AP - Border checkpoint scans eyes, faces of departing foreigners
The AP reports: "The federal government is using eye scans and facial recognition technology for the first time to verify the identities of foreigners leaving the United States on foot — a trial move aimed at closing a longstanding security gap, officials announced Thursday. Before now, foreigners who left the country were rarely checked by U.S. authorities as they walked into Mexico or Canada through ports of entry. The checkout system that launched Feb. 11 at a busy San Diego border crossing with Mexico aims to ensure those who enter the country leave when their visas expire and identify those who violate that. Up to half of the people in the U.S. illegally are believed to have overstayed their visas."
