It's easy to have a minor panic when you can't find your travel documents before boarding a flight, as images of not being allowed on flash through your mind।
But new biometric technology could eradicate those worries, as it uses facial recognition to check you in instead, eliminating the need for documents.
And it's already being rolled out. In fact, passengers travelling with Lufthansa will no longer need a boarding pass or passport, on the airline's route from Miami International Airport to Munich.
Instead, through a partnership between the airport, Lufthansa and US Customs and Border Protection (CBP), as well as global air transport IT provider SITA, all passengers will need is a simple photograph taken at the boarding gate.
This will confirm their identity, and authorise their travel. Of course we don't suggest ditching the passport - it's wise to keep your travel documents on you anyhow should there be any issues and you need to produce them.
According to CBP, the whole process will take less than two seconds, with a 99 percent matching rate.
Lufthansa is the first airline to launch the new process, which launched in Miami International Airport last week. The airport plans to launch it with additional airlines throughout 2019.
The new venture follows the airport’s opening of America’s first all-biometric entry facility at Concourse E last year, which screens all international arrivals using facial recognition.
The company says that it has decreased processing times by as much as 80 per cent for participating airlines.
