good enough for today's rules.

Do I need to be tech-savvy to DIY?

No. It is a web page. Upload a scanned image, see the quality check, click to generate, save the file. If you have ever attached a photo to an email, you have the skills.

Is rolling my own prints hard?

Not really. A clean flat surface, a standard ink pad, and fifteen minutes of patience will produce a card most applicants get right their first try. If you want to practice, see How to roll your own fingerprints on an FD-258 card.

My scanner is 300 DPI. Can I use it?

No. 500 DPI is the NIST-published minimum resolution for automated fingerprint matching. SLAP & ROLL flags scans below that before you pay, and the FBI matcher can't reliably extract ridge detail from them anyway. Budget 600-DPI flatbed scanners are $80–150.
