How will passengers know that they are not required to participate?

TSA will provide English and Spanish signage at the airport in close proximity to the dedicated test lanes to provide immediate notice to passengers. TSA personnel monitoring the CAT-C testing will have English and Spanish hand-outs available that provide additional information about TSA’s screening technology and data protection procedures. These signs and hand-outs will also notify the public that participation is completely voluntary.
