ATLANTA -- The next time you fly out of Hartsfield-Jackson International Airport, you may notice new security measures.

Delta is partnering with the U.S. Department of Homeland Security testing new biometrics which verify the identity of passengers leaving the country.

While many travelers will tell you they want top-notch security, at the same time, they want convenience. Unfortunately, those two ideas don't always line up but a new technology may solve both problems.

Delta is one of the first U.S.-based airlines to try this technology. Some of the details are still being sorted out but we do know it works by scanning your face, iris, and fingerprint and comparing that data to your passport as you return to the U.S. The goal is to make it more difficult for someone to steal your identity.

Officials said this is a good way to increase security and convenience at the same time. 11Alive spoke to several Delta international flyers. Here's what some customers had to say.

"Anything that's going to make us safer is a good move," traveler Cheryl Wolfinger said.

Juan Menda agrees.

"I think anything that makes it faster and more secure is a win-win for everybody," he said.

This is being tested at a few gates now as well as at JFK with more coming by the end of the summer.

One major question is what is done with those facial images once they are taken. Officials said those images are erased and not stored.
