Facial recognition technology is being implemented at U.S. airport security checkpoints, utilizing Credential Authentication Technology (CAT) since late 2022. As of summer 2023, CAT-2 machines were in operation at 84 airports, with plans for installation at over 400 locations. The technology matches travelers' faces with images from identification documents. TSA asserts that images are not stored long-term. Travelers can opt out, but must inform TSA agents before scanning their ID to avoid automatic image capture. Legislation like the Traveler Privacy Protection Act seeks to regulate the use of this technology.
The Transportation Security Administration has been rolling out Credential Authentication Technology since late 2022, with CAT-2 machines currently in use at 84 U.S. airports.
TSA states that the images captured during biometric screening are not stored except for a limited period of time for testing and evaluation purposes.
Travelers can opt out of biometric screening, and they are advised to inform TSA agents before putting their ID in the scanner to avoid image capture.
The Traveler Privacy Protection Act, introduced by U.S. senators, aims to impose restrictions on the TSA's use of facial recognition technology to protect travelers' privacy.
