The Department of Homeland Security has a new security system that's literally aimed at your fingertips.

It is a biometric system that grabs your index fingerprint and your photograph and compares them to the national and international watch lists.

The program is called is U.S. Visit. It is already up and running in a few other airports around the country.

"Most recently we had a gentleman who actually had a warrant for his arrest out of Dallas," explained Bob Mocny of U.S. Visit. "We were able to remove him from the plane because his finger scans matched those of someone with this active warrant."

This really isn't something new for foreign travelers because for the last year and a half they've had to go through this process when they've come into the country. Starting May 18 they also have to do it when they leave.

Baljeet Malhotra is a software engineer from India and he's one of the first to try out the system Wednesday.

Sea-Tac Airport predicts up to 500 foreign travelers will get checked each day.

"It doesn't hurt me because it makes it safer," said Malhotra, "and I personally don't see anything wrong with it."

Right now it's only being used to check foreign citizens as they leave, but this system could easily be used to track U.S. citizens if congress approves.

But critics fear that smacks of Big Brother invading their privacy.

So far 25 million visitors have gone through the system at airports across the country and it has identified 590 criminals or immigration violators.
