What the TSA's Facial Comparison Technology page tells you — and what it quietly leaves out
The TSA's "Facial Comparison Technology" fact sheet presents facial recognition at airport checkpoints as routine, safe, and voluntary. It says participation is optional. It says photos are not stored. It says signage informs all travelers of their rights.
But the Government Accountability Office (GAO) found in 2023 that TSA had "not fully addressed transparency requirements for its facial recognition programs" — and that travelers frequently lack informed consent. Senators, journalists, privacy advocates, and ordinary travelers have documented cases where opt-out signage was invisible, agents denied the right to refuse, and travelers were threatened with police involvement for trying to exercise a right they officially have.
This guide reads the fine print so you don't have to guess.
Each panel below places a direct excerpt from the TSA fact sheet alongside what the available evidence — GAO reports, Privacy Impact Assessments, documented incidents — actually shows.
The most significant parts of the TSA fact sheet may be its silences. Here is what the document does not mention:
The document makes no mention of documented disparities in the technology's accuracy across different demographic groups. See Section 3 below for the full picture.
The document says participation is voluntary but gives no instructions for opting out. It does not say: tell the officer before your ID is scanned. It does not say: you cannot be penalized or delayed. It does not say: if an agent refuses, you have the right to ask for a supervisor.
The document does not mention the bipartisan Senate legislation introduced in 2023 by Senators Kennedy (R-LA) and Merkley (D-OR) that would require TSA to halt facial recognition and obtain congressional approval before re-deploying it. It does not mention GAO's finding that TSA has not complied with its own transparency requirements.
TSA Administrator David Pekoske stated publicly: "Eventually we will require biometrics across the board." The document presents current voluntariness as a principle, when TSA leadership has signaled it is a transitional stage. Today's opt-out may not exist tomorrow.
The National Institute of Standards and Technology (NIST) conducted the most comprehensive independent evaluation of facial recognition algorithms in 2019. Their findings directly contradict the TSA document's implicit assumption that the technology works equally for everyone.
| Demographic Group | Error Rate Compared to White Men | Risk Level |
|---|---|---|
| White men (baseline) | Baseline comparison | Lowest |
| Asian and African American faces | Up to 100× higher false-positive rates | Highest |
| Native American travelers | Highest false-positive rates of any group | Highest |
| Women (across demographic groups) | Consistently higher misidentification rates than men | Elevated |
| Older adults | Higher error rates than younger adults | Elevated |
A false-positive match does not simply create a minor inconvenience. It can result in additional screening, detainment, missed flights, and encounters with law enforcement. For travelers who are already subject to disproportionate scrutiny at security checkpoints, the technology compounds existing inequities. The TSA fact sheet mentions none of this.
Opting out is legal and, according to TSA's own policy, should not result in delays, additional screening, or lost place in line. Here is how to do it — in plain language, without the bureaucratic vagueness of the official document.
You have the right to opt out at any checkpoint where facial recognition is offered. You cannot be penalized, delayed, or denied boarding for doing so. You do not have to explain why. If you are a U.S. citizen at a domestic checkpoint, this right applies to you regardless of your race, background, or appearance.
Individual opt-outs are important. But the ethical failures documented in this guide are structural — they require policy change, not just personal action.
Opt-out rights must be communicated before travelers enter the scanning queue — not tucked between kiosks after the process has begun. Signs must be in multiple languages and placed at eye level where travelers can read them while standing in line.
TSA officers should be required to verbally inform every traveler of their right to opt out before the scan begins — not only when a traveler asks. Verbal notification is the only reliable way to ensure travelers have genuinely received the information.
The bipartisan legislation introduced by Senators Kennedy and Merkley (2023) would require TSA to halt facial recognition deployment and obtain congressional authorization before expanding further. Until NIST-documented racial and gender disparities are resolved, expansion compounds a proven harm.
TSA should be required to publish annual, publicly accessible reports on: the number of travelers scanned, the number who opted out, false-positive rates by demographic group, incidents of wrongful denial of opt-out rights, and the specific airports and contexts in which data is stored during testing phases.
TSA leadership has stated that mandatory biometrics are coming. Before this transition occurs, Congress — not the agency — should determine whether and how biometric identification may be made mandatory for domestic air travel, with full public hearings and civil liberties review.
