Iris-recognition technology is now being used at the Dubai airport, with an automated two-gate system:
Scanning your passport opens the first gate; an iris print opens the second. Once the system is fully deployed, the company says it will bring wait times down from 49 minutes to 22 seconds. A private company called Clear is already trying this on an opt-in basis in the US. In exchange for a quick iris scan, their service will let you skip security in half a dozen American airports.
The bargain is simple enough: In exchange for one more biometric, you get to skip an hour in customs, or the indignity of a TSA checkpoint search. And as an ID technology, it simply works better. It’s less invasive, harder to fake (although still possible), and more effective at everything we want ID tech to be good at.
