Depends a lot on what state you reside. I did see the part in the wiki article:
"The Court accepted the Nevada supreme court's interpretation of the Nevada statute that a detained person could satisfy the Nevada law by simply stating his name. The Court did not rule on whether particular identification cards could be required, though it did mention one state's law requiring “credible and reliable” identification had been struck down for vagueness."
