No more boarding pass at PreCheck?
I am in the new TK lounge at IAD awaiting a DL flight to ATL. Just went through the Pre lane here at IAD and I did not have to show my boarding pass. The TSA agent took my ID and ran it through some sort of scanner? It reminded me of the thing they use at the bank to run your check through...
There was a supervisor of some sort (he seemed to be a contractor) watching closely with a pen and paper. The TSA agent then handed me back my ID and sent me (and everyone else I saw in line before/after) through.
Anyone know anything about this?
