Schiphol is working with iris recognition technology provider Joh Enschedé to sell the system around the world because international interest since it was launched last October has been "enormous," said Marianne De Bie, a spokesperson for Schiphol Group.
No deals have been signed yet but initial contacts have been made with European and US airports and airlines, De Bie said.
About 1,200 frequent travellers have been issued passes for the Dutch system, dubbed Privium. Pass holders do not have to stand in line for customs but instead go through a special passage where their iris geometry is compared with the iris information stored on the pass, after which an automatic gate opens. Feedback from users has been good, according to De Bie.
Iris recognition is a form of biometric identification. Other types include fingerprinting, palm recognition and facial scans. Iris recognition is seen as one of the most reliable types as the iris, the coloured portion of the eye, never changes, according to Schiphol.
Schiphol Group developed Privium in close cooperation with the Dutch border police and the Dutch department of immigration and naturalisation.
