Can You Opt Out of Facial Recognition at the Airport?

Three airports. One bullet train station. A U.S. immigration app. Discord. All in one week. Facial recognition didn't just have a moment this week — it had a sprawl. And buried inside that sprawl is a story that should make every professional who uses facial comparison technology stop and think carefully about what "mainstream" actually means.

This is not a story about facial recognition becoming more trustworthy. It's a story about facial recognition becoming more common. Those are not the same thing, and confusing them is exactly how professional reputations get damaged.

Facial Recognition Deployment: Everywhere, All at Once

Start with the travel sector, because that's where the acceleration is most visible. The TSA launched a second facial recognition trial at Harry Reid International Airport in Las Vegas, according to FEDagent — building on existing deployments at airports across the country. Meanwhile, Alaska Airlines rolled out facial ID verification at automated bag drop units in Seattle and Portland, per an Alaska Airlines announcement, letting passengers check bags without interacting with a human agent. Your face handles it. Efficient. Fast. Frictionless.

Across the Pacific, Panasonic Connect announced a trial of facial recognition ticket gates at JR East's Joetsu Shinkansen Nagaoka Station — meaning Shinkansen passengers could soon board bullet trains using nothing but their face as a ticket. No card. No QR code. Just walk through. The New York Times, for its part, ran a feature this week on how check-in counters across the travel industry are increasingly treating your face as your primary ID.

Look at that list again. Airport security. Bag drop. Train stations. The same technology, deployed nearly simultaneously across multiple countries and multiple transport contexts. If you were watching from the outside, you'd be forgiven for thinking facial recognition had been certified, standardized, and cleared for high-stakes identity use. You'd be wrong. This article is part of a series — start with Eu Ai Act Facial Recognition 2026.

Facial Recognition Accuracy: The Untold Story

Here's where it gets interesting. The same week all those deployment announcements landed, WIRED published an investigation finding that a facial recognition app used by ICE and CBP — a U.S. government immigration enforcement tool — cannot actually verify the identity of the people it scans. Not "sometimes struggles with." Cannot. The system collects faces. It does not reliably confirm who those faces belong to. That distinction — between capturing biometric data and verifying it — is the whole game, and apparently one of the government's own identity tools has been conflating the two.

That's not a minor technical footnote. That's a deployed enforcement tool being used to make consequential decisions about real people, built on a verification gap its own operators may not fully understand.

Then there's the Discord story. Fortune reported that Discord publicly distanced itself from a Peter Thiel–backed age and identity verification software after code from the tool was discovered on a U.S. government website. A gaming and social platform deciding it doesn't want its name anywhere near a government-adjacent biometric verification product — in the same week governments are expanding biometric checkpoints at every transit node — says something. Platforms are reading the room even as agencies are not.

The Legal Scholars Are Getting Louder

It isn't just technologists raising flags. Legal scholars writing for The Regulatory Review have been explicit about the traveler rights questions that TSA's expanding facial recognition program leaves unanswered. The core issue: when a traveler declines to participate in biometric scanning at a checkpoint, what actually happens? How is that declination documented? What are the consequences — formal or informal — of opting out? These are not hypothetical concerns. They are operational realities that the current legal framework has not resolved.

"The TSA has not always been transparent about how facial recognition technology works, who can access biometric data, how the data is stored, and how long it is retained — information travelers need to make informed decisions about whether to consent to the scans." — The Regulatory Review

That's a remarkable sentence to read alongside news of TSA's Las Vegas expansion. The agency is scaling up deployments while, by the account of legal scholars, still not being transparent about basic data handling with the public being scanned. Ubiquity, again, doing the work that transparency hasn't done. Previously in this series: Face As Id Goes Mainstream Accuracy Hasnt Kept Up.

Can You Opt Out of Facial Recognition at the Airport?

Yes — at TSA checkpoints in the United States, TSA facial recognition is optional for domestic travelers. You can opt out of the face scan and ask the officer for a standard ID check instead. This has been true at every checkpoint where the agency has deployed the technology, including the newer trial locations covered above, and it remains true as the program expands to more airports.

How Do You Opt Out of the TSA Face Scan?

The opt out process is simple in theory: tell the TSA officer at the travel document checking station that you don't want your photo taken, before the camera captures your face. Signage near the podium is supposed to notify travelers that the facial scan is optional, though legal scholars quoted above note that TSA has not always been clear about this in practice. Travelers who opt out still go through standard identity verification — an officer manually checks your ID and boarding pass instead of relying on facial matching.

Does Opting Out Slow You Down at the Airport?

Sometimes, yes. Manual ID checks can take a little longer than an automated facial scan, especially at a busy checkpoint during peak travel hours. Travelers who are anxious about wait times or connecting flights should factor that into the decision, but the extra time is generally measured in seconds to a couple of minutes, not a meaningful delay to the overall security line.

