US: Eye scans are replacing airline boarding passes

Clear, the biometric screening firm long hobbled by a limited network, is landing in several major US airports soon—including New York’s LaGuardia—marking the start of an era that could radically accelerate your trip from curb to cabin. But there are some bumps to smooth out first. Clear, which started at JFK International earlier this month, will open screening lanes at LaGuardia and Atlanta’s Hartsfield-Jackson in the next few days, followed by Los Angeles International and Minneapolis-St. Paul by April. All told, the expansion will put Clear at 22 major airports, covering the majority of domestic American flights. The new option doesn’t replace TSA PreCheck so much as complement it. It checks travellers’ identities with a fingerprint or iris scan, eliminating the boarding pass and identity checks. <br/>
