Virtually all government agencies appended their lists of acceptable documents to include the passport card. At the same time the SSA rejects the passport card even though it is issued by the same agency as the passport book, to the same standards and points to exactly same database? This is indeed ridiculous.
[rant] Having lived in a country that required me to have an internal passport (and carry it all the time), I thought of it as atavism. However, after my various US-issued identity documents were rejected by various US-based agencies and businesses, I really believe now that people would only benefit from a single national identity document that would prove citizenship and identity all together.
