TSA is stupid, but even I find it hard to believe that they are that stupid as to not realize this was readable with very rudimentary tools. And to suspend PreCheck, as I've already said in other threads, would be to admit that TSA made a mistake, which they categorically do not do.

If anything, I think this will coincide with PreCheck becoming a membership-based program and it will be an excuse to get people to submit to a background check and pay a fee. No different really than GE (other than the competency level of the administering agency).
