Biometric solutions: Facial recognition, fingerprinting, and retina scans
Biometric solutions are increasingly being used as authentication methods in airports. These include facial recognition, fingerprinting, and retina scans, which offer enhanced security and a more seamless travel experience for passengers.
Facial recognition technology has been introduced at select airports, allowing travellers to voluntarily use their faces to verify their identity during screening. This technology compares a live image of the traveller to the image on their physical identification or passport, ensuring the person matches their documentation. The Transportation Security Administration (TSA) in the United States, for example, uses Credential Authentication Technology 2 (CAT-2) scanners to automate the manual ID verification process. This technology is currently deployed at nearly 250 airports nationwide, with plans to further evaluate its performance. It is worth noting that privacy is a key consideration, and photos are generally not stored or saved after a positive ID match.
Fingerprinting is another biometric solution that can be used for airport authentication. While it is not as commonly used as facial recognition or iris scanning, it is still a valid option. Fingerprinting involves scanning a person's unique fingerprint pattern for identification.
Retina scans, or iris recognition, is a biometric technology that has proven to provide fast and accurate identity authentication results. The iris, the coloured ring around the pupil, has 240 unique recognition points, far more than fingerprints or facial recognition technologies. This makes it extremely accurate, even for identical twins or family members. Iris recognition technology is used in several international airports, such as Hamad International Airport in Doha, Qatar, and Amsterdam Schiphol Airport's Privium program. Travellers can enrol their digital iris templates, which are stored on a secure card. To pass through a security gate, they insert their card and scan their iris, with the gate opening if there is a match. This process can clear immigration and customs in under 15 seconds, significantly reducing wait times.
Biometric technologies offer a range of benefits, including enhanced security, accuracy, and speed. They provide a more modern approach to authentication, reducing physical contact and streamlining the airport experience for travellers.

Credential Authentication Technology (CAT): Advanced ID verification systems
Credential Authentication Technology (CAT) is an advanced ID verification system that enhances security screening and enables a touchless experience. It is a security game-changer, ensuring ID authentication, reservation verification, and Secure Flight pre-screening status are known in near real-time at airport security checkpoints. When a CAT unit is in operation, a TSA officer will ask travellers for their photo IDs. The officer will then insert the ID into the CAT unit, which will scan and analyse it. CAT is electronically linked to the Secure Flight database, which confirms travellers' flight details. It also displays the pre-screening status the traveller is eligible for, all without a boarding pass.
The next generation of CAT, CAT 2, enhances security screening and enables a touchless experience through biometric technology. This includes facial matching and the acceptance of digital identity credentials, such as Mobile ID. CAT 2 units are equipped with readers that allow travellers to use state-issued digital driver's licenses or digital identification cards for TSA identity verification purposes. Travellers who do not wish to participate in the facial matching process can opt out in favour of an alternative identity verification process.
CAT improves the travel document checker's ability to accurately authenticate passenger identification and pre-screening status, addressing the vulnerabilities associated with ID and boarding pass fraud. It provides enhanced fraudulent ID detection capabilities while confirming the identity and flight information of travellers.
The TSA continues to integrate new technologies into its identity verification process. TSA is evaluating biometric solutions to enhance security, efficiency, and the passenger experience. Facial matching, digital identity, and facial identification technologies can play an important role in enhancing the TSA checkpoint by automating current manual ID verification procedures.

