The global aviation industry is accelerating the transition to contactless travel
The aviation industry is entering a new phase of digital transformation in which biometrics and digital identity are gradually moving beyond limited tests and into real operational use. The latest trials and regulatory developments indicate that contactless travel technology is technically mature, but also that its wider rollout will depend on something just as important as cameras, readers, and mobile wallets: common rules, mutual recognition of credentials, and passenger trust. That is precisely why, in recent months, the central issue in the debate is no longer whether such a system can work, but how to connect it between airlines, airports, border services, and state systems so that the passenger no longer has to prove the same identity multiple times at every step of the journey.
In this process, the International Air Transport Association, or IATA, and the International Civil Aviation Organization, ICAO, play a key role. Their standards and recommendations should ensure that digital identity and biometric verification do not remain limited to individual technological demonstrations, but become part of a broader and harmonized system that will apply across different markets. The latest industry demonstration, conducted on the Hong Kong – Tokyo route, showed that a passenger can use different digital wallets and travel credentials, while the system still successfully recognizes identity and enables passage through key points at the airport. This is an important signal to the industry, because interoperability is precisely what makes the greatest difference between an attractive pilot project and a model that can be replicated globally.
From physical documents to digital credentials
The idea of contactless travel is not limited to a passenger showing their face instead of a passport. Behind it lies a far more complex concept of digital identity, in which data from a travel document and other relevant documents can be securely verified in advance and then used to confirm identity in real time. In its guidelines, ICAO describes the digital travel credential as a secure and globally interoperable digital companion, and potentially also a replacement for a physical electronically readable travel document. Such an approach should make it possible for part of the checks to be carried out before the passenger arrives at the airport, opening the way for faster passage, fewer delays, and less reliance on manual document checks.
For air transport, this is particularly important because different layers of identification often overlap within a single journey. The passenger checks in with the carrier, drops off baggage, passes through security screening, enters the lounge, goes to the boarding gate and, depending on the route, passes border control multiple times. In the traditional model, this means repeatedly showing a passport, boarding pass, or visa. In the contactless travel model, the same passenger can share verified digital attributes in advance and then confirm them during the journey itself through biometrics. This not only speeds up passenger flow, but also reduces the possibility of errors, especially at moments when airports are operating under the heaviest load.
Hong Kong and Tokyo as proof that interoperability is no longer theory
One of the most important events for this topic was IATA’s announcement that the industry is ready for a fully digital travel experience after a trial in which two passengers, using different digital wallets and credentials, completed a round trip between Hong Kong and Tokyo. This was not a laboratory experiment detached from real traffic, but a demonstration in a live environment, with the participation of the airline Cathay Pacific, the airports in Hong Kong and Narita, and several technology partners. In that demonstration, seven verifiable credentials were used, including a copy of the e-passport, a live biometric image, a visa, reservation data, and a boarding pass.
The importance of that trial goes beyond the route itself between two Asian hubs. It showed that different digital wallets can function within the same process, with a trust registry that confirms the issuers of the data. This is exactly what the industry has been seeking for years: a system in which the passenger is not tied to one application, one supplier, or one airport. If digital identity is to be introduced globally, it must work under real conditions, among different stakeholders, and in an environment where there is no single operator of the entire journey. IATA is therefore stating ever more openly that the next step is moving from proof of concept to broader pilots and operational implementation.
Asia leads in practical implementation
Asian markets are already showing why they are often cited as leaders in contactless travel. Singapore’s Changi, one of the busiest and most technologically advanced airports in the world, states that all passengers, including first-time visitors, can use automated immigration clearance on arrival and departure without prior registration, provided they have a valid passport compliant with ICAO standards. In addition, the Singaporean authorities and the airport itself have already publicly communicated that passengers on departure can also use “passport-less” processing models, which shows how identity checks are gradually shifting from the physical document to digital and biometric confirmation.
