Just a decade ago, the word ‘biometrics’ would have struck fear into the average traveller. It might have conjured images of intrusive surveillance, 1984-like dystopia, or the end of personal privacy.

Today, it’s far more likely to be encountered without a second thought – unlocking a phone, completing a bank transaction, or passing through an e-gate at the border. What once felt unsettling has become quietly routine.

As our founder, Julian Maynard, makes clear in his opening column to our new aviation brochure, that shift matters; airports are bracing for record numbers of passengers. Seamless processing is no longer a luxury, and instead now an operational necessity. But a global surge in air travel, rising passenger expectations, and the stubborn reality of ageing airport infrastructure means that many terminals simply cannot expand their way out of congestion.

Physical growth is slow, costly, and often constrained. Technology, by contrast, offers a faster and more flexible path forward.

The International Air Transport Association’s One ID initiative proposes a fundamental rethink: rather than repeatedly presenting documents at each checkpoint, passengers share verified information in advance and move through the airport using contactless biometric identification. In effect, your face becomes your passport, boarding pass, and visa, all in one – a single, secure key that unlocks the journey.

Confidence in this approach is rising. Research shows that around 75 per cent of passengers now prefer biometric identification over traditional documents, particularly when it reduces queueing and uncertainty.

Nearly ten years past, when our team undertook a research and development study that explored the use of facial-recognition technology on the UK’s rail network, that statistic was certainly not as high as it is now.

But many airports are capitalising on the shift in public opinion and showing what’s possible. Singapore’s Changi with its Multi-Modal Biometrics System (MMBS), US Airports with TSA PreCheck Touchless ID, and DigiYatra in India are all leading fresh initiatives that allow quick verification without the need for physical documents.

The result is not just speed, but calm – a processing experience that fades into the background.

Closer to home for me, we’ve recently been involved in a data-driven exercise at Sydney Airport, working alongside the Australian Border Force. By consolidating SmartGate kiosk locations, simplifying decision points, and clarifying eligibility requirements, we have helped reduce cognitive load for arriving passengers and significantly enhanced processing times.

The contrast across the region is, however, striking. On a recent trip to Auckland, New Zealand’s progressive Electronic Traveller Declaration allowed for a seamless, pre-processed arrival. But landing back in Australia, I was handed a familiar piece of arrival paper – though trials of a digital passenger card just might change the game from this year on.
