British Airways (BA) has begun trialing self-service biometric boarding gates on international flights out of the US.
The new technology, created by Vision-Box, will create a smoother, quicker boarding process as passengers will no longer need to present their passport or boarding pass at the gate—only at check-in and security. Instead travelers look into a camera prior to boarding, wait for their biometric data to be verified, and then walk onto the aircraft.
The biometric gates use high definition camera technology, and allow customers to pass through by recognizing their unique facial features, and reconciling them with the digital facial scan taken as part of the immigration process.
The gates have been installed on three stands at LAX.
Using biometrics helps to speed up the boarding process while maintaining safety and security.
