There is no law as far as I know that requires one to carry any form of ID on them. The only law/requirement is that when one is stopped by a member of the law enforcement community, that they ID themselves when asked. That can be as simple as giving the LEO your name, address and SSN if asked, or by showing them your drivers license (if one drives) or state ID, school ID, military ID.
It is also my understanding that if said member of the law enforcement community has reason to believe that you are being deceitful in the information that you have given them that they can detain you until they have ascertained that the information is correct.
