Facial recognition may soon be coming to an airport security line near you.

Earlier this week , the Transportation Security Administration released a 23-page report outlining changes it is proposing on how passengers are screened before boarding their flights. Key among those changes is the proposal that passports and other forms of identification will eventually be replaced by biometric technology.

“With the threat to aviation evolving every day, developing the next generation of security technology with our industry partners is critically important,” David Pekoske, the T.S.A. administrator, said in a statement. “By expanding our use of biometrics, TSA secures its position as a global leader in aviation security and advances global transportation security standards.”

Early this year, the agency began testing facial recognition technology for international travelers at Los Angeles International Airport. The biometric technology matches facial images to photos in government databases, such as photos obtained from passports or visa applications.

And in 2017, the T.S.A. tested fingerprint technology at the T.S.A. PreCheck lanes at the Atlanta and Denver airports. The technology matches passenger fingerprints provided at the checkpoint to those provided to the T.S.A. by travelers who have enrolled in the PreCheck program.
