The airline intends to implement this tech throughout Atlanta’s international airport terminal.

The new Delta facial recognition technology will soon be rolling out to provide travelers with “curb-to-gate” seamlessness. The first launch from the airline will occur at Hartsfield-Jackson Atlanta airport’s International Terminal F.

The concept is to use facial recognition technology to skip ever having to show documents.

The Delta facial recognition “curb-to-gate” technology, if it works as advertised, will let a traveler heading overseas head through the airport to his or her flight without having to take out any documents along the way. The only step that needs to be taken is scanning by a camera.

The curb-to-gate program will roll out this year, said Delta Airlines. The ATL Terminal F will become “the first biometric terminal in the United States.” There, travelers will be scanned by facial recognition tech when using the self-service check-in kiosks, as well as when they check their luggage in the airport lobby. They are also scanned as they head through the TSA checkpoint and then finally once more as they actually board their plane.

International passengers arriving at ATL Terminal F will also experience Delta facial recognition.

Upon arriving at the terminal, international Delta passengers will be scanned as they head through U.S. Customs and Border Protection Processing. That said, it must be noted that international travelers will still be required to present their passport info when they complete an online check-in. Moreover, Delta advises all international travelers to carry their passports with them regardless of whether or not they’re traveling through an airport with facial recognition technology.

To use the “curb-to-gate” facial recognition, travelers need only approach the Terminal F lobby cameras. When they reach the TSA checkpoint as well as their gate to board their flight, they can tap the “Look” on the screen. Then, all they need to do is look at the screen until the green check mark appears, according to an SF Gate report.

The airline underscored that the Delta facial recognition is completely optional for any travelers heading through Terminal F. “If customers do not want to participate, they just proceed normally, as they’ve always done, through the airport,” said an airline spokesperson.
