Is AI the Catalyst to Passport-Free Travel? TSA Showcases Biometric and AI Airport Security
Las Vegas, NV – January 23, 2025 – The rumble of policy changes following the commencement of Donald Trump’s second term, particularly concerning immigration, sets a stark backdrop for the Transportation Security Administration’s (TSA) unveiling of its latest technological arsenal at CES 2025. With increased national focus on border control and security imperatives, the TSA’s innovations are not merely incremental upgrades; they represent a significant leap towards a future where air travel is both more secure and seamlessly efficient.
As over 140,000 attendees converged on Las Vegas via Harry Reid International Airport for CES 2025, the TSA strategically chose this global platform to showcase technology designed to address the evolving challenges at the intersection of immigration and security. From biometric authentication to artificial intelligence and virtual reality, the agency’s display presented a compelling vision for the future of airport security and passenger processing.
Biometric Authentication and Credential Verification: Your Face as Your Boarding Pass
At the forefront of TSA’s technological showcase was the Credential Authentication Technology (CAT) machine. This system embodies the growing movement towards biometric solutions, employing facial recognition to confirm passenger identities. Lucy Rimensnyder, a TSA program manager, elucidated that this “one-to-one match” technology directly compares a live facial scan against the photo embedded in the passenger’s physical ID, such as a passport or driver’s license. This process is pivotal in ensuring that the individual presenting the document is indeed its legitimate owner, effectively thwarting potential identity fraud at travel document checkpoints.

“We’re continuously seeking innovative technologies to elevate the passenger experience while maintaining the highest security standards,” Rimensnyder stated. This pursuit aligns with industry trends, as highlighted by SITA data, which projects that around 70% of airlines globally will implement biometric identification by 2026. Furthermore, a Statista survey indicated that 46% of global passengers used biometrics at airports in 2023, underscoring the rapid acceptance and deployment of these technologies.
The TSA is also actively collaborating with airlines to introduce touchless identity solutions, currently available on an opt-in basis for pre-check passengers. These systems promise to clear passengers in a mere two to three seconds, significantly reducing queues and enhancing airport flow. Looking ahead, Rimensnyder envisions a future where physical travel documents may become obsolete. “Personally, I believe we are heading towards a passportless journey,” she speculated, acknowledging the concurrent need to address privacy concerns and ensure opt-out options remain available. Matt Gilkeson, TSA’s CTO, echoed this sentiment, noting the increasing comfort levels with biometrics and the strong industry interest in seamless travel experiences, particularly among European airlines who see biometrics as a tool for passenger facilitation as much as for enhanced security.
AI and Machine Learning: Smarter, Safer Screening
Artificial intelligence is not just a buzzword at TSA; it’s a critical component of their evolving security framework. Gilkeson pointed out that machine learning algorithms, implemented just two years prior, have already achieved a remarkable 50% reduction in the need for physical pat-downs during passenger screenings. “This not only accelerates the screening process but also significantly improves passenger comfort by minimizing physical contact,” Gilkeson explained. He emphasized the dual benefit: faster processing and a more dignified experience for travelers.
Moreover, AI algorithms have introduced a valuable element of neutrality to security screenings. By removing the necessity to assign officers based on gender alignment with the traveler, the process becomes more streamlined and less intrusive. Agents can now operate screening technology with a single, gender-neutral process.
Beyond screening, the TSA is exploring generative AI for incident response. Gilkeson detailed how this technology could revolutionize how officers handle security incidents, from documenting events to escalating them to law enforcement and ensuring adherence to procedural protocols. “In situations involving prohibited items or security breaches, precise documentation and procedural accuracy are paramount,” he stated. “Agentic AI could provide real-time assistance in managing complex scenarios, ensuring rapid and efficient escalation to the appropriate authorities.”
However, Gilkeson stressed the importance of responsible AI implementation, particularly rigorous data testing to anticipate and mitigate potential performance anomalies. “Thorough testing and data quality are critical. We must understand the datasets driving our AI, monitor for data drift, and address any unexpected performance issues proactively,” he cautioned. He underscored the necessity for well-defined operational boundaries for AI systems to maintain both security integrity and system reliability.
Emerging Technologies: Peering into the Future of Security
The TSA’s showcase at CES 2025 extended beyond current deployments to preview groundbreaking prototype technologies, including a shoe scanner utilizing millimetre-wave technology. This device is designed to scan footwear for concealed items without requiring passengers to remove their shoes. Passersby at the TSA booth even contributed to the technology’s development by testing the scanner, helping to broaden its data collection.

Brian Lewis, a Department of Homeland Security contractor, highlighted the importance of gathering diverse data to refine the scanner’s accuracy, including accounting for RFID tags commonly found in certain shoe brands for inventory tracking. “Our aim is to streamline screening without causing unnecessary delays,” Lewis explained. While still in the prototype phase, plans are underway to deploy test units at airports in the coming years. Lewis also sees potential beyond airports, envisioning applications in mass transit hubs and large venues like stadiums, aiming to facilitate rapid and secure entry for large numbers of people.
Quang Vo, a TSA developer, introduced another futuristic tool: a virtual reality (VR) headset for baggage inspection. This system leverages CT scan data and open-source medical imaging architecture, enabling officers to conduct virtual inspections of flagged baggage items. This approach minimizes physical handling and enhances officer safety while generating more precise data for machine learning enhancement in threat detection. “By virtually labelling objects within VR, we can significantly improve the accuracy of our automated threat detection algorithms,” Vo explained. Although VR hardware limitations currently preclude large-scale deployment, Vo indicated substantial progress towards overcoming these hurdles.

Navigating Challenges: Scaling, Privacy, and Public Trust
Despite the promise of these technological advancements, the TSA acknowledges significant challenges in scaling and widespread implementation. Rimensnyder noted that funding and time constraints often impede rapid deployment, prompting the TSA to explore alternative strategies such as public-private partnerships and collaborations with national laboratories. “We are actively seeking innovative pathways to expedite the deployment of these technologies into operational checkpoint environments,” Rimensnyder stated. This includes engaging with companies at earlier stages of technology development, offering testing and development support to accelerate readiness for TSA requirements.
Privacy remains a central concern in the adoption of biometric and AI technologies. Gilkeson emphasized TSA’s commitment to transparency and rigorous privacy protection. He highlighted that comprehensive privacy impact assessments are conducted for every system deployed. “We are highly conscious of data privacy. We only collect necessary data, and it is deleted as soon as it is no longer needed,” he assured. Gilkeson also contrasted government protocols with commercial practices, noting the government’s mandated transparency through privacy impact assessments, a requirement often absent in commercial biometric applications. He pointed out the apparent paradox of public willingness to share data with commercial entities while questioning government data collection, despite the government’s structured privacy safeguards.
According to TSA guidelines on biometric technology, passengers participating in biometric tests are always informed and retain the option to choose standard ID verification methods instead, ensuring passenger choice and control over their data.
