Perhaps we're being overly dramatic here. Crain's Detroit Business reports that facial recognition software will be rolled out at all international gates, sparing travelers "the hassle of finding tickets and passports" and making boarding more time-efficient. The system has been tested for years in Atlanta, Delta Airlines' home city, and will expand to Detroit, a Delta hub, in December.
Annalise Frank writes:
Travelers can still opt out of use and proceed as usual. Less than 2 percent have opted out so far in Atlanta, according to Delta.
For passengers trying it, they should still bring a passport.
Here's how it works:
- Enter passport information during online check-in
- Click "Look" on the screen at the lobby kiosk where you're checking in, or approach the camera when boarding or at a TSA checkpoint
- Wait for a green check mark to appear on the screen
- Walk through
"We're removing the need for a customer checking a bag to present their passport up to four times per departure, which means we're giving customers the option of moving through the airport with one less thing to worry about, while empowering our employees with more time for meaningful interactions with customers," [a Delta executive] said in the release.
The time saved per passenger averages two seconds. Presumably, it adds up.
