U.S. airports continue to adopt biometric facial recognition technology as part of a nationwide effort led by U.S. Customs and Border Protection (CBP) to modernize travel security and streamline identity verification at international entry and exit points. Recent deployments at San Jose International Airport (SJC) and Omaha’s Eppley Airfield illustrate the growing scale and sophistication of this program.
At SJC, facial biometric systems are now fully operational for all international arrivals and departures, covering every gate that serves international flights. The deployment, conducted in partnership with CBP, builds on a 2018 pilot program that made SJC the first West Coast airport to trial CBP’s facial recognition initiative. At checkpoints, passenger images are captured and matched against passport or visa records in government databases to verify identity with minimal delay.
Similarly, Omaha’s Eppley Airfield has become the latest airport to adopt CBP’s facial comparison technology, which captures a live image of arriving travelers and matches it to stored government records. This implementation is part of CBP’s broader Biometric Entry-Exit Program, which now spans 238 U.S. airports. The agency reports more than 98 percent accuracy in facial recognition identity verification, although accuracy can vary based on lighting, algorithm performance, and demographic factors.
CBP has also piloted the use of facial biometrics at land border crossings and maritime ports, with cruise terminals reporting processing time reductions of up to 30 percent. These technologies form part of a broader trend toward contactless travel infrastructure, a priority accelerated by the COVID-19 pandemic as airports worldwide seek to minimize touchpoints and improve efficiency.
CBP emphasizes that biometric data is encrypted, stored securely, and subject to retention limits. Photos of U.S. citizens are deleted within 12 hours of verification, while images of non-citizens may be retained for up to 14 days or longer under certain DHS programs. U.S. citizens also have the right to opt out by requesting manual document verification from CBP officers. However, privacy advocates note that opt-out options are not always clearly communicated and are unavailable to most foreign nationals.
Privacy concerns surrounding the program have drawn criticism from civil liberties groups, particularly over the lack of comprehensive federal regulations governing biometric data use by law enforcement. Ongoing legal challenges have questioned biometric data sharing practices, especially involving non-citizens. While CBP asserts that it complies with internal privacy policies, critics have cited prior incidents—such as the 2019 breach of biometric data via a CBP subcontractor—as evidence that more robust, independent oversight is needed.
Studies by the Department of Homeland Security (DHS) and the National Institute of Standards and Technology (NIST) have also raised concerns about demographic bias in facial recognition systems. Although top-performing algorithms exhibit high accuracy overall, disparities remain: systems tend to perform better for lighter skin tones, men, and older individuals. CBP claims its deployed systems have minimized these discrepancies, but external audits are limited.
Despite these concerns, airports like SJC and Eppley are moving forward with full-scale biometric integration. CBP officials cite both security benefits and operational efficiencies, noting that facial biometrics have helped intercept impostors and reduce average wait times. As adoption expands, the debate over traveler privacy, data protection, and algorithmic fairness is likely to intensify, prompting renewed calls for stronger policy frameworks around biometric surveillance technologies.
