Salt Lake City International Airport has released new credential authentication technology (CAT) to improve airport safety. First generation CAT units are designed to scan a traveler’s photo identification, confirm the traveler’s identity as well as their flight details. The new CAT units, referred to as CAT-2, have the same capabilities, but are also equipped with a camera that captures a real-time photo of the traveler.

CAT-2 compares the traveler’s photo on the identification credential against the photo captured by the machine. Once the CAT-2 confirms the match, a TSA officer will verify and the traveler can proceed to security screening, without ever exchanging a boarding pass. TSA officers can perform additional passenger verification if needed.

Photos captured by CAT units are never stored or used for any other purpose than immediate identity verification by a TSA officer. Travelers who do not wish to participate in the facial matching process can opt out in favor of an alternative identity verification process.
