Rapid Increase in Biometric Data in Airports Raises Privacy Concerns

In 2018, Delta paved the way in airport terminal development, by introducing the first biometric terminal at the Hartsfield-Jackson Atlanta International Airport where passengers can use facial recognition technology from curb to gate. Delta now offers members of its Sky Club airport lounges to enter using fingerprints rather than a membership card or boarding pass. Other airlines use biometric data to verify travelers during the boarding process with a photo-capture. The photograph is then matched through biometric facial recognition technology to photos that were previously taken of the passengers for their passports, visas, or other government documentation.
