Trials of security-related technologies are beginning to boom at airports worldwide. Three airports and an airline have recently announced trials of products that identify so-called trusted passengers.

Billund Airport in Denmark has installed a Bluetooth network that will track 300 to 500 volunteer passengers as they move throughout the airport. Schiphol Group NV, which operates the Amsterdam airport, is offering its self-service border control system featuring iris-recognition technology to other airports and airlines. Virgin Atlantic Airways is expected to announced a trial tomorrow for the use of biometrics at Heathrow International Airport in London.
