The Register noticed that a senior US Department of Homeland Security official has floated the idea of requiring citizens to produce federally compliant identification before purchasing some over-the-counter medicines — specifically, pseudophedrine. The federal ID standard spelled out by the REAL ID act has been sold as applying only to air travel and entry to federal buildings and nuclear facilities. A blogger on the Center for Democracy and Technology site said, "[The] suggested mission creep pushes the REAL ID program farther down the slippery slope toward a true national ID card." Speaking of federal buildings, CNet has a state-by-state enumeration of what will happen on May 11, when REAL ID comes into effect, to citizens who attempt to enter, say, the Washington DC visitors bureau.