What About Facial Recognition at Bag Drop and Boarding Gates?

Airline-operated facial ID systems, like the Alaska Airlines bag drop units described above, are a separate system from TSA's checkpoint face scan, and opt out rules can differ by airline and by airport. In most cases travelers can still ask a human agent to check a photo ID and boarding pass the traditional way instead of using the face scanning kiosk. If you have privacy concerns about a specific airline's facial recognition step, ask a gate agent directly what the non-biometric alternative identity check looks like before you reach the machine.

Why Do Some Travelers Choose to Opt Out?

Privacy is the most common reason. Some travelers don't want their face added to a government or airline database, or they're uncertain how long that photo will be retained or who else can access it — concerns the Regulatory Review scholars quoted above say TSA has not fully addressed. Other travelers simply prefer human interaction over face scanning technology at a checkpoint. Either reason is valid, and opting out does not require travelers to explain themselves to TSA staff.

Facial Recognition Deployment: Professional Impacts

Look, nobody's saying facial comparison technology doesn't work. It does — when it's used correctly, with controlled inputs, documented methodology, and explainable outputs. The problem this week's news creates is more subtle than a technology failure. It's a credibility pollution problem.

When governments deploy facial systems at scale — airport gates, immigration apps, train stations — those systems are optimizing for throughput. They're designed to process thousands of comparisons quickly, and their accuracy metrics are system averages across massive volumes. A 99% accuracy rate sounds excellent until you're the 1% at an international border crossing. Or until you're an investigator whose case hinges on a facial comparison that a defense attorney can now point to and say: "Isn't this the same technology that WIRED reported can't actually verify identity?"

That's the accountability imbalance that matters here. When an airport facial gate produces a false positive, a passenger gets delayed and frustrated. When an investigator presents a flawed facial comparison in an insurance fraud case, a custody dispute, or a corporate investigation, the consequences are professional liability, case dismissal, or worse. Government risk tolerance is not investigator risk tolerance. Full stop.

This is exactly why the methodology behind professional face comparison has to be something you can walk into any room and explain from first principles — the image quality controls, the lighting consistency, the comparison logic, why the result means what you say it means. Not "a government agency uses something like this, so it must be fine." That argument doesn't survive cross-examination. It barely survives a skeptical client call.

The rapid normalization of facial tech in travel and transit does create one genuine professional benefit: clients and juries are increasingly familiar with the concept of facial comparison as a real investigative tool. That's not nothing. But familiarity without scrutiny is exactly what produced an ICE/CBP app that couldn't verify the identities it claimed to verify, and a TSA expansion program that legal scholars say still hasn't answered basic transparency questions about data retention. Up next: Super Recognizers Facial Comparison Scores.

The real lesson from this week's headlines isn't about whether facial recognition is good or bad. It's about what "validated" actually means in your specific professional context. A Shinkansen trial at Nagaoka Station and a TSA checkpoint at Harry Reid Airport don't validate your methodology. Your methodology validates your methodology.

So here's the question worth sitting with: when you see governments and travel hubs adopting facial tech at this speed, does it make you more confident reaching for facial comparison in your own cases — or does it make you more rigorous about documenting exactly why your approach doesn't share the same weaknesses that WIRED just exposed in an immigration enforcement app?

Because if the answer is "more confident" without any of the second part, this week's news just handed opposing counsel a very useful argument.

For travelers wondering whether face scan participation is mandatory, the short answer stays consistent across every airport mentioned in this piece: TSA facial recognition is optional, and travelers retain the right to a manual ID check instead. That right does not disappear as TSA facial recognition expands to Harry Reid International Airport or any future location; the opt out option is part of the program's stated design, even where signage and staff communication about it could be clearer.

Travelers who care about privacy should also think about the photo itself. A facial scan captures a live photo at the checkpoint, compares it against a reference photo on file such as a passport or ID photo, and — depending on the system — may or may not retain that live photo afterward. Understanding what happens to that photo, and for how long, is part of making an informed decision about whether to participate.

It helps to separate the two different travel contexts covered in this article. TSA facial recognition governs the security checkpoint and identity document check, while airline-operated systems like the Alaska Airlines bag drop units govern boarding and baggage steps. Both are optional in practice, but travelers need to ask about the alternative at each step separately, since one opt out does not automatically cover the other.

Some travelers assume that opting out will draw unwanted scrutiny or slow them down at security. In practice, a manual ID check by a trained officer is a well-established alternative identity verification method that predates facial scanning technology entirely, and it remains a normal, permitted path through the checkpoint. Choosing it is not unusual, and it does not require a traveler to justify their privacy choices to staff.

Frequent travelers who want to plan ahead can look for posted signage at the travel document checking station, which is meant to flag that the face scan step is optional before a photo is taken. If signage is unclear or missing, simply telling the officer you'd like to opt out before stepping up to the camera is enough to trigger the manual process instead.
