…It was business as usual, until some approached a line that was almost empty. One by one, they walked to a kiosk with an iPad affixed to it and had their photos taken, as a security officer stood by. Within seconds, each passenger’s image was matched to a photo from a government database, and the traveler was ushered past security into the deeper maze of the airport. No physical ID or boarding pass required.

Some travelers, despite previously opting into the program, still proffered identification, only for the officer to wave it away.

This passenger screening using facial recognition software and made available to select travelers at La Guardia by Delta Air Lines and the Transportation Security Administration, is just one example of how biometric technology, which uses an individual’s unique physical identifiers, like their face or their fingerprints, promises to transform the way we fly.
