Since the federal government began letting select frequent fliers with new high-tech passes speed through airport security checkpoints, one of the biggest complaints has been that the year-old program is too limited to be of much use.

Now, a privately run version coming online in Florida could spur efforts to broaden the program – and boost media entrepreneur Steven Brill’s vision of installing such a system across the nation at airports and other security-sensitive locations.

Beginning June 21, the Orlando airport will let travelers pay $80 a year for a card that guarantees an exclusive security line and the promise of no random secondary pat-down. To get this new “Clear” card, travelers would have to be vetted by the Department of Homeland Security and submit to fingerprint and iris scans.

Similar systems exist at some European airports, and in five U.S. airports as part of a test by the Transportation Security Administration.

But the TSA’s “Registered Traveler” program, which is free for now while in its test phase, has been capped at 10,000 participants, and cards obtained at one airport don’t work at others.

The company behind Clear is Verified Identity Pass Inc., which Brill founded in 2003 with hopes of creating a nationwide, voluntary system that would give prescreened people a dedicated fast lane for entering secure areas – not only at airports but also office buildings, power plants and stadiums.

Brill, the founder of Court TV and American Lawyer magazine, argues that while more rigorous security checks are needed since the Sept. 11, 2001, attacks, it doesn’t make sense for everyone to have to go through them.

Armen Derhohannesian, of Hampton, N.H., verifies his fingerprint at the American Airlines terminal at Logan Airport in Boston during a 90-day pilot program allowing frequent fliers to cut down on their airplane boarding times. A privately run version of the high-tech passes will soon get a test run in Orlando.

New York-based Verified ID has attracted such investors as Lehman Bros. and Lockheed Martin Corp., which is providing the technology for Clear. But until the Orlando deal, Verified Identity Pass had not snared a customer.

Brill says he has had talks with about 20 other airports.

He’s giving them good reason to listen: In its proposal to Orlando officials – which beat a rival bid from technology integrator Unisys Corp. – Verified ID promised to share 29 percent of Clear’s first-year revenue with the airport authority and as much as 22.5 percent in succeeding years. The airport also would get 2.5 percent of Clear’s future nationwide revenue.

The proposal says Verified ID expects to have 3.3 million members across the nation within six years, with annual memberships likely costing $100.

That kind of participation is well beyond the scope of the TSA’s Registered Traveler tests, which have been limited to certain airlines’ passengers at Boston, Los Angeles, Houston, Minneapolis-St. Paul and Washington-Reagan airports. A separate, older program, known as INSPASS, lets frequent international travelers whisk through some U.S. Customs checkpoints with the use of hand-shape biometrics.

Not everyone, however, is ready for trusted-traveler programs to take off.

Privacy watchdogs have questioned how fliers’ personal data will be handled.

Others worry fast lanes will be tempting to terrorists whose records are clean enough to earn them a “trusted” label.
