tverbeek tells us about a program the state of Washington has approved, to issue RFID-equipped drivers licenses to facilitate cross-border traffic. The idea is to load the drivers license with information proving citizenship, so that (with Department of Homeland Security approval) the bearer doesn't need to carry a passport — which otherwise will be required to re-enter the US from Canada beginning in 2009. The "enhanced" licenses will require applicants to submit to an in-person interview and to show proof of citizenship. A pilot program in Washington begins January 2008. Officials hope for DHS approval of the program before the Vancouver Olympics in 2010 causes a spike in cross-border traffic.
