The Cross Border Xpress (CBX) pedestrian bridge connecting San Diego with Tijuana International Airport has deployed facial recognition systems, integrating U.S. Customs and Border Protection’s (CBP) biometric screening processes into its operations. The installation makes CBX the latest U.S.–Mexico land border facility to adopt facial biometrics as part of ongoing efforts to streamline traveler processing and improve security at ports of entry.
While CBX’s implementation marks a notable milestone for this privately operated border crossing, facial recognition technology has been in use at U.S.–Mexico land ports since at least January 2021. CBP initially introduced its Simplified Arrival biometric program at crossings such as San Ysidro and Otay Mesa pedestrian lanes, and by May 2025, facial recognition systems had been deployed in all pedestrian lanes at both the Southwest and Northern Borders, enhancing the agency’s capacity to match traveler identities to official documents quickly and accurately.
Facial Recognition Integrated into CBX Terminal
The new system at CBX captures images of travelers as they pass through designated lanes, comparing facial features to the photographs embedded in passports or other travel documents. This automation reduces the need for manual document checks while maintaining security protocols. The move reflects broader trends in biometric adoption across U.S. entry points, following recent deployments at Minneapolis-St. Paul International Airport and JFK’s Terminal 8.
CBX has used facial analytics previously for operational purposes. In 2020, RealNetworks’ SAFR facial recognition technology was deployed within the terminal to monitor passenger flow and reduce congestion. The latest deployment integrates CBP’s enforcement-grade facial comparison tools, enhancing security screening alongside the existing infrastructure.
Privacy Safeguards and Civil-Liberties Concerns
U.S. Customs and Border Protection states that privacy protections are built into its biometric systems. For U.S. citizens, facial photographs captured during entry are deleted within 12 hours, while images of non-U.S. citizens may be retained for longer under federal regulations. However, details about how biometric data is handled on the Mexican side of the CBX crossing remain unclear, and no joint data-sharing policies between CBP and Mexico’s National Migration Institute (INM) have been publicly disclosed.
Privacy advocates, including organizations like the American Civil Liberties Union (ACLU), have raised ongoing concerns about the expansion of facial recognition at land borders, citing risks of surveillance overreach, potential inaccuracies affecting certain demographic groups, and a lack of transparency around data retention practices. Legislative developments, such as proposals under the draft U.S. Privacy Act Modernization, may eventually reshape how biometric data is collected and stored at border crossings like CBX.
As the CBX installation becomes fully operational, it may serve as a model for similar deployments at other high-traffic crossings. The continued integration of facial recognition technology reflects CBP’s long-term vision of improving efficiency and security at U.S. borders, while balancing the complex challenges of privacy protection and civil liberties.
