The enhanced driver's license will work just like the U.S. passport card.  The RFID chip will broadcast a number that is uniquely tied to you when it enters a radio field.  That number points to your personal information record that is stored on Department of Homeland Security (DHS) servers.  Border officers will then compare you to the record to determine if you should be admitted.  No personal information is stored in the RFID chip on the driver’s license.
