(CNN) -- Americans may need passports to board domestic flights or to picnic in a national park next year if they live in one of the states defying the federal Real ID Act.

The act, signed in 2005 as part of an emergency military spending and tsunami relief bill, aims to weave driver's licenses and state ID cards into a sort of national identification system by May 2008. The law sets baseline criteria for how driver's licenses will be issued and what information they must contain.
