Homeland Security will determine if the driver's license/ID cards are acceptable and can be used for any official purpose.
It's being handled through Homeland Security because this is another part of the administration's war against terrorism, although it has been noted the 9/11 hijackers were in the United States legally and had legally issued driver's licenses.
Ostensibly, it also will help control illegal immigration while tightening access to the United States. Literally. Besides identification cards, the measure allows Homeland Security to construct physical barriers wherever it deems appropriate for security, be it on the Mexican border, the Canadian border, around government buildings, maybe even along state lines.
While you're thinking about that, you also might ponder the possibility of having to present your driver's license/ID card to cross a state line or get into - or out of - a city, all in the name of national security."
