I saw a sign in the Precheck Lane at Terminal 1 at HNL this morning with the following two links:
https://www.tsa.gov/biometrics-technology
https://www.tsa.gov/digital-id
The TDC was using the camera and having passengers place their ID on a scanner, but I did see that there was a reader for the digital ID, and the sign indicated that using an eligible digital ID was possible. I don't have the California DMV Wallet App since before going to the TSA link I didn't know such a thing existed for CA. (It appears to be in a pilot stage for CA.) I can look to enroll next week if possible and report back since SJC is on the list.
