A major airport in the United States has begun rolling out a new touchless security checkpoint that allows eligible travelers to glide through Transportation Security Administration screening without presenting a physical passport or boarding pass, using facial biometrics tied to what some officials and commentators are calling a “DNA passport” style of digital identity.

The system, part of TSA’s expanding PreCheck Touchless ID program, is being introduced at Boston Logan International Airport with promises of shorter lines, less fumbling for documents, and a glimpse of how biometrics and genetic identifiers may shape the future of border and airport security.

Boston Logan Becomes Latest Testbed for Touchless TSA Screening

Boston Logan International Airport in Massachusetts has confirmed that select security lanes are now equipped with TSA PreCheck Touchless ID, an upgraded checkpoint experience that replaces manual document checks with an automated facial comparison. Instead of handing over a passport or driver’s license, enrolled travelers pause briefly at a pedestal-like scanner, look into a camera, and wait a moment while the system cross-checks their image against passport data already on file.

The technology is designed to verify that the person standing at the checkpoint is the same individual associated with the reservation and the government-issued identity document stored in secure databases. Once the match is made, the lane opens and the traveler proceeds directly to the familiar bag and body screening machines. TSA officers still oversee the process, but their role shifts from physically handling IDs to monitoring the system and responding to any mismatches or alerts.

For now, the touchless option at Logan is limited to specific terminals and participating airlines and is only available to TSA PreCheck members who have opted in. Eligible travelers will see a “Touchless ID” indicator on their mobile boarding pass, signaling that their biometric profile is active for that journey. Even with the new system in place, TSA is advising passengers to continue carrying their physical IDs since officers can still request traditional documents if something flags in the system.

How the ‘DNA Passport’ Concept Fits Into Airport Security

The phrase “DNA passport” is not an official TSA term but reflects a broader shift toward identity systems rooted in unique biological markers rather than plastic cards or paper booklets. What is rolling out at Boston is facial recognition based on a traveler’s government-issued photo, not DNA sampling at the checkpoint. Yet it is emerging alongside a separate legal and policy push that explicitly authorizes U.S. agencies to collect highly sensitive biometric data, including DNA, from certain travelers at ports of entry and exit.

Under rules that took effect across U.S. airports in late 2025, Department of Homeland Security officials can request facial images, fingerprints, and in some cases DNA from non-citizens entering or leaving the country. Those samples are intended for law enforcement and immigration enforcement purposes, rather than day-of-travel identity verification. Still, privacy advocates note that the coexistence of facial recognition lanes at security checkpoints and expanded DNA collection powers at borders is moving the United States closer to a continuum of biometric tracking that begins well before a traveler arrives at their boarding gate.

In practice, the touchless checkpoint at Logan acts less like a genetic passport and more like a biometric key that unlocks the digital version of your traditional passport stored in government systems. The traveler’s face is the token, and the back-end match confirms that the person in front of the camera is linked to a known, vetted identity. But the “DNA passport” label captures a growing public sense that the next phase of travel may be defined by who we are biologically rather than what we carry in our wallets.

What Passengers Need to Do to Use Touchless ID

To take advantage of the new technology at Logan and other airports, travelers must first be TSA PreCheck members, which requires a background check, an enrollment process, and a Known Traveler Number. On top of that, they have to opt in to Touchless ID with their airline, usually via the airline’s app or frequent flyer profile, by uploading or confirming passport details and agreeing to the use of biometrics for airport identity checks.

Once enrolled, the system links three elements: the traveler’s TSA PreCheck status, their passport information, and their airline reservation. When they check in for a flight on a participating carrier, the airline’s system flags that the traveler has opted in, and a special Touchless ID symbol appears on their mobile boarding pass. That symbol tells TSA systems at the airport that the traveler’s facial template can be used at the checkpoint instead of an ID document.

At the airport, the actual touchless process is simple but tightly choreographed. In the PreCheck line, travelers walk up to the scanner, align their face with the on-screen guide, and hold still while a camera captures a live image. Advanced software compares this image with the reference photo stored in government databases, usually drawn from the traveler’s passport. If the images match within an acceptable confidence range and the name on the reservation lines up with what is on record, the gate opens and the traveler proceeds forward. If there is no match or the system encounters an error, the traveler is pulled aside for a conventional ID check with an officer.

TSA’s Nationwide Push to Expand Touchless Checkpoints

Boston Logan’s rollout fits into a larger national strategy to bring Touchless ID to dozens more airports in 2026. TSA has already launched the program at major hubs such as Hartsfield Jackson Atlanta International Airport and John F. Kennedy International Airport in New York. Agency statements in recent weeks have outlined plans to extend the technology to roughly 50 additional airports by late spring, bringing the total to around 65 locations across the country.

Priority additions include anchor airports such as Anchorage, Baltimore, Boston, Dallas Love Field, Fort Lauderdale, Houston’s Bush Intercontinental and Hobby, John Wayne Airport in Orange County, Kansas City, Long Beach, Miami, Orlando, West Palm Beach, San Jose, Sacramento, and Washington Dulles. After that first wave, TSA expects the systems to arrive at a broader mix of mid-size and regional airports, from Albuquerque and Austin to Tampa, Tulsa, and Westchester County in New York.

