In the face of growing traveller volumes, complex global supply chains and increasing geopolitical risk, airports and seaports are under renewed pressure to streamline security while maintaining the highest levels of control.

A new wave of innovation has emerged across the globe, aimed at modernising customs and security operations through artificial intelligence, biometric technology, and remote screening. From Changi Airport to the Port of Rotterdam and U.S. entry points, these developments aim to reduce bottlenecks, enhance surveillance and improve user experience—all while strengthening border control.

 

Biometrics and Seamless Passenger Processing

Airports have taken the lead in rolling out biometric technologies to streamline passenger journeys. Singapore’s Changi Airport has introduced a facial and iris recognition system that enables passengers to clear immigration without presenting physical documents. This reduces wait times and improves the accuracy of identity verification, while also limiting physical contact.

In the United States, Customs and Border Protection (CBP) has expanded its use of biometric exit tools, including handheld fingerprint scanners used on jetways to confirm passengers’ identities before departure. The agency has also piloted enhanced passenger processing (EPP) systems in several airports to automate and speed up arrivals for U.S. citizens.

A particularly impactful development has been he launch of the One-Stop Security (OSS) programme. Piloted on routes from London Heathrow to Dallas–Fort Worth and Atlanta, this initiative allows eligible travellers to bypass a second security screening upon arrival. Checked luggage is pre-screened overseas and transferred directly to domestic flights, cutting connection times by up to 50% and marking a new era of international cooperation in aviation security.

 

AI, Robotics and Remote Screening

Artificial intelligence is playing a growing role in enhancing both passenger and cargo screening. In the U.S., AI-driven video analytics are being tested to detect behavioural anomalies in real time, enabling faster response from customs agents. In the UK, airports such as Southampton and Luton have deployed new scanning equipment that allows passengers to keep liquids and electronics in their bags, reducing processing time at checkpoints.

Changi Airport has also introduced a range of touchless systems, from contactless lift buttons to autonomous cleaning robots equipped with UV-C technology. These enhancements, while initially driven by public health concerns, now contribute to more efficient and hygienic airport environments. On the customs side, Singapore’s Customs@SG app enables travellers to pre-declare goods and pay duties online, streamlining checkpoint operations.

Meanwhile, remote screening technologies are changing the way baggage and cargo are handled. The CBP’s international remote baggage screening initiative lets passengers remain airside during U.S. transfers, as their checked luggage is inspected off-site. This not only speeds up transfers but also improves the targeting of high-risk items for inspection.

 

Smart Ports and Container Innovation

Seaports have embraced digital transformation to enhance customs and logistics efficiency. The Port of Rotterdam continues to expand its digital twin infrastructure, using IoT sensors and real-time vessel tracking to monitor cargo flows and anticipate disruptions. This enables customs officials to act early when irregularities appear, improving both security and traffic management.

In Spain, the Port of Algeciras has rolled out 5G-enabled security systems with augmented reality and AI-based decision support. These tools offer real-time visibility on container movements, helping teams respond faster and more effectively to emerging threats.

One of the most promising developments in cargo inspection is the application of muon tomography. This technique uses cosmic-ray particles to scan containers without opening them, providing deeper and more accurate imaging than traditional X-ray systems. The result is faster detection of concealed contraband, with less disruption to port operations.

As global mobility becomes increasingly complex, customs and border agencies are being challenged to evolve. Recent innovations point toward a future where security is more predictive, more automated, and less intrusive—helping to secure borders while keeping people and commerce moving.

 

At Milipol Paris 2025, visitors will be able to explore many of these breakthroughs in airport and port security. Exhibitors such as IDEMIA, Smiths Detection, LINEV Systems, and others will present cutting-edge solutions in access control, scanning technology and integrated border management, offering a first-hand look at the technologies shaping the next generation of global security infrastructure.
