The TSA has all of your travel data before you fly. They compare who they think you are against their error-prone No Fly List, which denies people the right to travel without any due process hearing.
So it’s strange in a way that they need your boarding pass when you go through security. Once you’ve identified yourself they can match your ID to their secure flight database and they already know your travel plans.
At PreCheck lanes at four airports — Washington National, Washington Dulles, Chicago O’Hare, and Austin — TSA is now testing scanning your ID and not your boarding pass.
Pre-check passengers just need to hand their photo ID to the TSA agent at the security checkpoint. A boarding pass won’t even be required. Then, the TSA agent will scan the passenger’s ID in the credential authentication technology system. The technology is expected to verify the authenticity of the document and cross-reference against the Secure Flight database.

If you believe that the TSA knows who the terrorists are in advance (yet doesn’t have them arrested) then it’s important to check their ID and make sure they aren’t using fake documents. TSA believes this new effort “will enhance detection capabilities for identifying fraudulent documents at the security checkpoint.”
The plan is to roll this out at other airports as well this month.
