More technology is about to be employed against foreign visitors to the U.S.

"In a high-tech strategy against terrorists, the government will soon begin comparing foreign travelers with digitized photographs and will consider plans to encode their travel documents with personal data that can be read electronically."

"Starting this month, the State Department will relay digital images of foreign travelers to U.S. ports of entry. For the first time, immigration officials will be assured that they are comparing the travelers who stand before them to authentic pictures taken when they applied to visit the United States."

"In addition, Congress may approve legislation to mandate unique, personal identifiers -- such as digitized fingerprints -- on visas that the State Department grants to foreign nationals who wish to travel in this country, as well as on the passports of 29 nations. The bill passed the House on Dec. 19 and enjoys broad support in the Senate. "
