Phoenix Sky Harbor International Airport is integrating biometric technology that will ease the wait time for travelers willing to pay a fee.
Biometric screening company Clear unveiled kiosks with fingerprint and iris scanners Wednesday inside Terminal 4.
The privately-run scanners will be made available at some point at the other terminals.
Clear officials say passengers with a membership will move through a separate line where their identities would be verified with "the tap of a finger or blink of the eye."
But they would still have to go through bag checks and metal detectors.
Annual membership costs $179. An additional family member can be added for $50 per year. Children under the age of 18 can enroll for free.
Sky Harbor is the 25th airport nationwide where Clear operates.
