When the government moved a few years ago to a new electronic passport designed to foil counterfeiting, GPO led the work of contracting with vendors to install the technology.

Each new e-passport contains a small computer chip inside the back cover that contains the passport number along with the photo and other personal data of the holder. The data is secured and is transmitted through a tiny wire antenna when it is scanned electronically at border entry points and compared to the actual traveler carrying it.

According to interviews and documents, GPO managers rejected limiting the contracts to U.S.-made computer chip makers and instead sought suppliers from several countries, including Israel, Germany and the Netherlands.

After the computer chips are inserted into the back cover of the passports in Europe, the blank covers are shipped to a factory in Ayutthaya, Thailand, north of Bangkok, to be fitted with a wire Radio Frequency Identification, or RFID, antenna. The blank passports eventually are transported to Washington for final binding, according to the documents and interviews.

The stop in Thailand raises its own security concerns. The Southeast Asian country has battled social instability and terror threats. Anti-government groups backed by Islamists, including al Qaeda, have carried out attacks in southern Thailand and the Thai military took over in a coup in September 2006.

The Netherlands-based company that assembles the U.S. e-passport covers in Thailand, Smartrac Technology Ltd., warned in its latest annual report that, in a worst-case scenario, social unrest in Thailand could lead to a halt in production.

Smartrac divulged in an October 2007 court filing in The Hague that China had stolen its patented technology for e-passport chips, raising additional questions about the security of America’s e-passports.
