Get through security with fingerprint or eye scan

No one likes to wait on security lines, so a New York tech company is promising a solution that's right at your fingertips, literally.

"Your fingers or your eyes become the key to your verified identity," explained David Cohen, the chief administrative officer of Clear.

Clear uses biometrics: human characteristics like your fingerprint or eye scan to verify a member's identity. The technology is certified by the Department of Homeland Security. Cohen said it promises speed and consistency.

Clear kiosks and dedicated lanes are already in 21 airports across the country, including New York's LaGuardia and Kennedy airports allowing travelers to skip having their ID checked by a TSA agent and go right to the screening line. They're also at six stadiums, including Citi Field and Yankee Stadium, and are on display at Grand Central Terminal for the next two months.

"With just a tap of a finger or a blink of an eye, you're through the checkpoint into physical screening without having to take out a license, passport or any other form of government identification," Cohen said.

But cyber security experts say the convenience offered by Clear comes with serious concerns.

"The big concern is, where is that data being stored?" said Sam Kassoumeh, the chief operating officer and co-founder of Security Scorecard. He said that while passwords and credit card numbers can be changed if they're compromised, biometrics can't.

"You can't change your facial geometry or your fingerprint -- those things are permanent," Kassoumeh said. "So if a hacker gets a hold of that information, they could do detrimental damage to your reputation."

Cohen said Clear takes security very seriously.

"The integrity of that data is frankly the integrity of our company," Cohen said. "We do our best to use best available technology to make sure it's secure."

Frequent flier David Tyree, who checked out the technology at Grand Central, said he is willing to take that risk.

"Would I be offended by my information being shared? Of course I would but I think these days we live in a digital world," Tyree said. "You've got to start trusting at one point or another in this world or you're going to be left behind."

Clear costs $179 a year, though discounts are being offered at the Grand Central pop-up kiosk through July.
