"Delta and TSA's new bag-drop program rolled out for testing at Atlanta's Hartsfield-Jackson International Airport at the end of October. Travelers will go to a dedicated bag drop area on the lower floor of the South Terminal. At the screen, the attached camera will automatically snap their photo and send it to the Travel Verification Service database, managed by Customs and Border Protection. Upon verification, the pending bag tags print automatically. Attach the tags, put them on the conveyor belt, and head to security like normal. If you've opted in, you'll also be allowed to board your flight without showing a boarding pass or other identification; your face serves as your boarding pass."
