"Some Idahoans say new law won't curb terrorism
Some say requiring more ID won't deter illegal immigration"
May 12, 2005
The parties whining in the Idaho Statesman are from the Boise/Nampa area. That is the crowded side of the state to avoid.
I expect the RealID to be implemented with a stack of blank plastic cards with embedded RFID. The outside will probably have an optically scannable bar code with biometric info such as a retinal scan or finger print. The RFID serial number associated with your physical license will get recorded in a database. The same database they are using right now, but augmented with another field for the RFID.
