From the New American :
 The REAL ID Act, signed into law by George W. Bush on May 11, created our country's first national identification card.

The measure imposes federal standards on state driver’s licenses, and creates a huge central identification database — which will be shared by the governments of Mexico and Canada. The law also “gives authority to the Secretary of Homeland Security to unilaterally add requirements as he sees fit,” noted Rep. Ron Paul (R-Texas), an opponent of the act. Those requirements, in short order, will probably involve the use of “biometric identifiers,” such as retinal scans.

It is interesting that not only Americans comes under our Administration and Homeland Security's database, but also Canada and Mexico. Now since identifying requirements can be added in the future, is this not leaving open the door for a subdermal ID requirement ? Time will tell.
