This somewhat cryptic blog post at Wired reflects the delight of Roger Clarke that the Australian national ID card has been dropped by the incoming government. Clarke wrote an article in 1994 that is probably fairly regarded as the foundation of identitifcation theory. I expanded on his thinking in my book, Identity Crisis.
In related news, Montana Senators Max Baucus and Jon Tester put language prohibiting the expenditure of federal funds for development of a national ID card in the omnibus spending bill Congress passed last week. Because the Department of Homeland Security denies that REAL ID is a national ID, this language is probably hortatory during the current administration.
