Americans may need passports to board domestic flights or to picnic in a national park next year

Colorado and New Hampshire lawmakers are not alone. Groups like the American Civil Liberties Union and Electronic Frontier Foundation say the IDs and supporting databases -- which Chertoff said would eventually be federally interconnected -- will infringe on privacy.

EFF says on its Web site that the information in the databases will lay the groundwork for "a wide range of surveillance activities" by government and businesses that "will be able to easily read your private information" because of the bar code required on each card.

The databases will provide a one-stop shop for identity thieves, adds the ACLU on its Web site, and the U.S. "surveillance society" and private sector will have access to the system "for the routine tracking, monitoring and regulation of individuals' movements and activities."

The civil liberties watchdog dubs the IDs "internal passports" and claims it wouldn't be long before office buildings, gas stations, toll booths, subways and buses begin accessing the system.
