As more travelers pass through U.S. airports, many are noticing a shift in how the Transportation Security Administration (TSA) verifies passenger identities. Instead of just checking IDs and boarding passes by hand, the agency is increasingly using facial recognition technology.
But what exactly does that mean for your personal data, and should you be concerned? Let’s break it down.
How Facial Recognition Works at Airports
When you step up to the TSA security checkpoint at any of the 80+ airports currently using this system in US, a camera takes a snapshot of your face while your government-issued ID is scanned. This technology, known as the second-generation Credential Authentication Technology (CAT-2), uses biometric matching to compare your live image with the photo on your ID. It’s designed to verify your identity faster and more accurately, and it can also read digital IDs if you have one.
The goal, according to the TSA, is to ensure that the person boarding a flight is the same one listed on the travel documents. As stated by TSA Federal Security Director Gerardo Spero, this system improves the ability of officers to catch fake documents and validate passenger identities more effectively.
What Happens to Your Facial Data?
One of the biggest concerns travelers have is what happens to their facial image after it’s scanned. According to the TSA, if you’re a regular traveler who hasn’t enrolled in a special program like TSA PreCheck with touchless ID, your photo is deleted almost immediately after the check is completed. For PreCheck users who have opted into biometric screening, the data is erased within 24 hours of your flight’s scheduled departure.
Still, there are exceptions. TSA does conduct accuracy testing on its facial recognition systems from time to time. During these tests, your image may be kept temporarily, but the agency says it will post signs clearly letting you know if that’s happening — and you’re free to opt out of it. According to the TSA, opting out won’t affect your place in line or delay your screening.
Despite these reassurances, some privacy advocates urge caution. The core of the concern lies in what happens if that data is breached or misused. Even if facial images are only stored briefly, they are still part of a digital system that, like any system, could be hacked or compromised.
Are These Systems Really Secure?
No cybersecurity system is 100% secure. This applies to biometric systems as well. Experts point out that large-scale deployment of facial recognition systems creates new vulnerabilities.
If hackers were to gain access to any endpoint in the system — where the data is processed or stored — they could potentially access sensitive information, including your photo and ID data.
Can You Say No?
Yes, and the TSA emphasizes that you absolutely can. You don’t have to participate in the facial recognition process. If you’d rather not have your face scanned, you can simply tell the TSA officer, and they will perform a manual identity check instead. This choice won’t slow you down or get you flagged — TSA policy ensures that opting out doesn’t result in penalties or delays.
So, the next time you’re at the airport, it’s good to know you have a choice. You can use the automated system if you’re comfortable with it — or ask for the old-fashioned ID check if you’re not.
