Biometric Processing & Digital Identity at Airports
Biometric processing—facial recognition, fingerprint scans, and iris scans—has moved from pilot programs to operational deployment at U.S. commercial airports across three federal programs and multiple private systems. TSA's Credential Authentication Technology (CAT-2) operates at approximately 80 airports and is expected to expand to 220+ locations; TSA PreCheck Touchless ID, launched at 15 airports in January 2026, provides hands-free identity verification for TSA PreCheck members and will expand to 65 airports by Spring 2026. U.S. Customs and Border Protection (CBP) operates the Biometric Entry-Exit Program using facial recognition to process over 100 million foreign nationals since FY 2018, with a final rule effective December 26, 2025 authorizing expanded biometric collection at all entry and exit points. CLEAR+, a private service, operates at approximately 60 airports. Delta Air Lines has deployed Digital ID at 11 airports; all major U.S. carriers now support TSA Touchless ID integration. State biometric privacy laws—particularly Illinois's BIPA—are driving data handling standards. Airport operators face capital investment decisions for checkpoint modifications to accommodate biometric lanes, cybersecurity obligations under TSA Security Directive SD 1580/82-2022-01, and lease revenue opportunities through CLEAR partnerships.

Overview
Biometric processing—the use of facial recognition, fingerprint scans, and iris scans to verify passenger identity—has moved from pilot programs to operational deployment at U.S. commercial airports. Three federal agencies operate biometric programs in the airport environment: the Transportation Security Administration (TSA), U.S. Customs and Border Protection (CBP), and, through its enrollment infrastructure, the TSA's PreCheck program. Private companies, including CLEAR and the major U.S. airlines, operate additional biometric systems under federal oversight or in partnership with these agencies.
TSA Credential Authentication Technology (CAT-2)
The CAT-2 unit is a TSA checkpoint device that performs three functions: (1) authenticates the traveler's physical identification document, (2) confirms the traveler's boarding pass and Secure Flight pre-screening status, and (3) performs a 1:1 facial match—comparing a live photograph of the traveler to the photograph on the presented credential.
Key operational details:
- Deployment: TSA has deployed CAT-2 units and is scaling facial recognition technology across the checkpoint network. As of December 2024, TSA reported facial recognition technology at approximately 80 airports, with expansion planned through the FY 2026 appropriations period.
- Data retention: The CAT-2 system does not retain personal passenger information, per TSA system requirements.
- Opt-out: Travelers may opt out of the 1:1 facial match and instead be processed by TSA based on a valid ID and boarding pass.
- Manufacturer: IDEMIA, under contract with TSA.
- Cost: TSA funds CAT-2 procurement and deployment through DHS appropriations.
CAT-2 replaces the earlier CAT-1 device, which authenticated documents but did not perform facial matching. The facial match capability addresses a longstanding vulnerability in manual document verification: human capability to match an unfamiliar face to a document photograph. According to the GAO's July 2022 assessment of CBP's facial recognition program (GAO-22-106154), biometric matching systems achieve higher accuracy rates on unfamiliar face-to-document comparisons than human reviewers relying on visual inspection alone.
TSA PreCheck Touchless ID
TSA PreCheck Touchless ID—also referred to as the Touchless Identity Solution (TIS)—is a next-generation identity verification system that allows eligible TSA PreCheck travelers to verify their identity at the checkpoint using facial matching, without presenting a physical ID or boarding pass.
How It Works
- A TSA PreCheck traveler opts in through a participating airline (Delta, United, American, Southwest, or Alaska Airlines) by adding valid passport information to their airline profile.
- The airline transmits a consent indicator on the traveler's mobile boarding pass.
- At a dedicated Touchless ID lane, a TSA officer with a tablet and high-definition camera captures the traveler's image.
- The system transmits the image to CBP's Traveler Verification Service (TVS) API, which matches it against the traveler's existing passport photo in the government database.
- If matched, the traveler proceeds. Images are encrypted and deleted within approximately 24 hours.
Current and Planned Deployment
| Metric | Status |
|---|---|
| Kiosks deployed (as of January 2026) | 45 next-generation TIS kiosks at 15 airports |
| Spring 2026 expansion | 65 airports total (50 additional locations) |
| Processing time | Under 10 seconds per traveler |
| Speed improvement | 66% faster than standard PreCheck processing, based on TSA internal testing data |
| Participating airlines | Delta, United, American, Southwest, Alaska |
| Eligibility | TSA PreCheck enrollment + valid U.S. passport |
Current airports include Atlanta (ATL), Dallas Fort Worth (DFW), Chicago O'Hare (ORD), Denver (DEN), Detroit (DTW), Las Vegas (LAS), Los Angeles (LAX), Newark (EWR), New York JFK and LaGuardia (JFK/LGA), Phoenix (PHX), Salt Lake City (SLC), San Francisco (SFO), Seattle (SEA), and Reagan National (DCA). The Spring 2026 expansion will bring TSA PreCheck Touchless ID to 50 additional airports nationwide, including major hubs and high-traffic facilities.