The expansion builds on earlier biometric pilots that started with document-check kiosks where travelers inserted their license or passport and then looked into a camera so the system could compare the ID photo with a live image. In cooperation with airlines and airport operators, TSA has been gradually moving that same matching capability into the heart of the PreCheck experience, removing the need to present any document at all as long as the digital identity checks out.

Airlines Race to Integrate With TSA’s Touchless Future

Airlines are playing a central role in making Touchless ID workable at scale because they control the customer relationship and the reservation systems that flag who is eligible. Major carriers including Delta Air Lines, American Airlines, Southwest Airlines, United Airlines, and Alaska Airlines have either launched or announced integrations that allow their loyalty program members with TSA PreCheck to enroll in the biometric option.

Delta was an early mover, building a “digital identity” experience that lets customers check bags and pass through security using only their face at hubs like Atlanta, Detroit, Los Angeles, LaGuardia, JFK, Salt Lake City, Washington National, and Seattle. American has been working with TSA to invite AAdvantage members to opt in for a streamlined PreCheck experience using facial comparison in select airports. Southwest has been accelerating its own rollout after a pilot in Denver, with additional touchless checkpoints now operating at airports in Atlanta, New York LaGuardia, Portland, Seattle, and Salt Lake City.

These integrations are technically complex, requiring airlines to synchronize passport data, PreCheck status, and flight details with TSA’s systems in near real time while complying with privacy regulations. Some travelers have reported glitches, such as Touchless ID icons appearing on their boarding passes but failing to work at the checkpoint, or disappearing entirely despite previous successful use. Industry analysts expect such issues to diminish as the programs move from pilot to full production and data pipelines are refined.

The rapid spread of facial recognition and related biometrics at U.S. airports has raised questions far beyond the length of the security line. Civil liberties groups have warned that normalizing face scans and, in some contexts, DNA collection in travel settings could lead to routine surveillance that extends well beyond security needs. They also argue that travelers may feel they have little practical choice but to consent if refusing a biometric scan means longer waits or additional scrutiny.

TSA and its partners counter that the PreCheck Touchless ID program is strictly opt in and that images captured at the checkpoint are either not retained or are stored with limited lifespans and access controls. Airlines emphasize that they use encrypted channels to exchange data and that facial images are matched against passport photos already held by the government, not against open-ended databases. Clear, the private biometric company that is deploying eGates in partnership with TSA at airports such as Atlanta, stresses that it does not have access to watchlists and cannot override TSA’s security decisions.

Even with these safeguards, experts say continued oversight will be critical. Questions remain about how long biometric data is kept, how it might be shared with other agencies, whether it can be used in investigations unrelated to travel, and what recourse travelers have if their data is misused or if the systems generate false positives or false negatives. For non-citizens, the stakes are particularly high, as biometric mismatches at the border can trigger immigration consequences or lengthy detentions.

Will Touchless ID Really Slash Wait Times?

For travelers, the most immediate promise of the touchless checkpoint is faster movement through security. By automating ID checks that used to require a manual document review by an officer, TSA believes it can process more people per lane per hour and reduce bottlenecks at the front of the screening area. The technology also aims to reduce lines within the PreCheck program itself, which has grown significantly since its launch as more frequent travelers pay for a quicker, more predictable security experience.

Operationally, the benefits may vary by airport and time of day. In some locations, the main choke point is the ID podium, where a single officer can only inspect so many documents at once. Replacing that human gatekeeper with an automated biometric system that can scan faces in rapid succession could meaningfully speed the flow. In other airports, baggage and body scanners are the real constraint, and travelers may find that they pass through the touchless gate only to join the same familiar queue for the X-ray belt and advanced imaging machines.

Industry observers say real-world measurements of wait times before and after the deployment of touchless checkpoints will be key to validating TSA’s claims. So far, anecdotal reports from early adopters at hubs like Atlanta and Los Angeles suggest that when everything works correctly, the experience can reduce friction and make the process feel more seamless. However, travelers encountering misreads or system outages can end up spending more time at the checkpoint than they would have with a traditional ID check, especially if staff are still learning how to troubleshoot the new equipment.

What This Means for the Future of Travel

The Boston rollout signals that biometric-first identity verification is moving from experiment to expectation in U.S. air travel. As more airports adopt Touchless ID and related systems such as eGates, the idea of walking through an entire departure journey without ever showing a passport or boarding pass may become routine for frequent flyers. Instead, their face, fingerprints, and potentially DNA markers collected at earlier stages of their travel histories will anchor a persistent digital identity that airlines and security agencies can call up on demand.

For travelers, the tradeoff will be measured in seconds saved at security versus the comfort level of handing over ever more intimate personal data in exchange. For airports and airlines, the calculus centers on operational efficiency, customer satisfaction scores, and the competitive appeal of marketing a “frictionless” curb-to-gate experience. For regulators and lawmakers, the challenge will be to ensure that as biometric and genetic technologies evolve, the privacy protections and civil liberties frameworks surrounding them keep pace.

In the near term, passengers passing through Boston Logan and other leading hubs will be among the first to test what this new model of “touchless” travel feels like in practice. As they look into cameras instead of pulling out passports, the rest of the industry will be watching to see whether this latest evolution of the TSA checkpoint truly delivers on its promise to cut wait times while keeping both security and public trust intact.
