The Department of Homeland Security wishes to incorporate by reference Mobile Driver's License standards (ISO/IEC 18013 series) into the rules for TSA and REAL ID, and several states have already implemented compatible IDs. Each ISO standard costs hundreds of Swiss francs to read, and you must agree not to share a copy with anyone else.
How much is it reasonable to have to pay to see the privacy and security details of the basic government infrastructure you rely on?
