New System Tracks Foreign Travellers At JFK

NEW YORK - JANUARY 5: A foreign traveler holding a visa to enter the U.S. has his finger scanned January 5, 2004 at JFK airport in New York City. Today, JFK began taking finger scans and photographs of people entering the U.S. for the purpose of checking against terrorist watch lists. U.S. citizens and holders of green cards, as well as individuals from 27 countries whose citizens are not required to obtain visas to travel to U.S. are exempt from the requirement. The system, called US-VISIT, for United States Visitor and Immigrant Status Indicator Technology, will be implemented at 115 American airports and 14 seaports. (Photo by Stephen Chernin/Getty Images)
