Short answer: Appendix F is the FBI's strictest image quality certification and the one livescan, applicant, and booking workflows need. PIV is a lighter single-finger specification for credential verification, not for fingerprint submissions. Mobile ID certifies smaller-format devices by FAP level for field use. If you submit fingerprints to the FBI or a state bureau, buy Appendix F. If you only verify a person against a card or database, PIV-class is enough. When in doubt, Appendix F covers the most ground: devices certified to it are also considered to meet the PIV specification.
What the FBI actually certifies
The FBI does not "approve scanners" in the loose way marketing copy suggests. Its CJIS division publishes image quality specifications (IQS), tests vendor devices against them, and lists passing products on the Certified Products List (CPL). Certification measures things like geometric accuracy, gray-level dynamic range, and signal-to-noise ratio: in plain terms, whether the image coming off the platen is faithful enough to match against millions of records.
Three program names matter when you are buying: Appendix F, PIV, and Mobile ID. Each entry on the CPL names the program and, where relevant, the FAP level (capture size class, which we break down in FAP Levels Explained).
Appendix F: the livescan standard
Appendix F belongs to the FBI's Electronic Biometric Transmission Specification (EBTS). It is the most stringent of the specifications, written so that captured prints hold up in human fingerprint comparison and large-scale one-to-many searches against the FBI's Next Generation Identification system. This is the certification behind every serious livescan device.
You need Appendix F if you are:
- running applicant or employment background check fingerprinting (livescan),
- submitting to a state identification bureau or FBI channeler,
- doing criminal booking with slaps and rolls,
- capturing prints for NFA eForms as an FFL (see our FFL setup guide).
Appendix F certification spans FAP levels: a two-finger Watson Mini (FAP 45) and a ten-print DactyScan84c (FAP 60) are both Appendix F devices. The program tells you the image quality bar; the FAP level tells you how much finger real estate it captures at once.
PIV: single-finger verification
The PIV specification (PIV-071006) came out of the federal Personal Identity Verification credentialing program. It is a single-finger image quality standard designed to support one-to-one verification: proving the finger on the platen belongs to the person the record says it does. The bar is real but lower than Appendix F, which is why PIV-only readers like the SecuGen Hamster Pro 20 are compact and inexpensive compared to livescan hardware.
PIV-class readers are the right buy for logical access, time and attendance, enrollment into verification databases, and SDK-driven applications. They are the wrong buy for anything that ends in a submission to a state or the FBI. A PIV reader cannot produce a compliant ten-print record no matter what software drives it.
One direction of substitution works: per the FBI's certification FAQ, devices certified to Appendix F are considered to have met the PIV specification. The reverse is never true.
Mobile ID: field capture by FAP level
Mobile ID certification covers portable identification devices, graded by FAP level (FAP 10 through 60) so agencies can match device capability to their field workflow. A patrol officer checking a subject against a warrant database might carry a FAP 10 or 20 unit; a mobile booking van wants FAP 45 or 60 with rolls. The certification framework is the same idea as Appendix F, applied to smaller capture formats with requirements scaled per level.
Buying note: several rugged mobile scanners, including the Integrated Biometrics line we carry, certify to Appendix F at their FAP level rather than only the Mobile ID profile, which keeps them eligible for applicant work as well as field identification. Check the exact CPL entry for the model you are considering.
Which certification do you need?
| Your workflow | Certification to buy | Typical device class |
|---|---|---|
| Livescan background checks, applicant fingerprinting | Appendix F | FAP 60 ten-print (Kojak, RealScan G10) |
| Criminal booking with rolls | Appendix F | FAP 60 ten-print or palm (CS500q) |
| NFA eForm fingerprinting at an FFL | Appendix F | FAP 60 or roll-capable FAP 45 |
| High-volume civil enrollment, slaps only | Appendix F | FAP 50 slap scanner (CS500f) |
| Field identification, mobile checks | Mobile ID or Appendix F at FAP 30 to 45 | Five-0, Watson Mini |
| Credential verification, access, time and attendance | PIV (or none, for closed systems) | Single-finger reader (Hamster Pro 20) |
How to verify a claim before you buy
- Get the exact model name and revision from the seller.
- Open the FBI's Certified Products List and search for the model.
- Read the entry: program (Appendix F or PIV), FAP level, and vendor. "FBI certified" with no program name is a red flag.
- Confirm the certification matches your workflow using the table above, not the seller's headline.
We make this easy on ourselves: every product page here names the program and FAP level, links the CPL, and we do not claim certification for anything not on the list.
Certification is not authorization
A certified scanner is necessary but not sufficient. To actually submit fingerprints you also need licensed capture software that formats transactions to EBTS, and an approved channel to the receiving agency. States run their own approval programs on top of FBI certification: California, Florida, and Texas each work differently, and we cover them in Livescan Requirements by State. If you are pricing a full setup rather than a bare scanner, start with our livescan cost guide or tell us your state and workflow and we will give you a straight answer.
