Dutch carrier KLM is trialing a new biometric boarding technology at Amsterdam's Schiphol Airport that allows passengers to go through the gate without showing a document.
The solution, developed by electronic identity solutions company Vision Box, uses facial recognition. Its goal, Vision Box said, is to expedite passenger boarding.
The three-month trial is being undertaken at just one KLM gate at Schiphol. There, passengers who wish to participate can register at a kiosk by scanning their passport and boarding pass and having their photograph added to a database.
Then, when they go through the biometric eGate, passengers will be scanned by a second camera but won't need to show any documents.
Vision Box isn't the only technology company working with biometrics in an effort to smooth the airport experience.
Rockwell Collins has developed a system that relies on an infrared camera, which photographs passengers at check-in and stores their biometric data in the cloud.
A second infrared camera would be deployed at the security checkpoint, verifying a passenger's identity and alleviating the need to present identification or a ticket to an agent.
Similarly, the infrared camera could be used at boarding and at entries to airport lounges.
That technology was on display in October at the Future Travel Experience Asia Expo in Singapore
. Rockwell Collins said at the time that the system was expected to get a trial run at London's Heathrow Airport this winter. On Friday the company would only say that they are expecting to do several trials, but they did not reveal when or at which airports.
