Since biometrics were introduced to the US airports market more than a decade ago, the uptake has still been pretty slow in adopting broad biometric measures.

Recently however, the US Customs and Border Protection (CBP) has been making sounds in favour of the introduction of greater levels of biometric technology across the country, particularly facial recognition.

How does facial biometric recognition work?

Facial biometric recognition technology can process information quickly – near real-time – and unobtrusively within the airport environment.

In simple terms, the way the system works places a camera within the airport, typically at passport control or other security area, and compares a live image of the travellers’ face with their travel documentation to determine an exact feature match. Using an automated biometric facial matching identification system, the process can be completed in seconds, speeding up the system of passenger processing significantly.

This increased efficiency is key to improving airport operations, particularly when integration with other airport systems can take place.

The trouble is that in the US, governments and departments cannot decide whether investment into biometric technology, both financial and resources, is for the public or the private sector. However, inroads are being built, as the CBP has announced the intention to use biometrics for foreign nationals leaving the US.

There is little doubt across the aviation industry, particularly within the commercial airlines sector, that biometric technology is the way forward for airport security and borders management. One of the key factors in favour of biometrics, aside from the efficiency factor, is the elimination of potential human error in checking travel documentation.

Travellers, according to the experts, could expect to be using their faces as boarding passes within the next three to five years, once infrastructural and operational challenges and investments can be shaken out within the industry. As passenger experience seems to be high on the agenda for the major players in the industry, biometric technology could be a real possibility.
