In November, Delta Air Lines launched a new digital identity program for T.S.A. PreCheck members at Hartsfield-Jackson Atlanta International Airport who can opt in to using facial recognition to do everything from checking a bag to clearing security and boarding their domestic flight.

Opting in requires the passenger to enter their U.S. passport number, which provides the back-end check on your identity using your passport photo, even though the new program is domestic only.
