The Transportation Security Administration is determined to make facial recognition and other biometrics a regular part of the airport experience, and it now has a roadmap for that expansion. The effort will start by teaming with Customs and Border Protection on biometric security for international travel, followed by putting the technology into use for TSA Precheck travelers to speed up their boarding process. After that, it would both devise an "opt-in" biometric system for ordinary domestic passengers and flesh out a deeper infrastructure. While this will include technology like fingerprint readers (primarily for trusted passengers), face identification will remain the "primary means" of verifying identities, the TSA said. As such, you can expect facial recognition to play a major role.
