The Homeland Security Department intends to begin scanning all 10 fingerprints for foreign visitors starting Nov. 29 at Dulles International Airport in Virginia, department officials said Tuesday. Foreigners visiting the United States on visas must have a digital photograph taken and a scan of their two index fingers under the U.S. Visitor and Immigrant Status Indicator Technology program. DHS has built a database of 90 million fingerprints in the four years the program has been in operation.
