With passengers getting familiar with biometrics as the norm for secure travel, the requirement to carry a passport around at the world’s busiest airports is getting less and less. Although it is still good to have a back-up document.

Essential travel requirements have changed during the era of automated immigration clearance systems based on facial recognition.

Singaporean ministers have announced that 2024 will be the turn of Changi Airport to undergo a thorough refurbishment and installation of readily-available automated e-gates that can manage spikes in passenger travel.

And Singapore’s immigration laws are expected to align more with the pace of deployments from Monday, which will satisfy some ministers raising concerns over cybersecurity.

Biometrics along the end-to-end passenger journey will include all automated procedures from bag check-in to reading flight information in real-time.
