Wait until all the State Driver's Licenses become smart cards and use those to verify identity. Similar to the PIV/HSPD-12 cards the U.S. government uses for employees. Require PINs just like with ATM cards.
With the card being an actual computer that can store secure digital certificates, and the same trust model the entire country uses now -- your government-issued Driver's License (and/or Passport) is accepted by pretty much EVERYONE as proof of identity -- this is doable.