Why this example is important for the rest of the world can be seen in two dimensions. First, it is a system that is not applied only to citizens or previously registered users, but to a very broad range of passengers, including foreign visitors. Second, Changi shows that automation is no longer just an additional service to speed up passage, but a core part of the passenger process. When such a model takes hold at a major international hub, pressure grows on other airports and carriers to adapt their own systems so that travel between different markets remains connected and simple.
Europe is introducing biometrics through border systems and airport adaptation
In Europe, the development of contactless travel is strongly linked to public policies and border systems. The most important step is the Entry/Exit System, or EES, the new European system for registering the entries and exits of third-country nationals traveling for a short stay. The European Commission states that the system began operating on 12 October 2025, with gradual rollout across 29 European countries, and that from 10 April 2026 it becomes fully operational. The EES replaces manual passport stamping with a digital record of entries, exits, and refusals of entry, while also recording biometric data such as fingerprints and a captured facial image.
Although the EES is not the same as the commercial “seamless travel” being developed by carriers and airports, it is a crucial infrastructural step. Without digitally processed identity checks at the border, it is difficult to imagine a fully contactless international passenger flow. The European Commission emphasizes that the system is designed with respect for fundamental rights and data protection, which is especially important in the European regulatory framework. In other words, Europe is moving toward contactless travel more cautiously than some Asian markets, but that approach comes with clear rules on the processing of identity and biometric data, which could in the long term prove crucial for public trust.
Some European airports have already adapted their operational processes to the new rules. Amsterdam Schiphol publicly states that, for the purposes of the EES, self-service kiosks are being introduced where passengers can register, after which the Royal Netherlands Marechaussee completes the check. Schiphol also points out that registration includes passport scanning, facial recognition, and fingerprint collection, and that the border procedure is therefore being reorganized so that passenger flow remains smooth. This shows that in Europe the technology is being introduced not only as a promise of a future experience, but also as a very concrete adaptation of infrastructure, space, and working processes on the ground.
What this concretely changes for passengers
For passengers, the most visible change is that identity will no longer be proven exclusively by handing over a physical document from hand to hand. In the model advocated by IATA and its partners, the passenger could send part of the data in advance via credentials stored in a digital wallet, while at the airport they would pass through key points by confirming their face or another biometric characteristic. This can include baggage drop, security access, lounge entry, and boarding. In its materials, IATA emphasizes that such an approach can reduce the number of touchpoints, speed up passenger flow, and relieve staff of part of the manual checks.
In practice, however, this does not mean that the passport will disappear overnight from every passenger’s pocket. During the transition period, physical documents will remain an important safety and legal backup, especially in markets where standards are not yet aligned or where national regulations require traditional verification. For that reason, the coming years will very likely be marked by a hybrid model: part of the process will be digital and biometric, and part will still require a physical travel document. It is precisely in this transitional phase that it will become most evident how operationally feasible interoperability and standardization truly are, and not merely desirable in principle.
Standards are becoming more important than the technology itself
One of the reasons why this topic has now returned to the center of the industry debate is the fact that the basic technology is already largely available. Facial recognition cameras, chipped passports, secure mobile wallets, and verifiable credentials are no longer experimental products. The main challenge is to agree on how data will be issued, how it will be verified, who will trust which issuer, and in what way it will be ensured that the passenger has a comparable experience in different markets. ICAO therefore views digital travel credentials primarily as a standardization project in global aviation, and not merely as a technological innovation.
In the meantime, IATA has developed recommended practices through the One ID framework. In June 2024, a recommended practice for contactless travel was published, and in the 2025 fact sheet, IATA states that the goal is to enable passengers to use biometric recognition for identity verification during the process, with full respect for privacy and personal data protection. That wording is not accidental. If the industry wants broad acceptance, it will not be enough simply to claim that travel is faster. It will have to prove that it is also safer, more transparent, and that the passenger knows where their data is used, how long it is kept, and who can access it.
