Iris scanning is supposed to assess a biometric analysis of who you are, like finger prints, only faster and easier to automate. The iris scanning machines won’t get you to the boarding gate straight away, but they will get you first in line for TSA’s gropers and X-rays. Users who fly a lot claim it cuts waiting in line and checkpoint hassles considerably. For that advantage, you’ll have to pre-register with CLEAR’s pre-security system, and purchase unlimited use for one at $179.00 annually. The TSA has versions of its own pre-screening system using similar technology, which seems to be more concerned about international travelers.
Only frequent flyers should bother applying. Although TSA’s system charges nothing for registering, it appears that their pre-check system isn’t available to everyone. To see if you qualify with TSA’s pre-check system, go here: (http://www.globalentry.gov/) Very few airports have these systems at the time of this writing. But that’s expected to increase with time. With either system, registration requires starting the application online. Then bringing your driver license, passport (or other ID), your eyes and a finger to a station where they can scan your iris, fingerprints, and current photo in with all that other stuff.
