How do passengers know they are not required to participate?

TSA posts signs at checkpoints using facial recognition technology. The traveler’s right to decline a photo is highlighted in the sign, on passenger-facing screens, in officer advisements, and on TSA.gov. Also, TSA publishes Privacy Impact Assessments (PIAs) to notify the public  about facial recognition technology and additional information on privacy protections.
