By 2026, facial recognition scanners are running at more than 350 U.S. airports, scanning travelers by default at the checkpoint before most people have even found their boarding pass. Almost none of them are told they can say no.
They can. That's the part TSA doesn't put on a sign.
Two Systems, Two Sets of Rules
TSA actually runs two separate facial recognition programs, and the distinction matters. The general checkpoint system uses CAT-2 scanners that capture your face and compare it against the photo on your ID or passport in real time, for identity verification. TSA's policy states these images are deleted immediately after the match. The second system, Touchless ID, is reserved for TSA PreCheck members and compares your face against government databases including passport photos — and unlike the general system, it retains images for 24 hours to allow scanning at multiple checkpoints during a single trip. Touchless ID is now active at more than 65 major airports and supported by all five major U.S. airlines.
Both systems share one thing: TSA describes participation as voluntary. In practice, almost nobody is told that before they step up to the scanner.
The Expansion Nobody Voted On
None of this went through Congress as a standalone, debated policy. It expanded checkpoint by checkpoint, airport by airport, framed each time as a convenience upgrade — shorter lines, no fumbling for a boarding pass, "touchless" travel in the name of both speed and post-pandemic hygiene. DHS has separately floated expanding face-scanning requirements to cover U.S. citizens more broadly at the border, not just the foreign nationals the original biometric exit programs were built around — a scope expansion privacy advocates have been warning about since these programs were first piloted.
The practical effect is a biometric checkpoint that's become the default experience for the large majority of travelers who never hear the word "optional" spoken out loud, layered on top of an identity-verification process that used to just involve a person looking at your face and your ID and deciding if they matched.
What Opting Out Actually Looks Like
Here's the part that surprises people: opting out is simple, and TSA's own policy says you face no penalty for doing it. You don't need a form, a lawyer, or advance notice. You tell the officer, before your ID goes into the scanner, that you'd like to opt out of facial recognition and be verified manually instead. Phrases like "I opt out of the face scan" or "I'd like manual ID verification" are enough. An officer checks your ID and boarding pass by hand, the way it worked before any of this existed.
The friction is social, not procedural — saying it out loud, holding up the person behind you for an extra fifteen seconds, wondering if it'll draw extra scrutiny. It won't, by TSA's own stated policy. The scanners are fast specifically because almost nobody exercises the option that's already sitting right there.
The Part That Doesn't End at the Checkpoint
Opting out of the scan solves the checkpoint problem. It does nothing about the data ecosystem around your trip. Hundreds of data brokers maintain files linking your name to your address, phone number, financial history, and travel patterns — assembled from airline bookings, loyalty programs, and the same commercial data-broker pipeline covered elsewhere on this blog. Declining a face scan doesn't erase the fact that your flight, your seat, and your frequent-flyer number already tell a fairly complete story about where you go and when.
What You Can Actually Do
- Say the words before your ID goes in the scanner. Waiting until after means you've already been scanned. "I'd like to opt out of face recognition" is all it takes.
- Know the difference between the two systems. If you're a PreCheck member, you can decline Touchless ID specifically while still using PreCheck's expedited screening — it's a separate enrollment, not a package deal.
- Ask what happens to the image if you don't opt out. TSA's policy says checkpoint images are deleted immediately; Touchless ID images are retained for 24 hours. You're entitled to ask an officer to confirm which system you're facing.
- Treat this as one piece of a bigger picture. Pair opting out at the checkpoint with broader data-broker opt-outs — the scan is the most visible part of airport surveillance, not the only part.
The Other Side
TSA and the airlines backing Touchless ID argue the technology measurably speeds up checkpoints and reduces the human error that comes with manually comparing a photo ID to a tired traveler's face at 5 a.m. — a real problem the old system genuinely had. They point to the immediate-deletion policy for the general system as a meaningful privacy safeguard, and note that biometric identity verification is already standard at international border crossings in dozens of countries.
Critics counter that "voluntary" programs where almost no one is informed of the option function as mandatory ones in practice, and that "deleted immediately" is a policy promise, not something travelers can independently verify at the moment it matters. The push to extend face-scanning requirements to U.S. citizens at the border, not just visiting foreign nationals, is the specific expansion privacy groups say crosses a line — turning a narrow biometric-exit tool aimed at visa compliance into a general-purpose citizen identification system, one checkpoint at a time.
