There is much more to the law. #29 above just lists what is required to get such a card, what shall be printed on it, what databases it shall be linked to and who has access to that information. Go to http://www.thomas.loc.gov and look up the bill number there.
By the way, Dr. Paul is correct that this information is to be shared with Mexico and Canada. Section 203(a) requires that "To be eligible to receive any grant or other type of financial assistance made available under this title, a State shall participate in the interstate compact regarding sharing of driver license data, known as the 'Driver License Agreement', in order to provide electronic access by a State to information contained in the motor vehicle databases of all other States."
This "Driver License Agreement", contrary to the impression contained in the bill, includes not only states of the USA but also any "territory of Canada or any state of the Republic of Mexico or the federal district of Mexico." Source