Manual ID verification: Checking physical documents such as passports or driver's licenses
While the Transportation Security Administration (TSA) is increasingly exploring and adopting digital and biometric authentication technologies, the manual ID verification process remains important. This typically involves a TSA officer visually inspecting a passenger's physical identity documents, such as a passport or driver's license.
Passengers are encouraged to carry acceptable forms of physical identification when travelling. In the U.S., these typically include REAL ID-compliant driver's licenses, state-issued photo identity cards, passports, passport cards, and certain trusted traveler cards. It is important to note that the list of acceptable IDs can change, and passengers are advised to check before travelling.
During manual ID verification, a TSA officer will visually inspect the physical document presented by the passenger. They will typically collect information such as the passenger's name, current address, and other personal details to confirm their identity. This process may also involve additional screening measures, such as a pat-down or screening of carry-on property.
In some cases, passengers may not have their physical ID with them or may have lost or misplaced it. In such situations, TSA officers have some flexibility and may accept alternative forms of identification. These can include credit cards, checkbooks, membership cards with photos, or even answering security questions over the phone. While these alternatives are not guaranteed to work, they may be considered in exceptional cases.
While manual ID verification is still a common practice, the TSA is actively exploring biometric solutions, such as facial matching, digital identity, and facial identification technologies. These technologies aim to enhance security, efficiency, and the overall passenger experience by automating manual ID verification procedures. Passengers can also opt for digital IDs, which offer enhanced security and privacy compared to physical credentials.

Digital IDs: Mobile driver's licenses and mobile identification cards
Digital IDs are electronic representations of personally identifying information (PII) that can be used to verify a person's identity. Mobile driver's licenses and mobile identification cards are types of digital IDs issued by a state. They are digital representations of the information contained on a physical driver's license or ID card issued by the state and stored on a mobile device such as a smartphone. Mobile driver's licenses require biometric verification before each transaction.
Mobile driver's licenses and mobile identification cards offer several advantages over traditional physical IDs. Firstly, they provide enhanced security. Digital IDs are more secure than physical credentials, which are susceptible to counterfeiting and fraud. Digital IDs also offer increased privacy as individuals only share the information necessary for identity verification, protecting their personal data. Additionally, the use of mobile driver's licenses and mobile identification cards can modernize checkpoint screening procedures, streamline technologies, and reduce contact points for passengers, ultimately improving the overall travel experience.
To use a mobile driver's license or mobile identification card at an airport, individuals must first ensure they have a TSA-approved digital ID app or a digital wallet on their mobile device. They can then add their eligible state-issued driver's license or identification card to their phone by following the setup instructions provided by the app or wallet. At TSA checkpoints, individuals can scan their Digital ID QR code or tap their mobile device on the digital ID reader. It is worth noting that the use of mobile driver's licenses and mobile identification cards for airport authentication is currently available at select airports and may vary by terminal and checkpoint.
While the use of mobile driver's licenses and mobile identification cards offers enhanced security and convenience, it is still recommended to carry a physical credential as a backup option. This is because the availability of digital ID infrastructure and acceptance may vary across airports and terminals. Additionally, individuals should always check the latest acceptable forms of identification before traveling to ensure they have the necessary documentation for seamless airport authentication.

Alternative forms: Credit cards, checkbooks, or membership cards with photos
While passports and driver's licenses are the most common forms of identification used at airports, there are several alternative forms of ID that can be used in case of an emergency. Credit cards, checkbooks, and membership cards with photos can be used as alternative forms of identification. These alternative forms of ID are not guaranteed to work, but they are worth trying when other options are not available.
Credit cards can be used as a form of authentication as they contain key personal information, such as the cardholder's name and signature. Additionally, credit card companies perform background checks before issuing cards, which adds to their credibility as a form of identification.
Checkbooks also contain important personal information, including the account holder's name, address, and sometimes a photo or signature. As with credit cards, issuing banks conduct thorough background checks before opening accounts, making checkbooks a reasonably trustworthy form of ID.
Membership cards with photos can also serve as alternative identification. Examples include Costco membership cards, which feature a black-and-white photo of the cardholder, and Clear membership, which offers expedited airport security with biometric authentication, including fingerprint or eye scans.
It is important to note that while these alternative forms of identification may be accepted in certain situations, they are not universally recognised. The acceptance of these IDs may vary depending on the airport, the country, and the discretion of the TSA officer conducting the security check.
To enhance security and improve traveller convenience, the Transportation Security Administration (TSA) in the United States is exploring the use of biometric solutions and facial comparison technology at select airports. This technology automates the manual ID verification process by comparing a traveller's live photo with the image on their photo ID, such as a passport or driver's license. However, participation in facial comparison technology is voluntary, and travellers can opt for standard ID verification if they prefer.
