As of January 2006 all issued U.S. passports carry an RFID microchip embedded with personal information, including name, nationality, gender, date of birth, place of birth and a digitized photo.

Government officials have repeatedly assured privacy advocates and the public that the personal information on the chips is secure, and that the technology will make it more difficult to forge passports and enter the country illegally.

It seems however that they are not that secure. Recently a hacker with easily acquired equipment was able to copy a few RFIDs while tooling around San Francisco in his car.
