There is one hitch. The licenses must be verified. But Linda Daschle (formerly of the FAA) is working on that:
SECURITY IN LOBBYING (Daschle's wife to work for Intelli-Check. A tie-in to a National ID?)
Linda is also a lobbyist for the airline industry. I suspect we'll see airlines requiring drivers licenses be checked by Intelli-Check very soon. And from there, the machines will spread.
