All but one of the 19 hijackers on Sept. 11, 2001, had some form of U.S. identification - some by fraud, the 9/11 Commission found. The legislation contains new standards on information contained in birth certificates and driver's licenses, and improved security for Social Security cards. It also establishes new nationwide regulations for how they are issued by states. For birth certificates, new rules will be applied to certification, the type of paper used and how birth and death records are stored by each state. A deadline is also set for implementation of changes to driver's licenses and non-driver ID cards, among them the requirement of digital photos and standards for machine-readable information on the cards. States will be eligible for grants to assist with the changes. Social Security cards will not be replaced more than three times in a year, and no more than 10 times total per citizen. Additionally, states will be prohibited from including Social Security numbers on driver's licenses.