Privacy, trust, and the legal framework remain key issues
For many passengers, biometrics in travel sounds practical, but at the same time it raises questions of privacy and the possibility of error. In the European context, it is especially important who manages the databases, under what rules sensitive information is accessed, and how secondary use of the data beyond the original purpose is prevented. In its description of the EES, the European Commission points out that the system is implemented with respect for fundamental rights and data protection, and that eu-LISA, the agency responsible for large-scale information systems in the area of freedom, security, and justice, is responsible for the system’s development and management. Yet the regulatory architecture alone will not be enough if passengers are not given clear and understandable explanations of what exactly is being collected and why.
On the other hand, the aviation industry claims that a well-designed system could also reduce some existing risks. If credentials are verified in advance and identity is confirmed on the basis of data coming from trusted sources, the room for document forgery, identity fraud, and errors in manual checks is reduced. Another advantage is that different points of the journey can be connected into one logical chain of verification, instead of each institution requesting the same proof again. Still, acceptance of such a model will depend on whether the rules of oversight, auditing, and legal responsibility are as robust as the technology itself.
Operational benefits for airports and carriers
For airport operators and airlines, digital identity is not only a matter of user experience, but also of capacity. A larger number of passengers with the same spatial and staffing resources is one of the industry’s biggest challenges, especially after the recovery of international traffic. If part of the checks is automated, airports can process passengers more quickly without constantly expanding physical infrastructure. This is especially important at hubs where space is limited and peak-hour congestion has a direct effect on delays, connections, and passenger satisfaction.
In its materials, IATA emphasizes that One ID and the contactless model can reduce the number of repetitive processes, increase productivity, and enable passengers to arrive at the airport “ready to fly” in a greater number of scenarios than today. For carriers, this also means less time spent checking documentation at counters, and potentially fewer operational delays at boarding gates. But the real benefit will depend on how successfully airports, carriers, and government services manage to connect their systems without creating new bottlenecks. If the passenger still has to stop multiple times because of exception checks, incompatible databases, or additional questions, then the promise of contactless travel easily turns into just another layer of complexity.
Why the global rollout will not be equally fast everywhere
Despite visible progress, there is no indication that the whole world will move to fully contactless travel at the same speed. Differences among countries in legal frameworks, digital infrastructure, levels of investment, and political readiness will remain large. Some markets will advance through commercial pilots by airports and carriers, while others will prioritize border and security systems. In Europe, a large part of the change is currently taking place through a public regulatory framework such as the EES. In Asia, operational and user aspects are in some cases more visible, with faster acceptance of automated gates and paperless processes.
That does not mean that there is one “correct” model. It is more likely that the global system will be built gradually, through linking different national and commercial solutions that will have to rely on common standards. That is precisely why ICAO’s guidelines on digital travel credentials and IATA’s recommended practices are so important. They create a common language among states, border services, airlines, technology companies, and airport operators. Without that, each market could develop its own closed system, and passengers would receive new fragmentation instead of simpler travel.
What follows after 8 April 2026
On the date of 08 April 2026, there is no longer any serious doubt that the direction of development of the aviation industry is clearly set. The technology for contactless travel exists, standards are taking shape, and concrete implementations are already visible in key markets. Europe is simultaneously completing the full transition to the EES, while Asian hubs such as Hong Kong, Tokyo, and Singapore show how operational models can function in practice. The next major stage will be the expansion of interoperable solutions to a larger number of routes, carriers, and border points, with careful alignment of regulatory and technical requirements.
For passengers, this means that the travel experience in the coming years will very likely begin to change not through one dramatic cut, but through a series of seemingly small changes: fewer stops for checks, more automated passages, earlier digital data verification, and a gradual reduction in dependence on paper or manually inspected documents. For the industry, however, this is a far greater shift. If it succeeds in connecting biometrics, digital identity, and international standards without undermining privacy and legal certainty, aviation could for the first time after a long series of years gain a truly global travel model in which identity is verified once and recognized throughout the entire journey.
