Will the eventual implementation of digital identification allow TSA to build a national database of identification information?

No. TSA only receives a passenger’s digital identification information at TSA checkpoints with the passenger's consent. Passengers control access to and use of the digital ID kept in their mobile device. TSA does not copy or store the digital ID, unless it is done in a limited testing environment for evaluation of the accuracy of facial recognition technology. In that instance, TSA informs the passenger through signs, advisements, PIAs on tsa.gov and other means.
