U.S. Customs and Border Protection (CBP) has announced that it will begin collecting biographic and biometric data from some foreign national travelers in a test program when they depart the United States at Atlanta’s Hartsfield-Jackson International Airport

The biometric and departure data will be collected through use of an “enhanced mobile device” that will allow CBP to record exit information efficiently and streamline inspection queries for foreign national travelers. All test passengers will have their fingerprints and passports scanned by a CBP Officer using the mobile device on the loading bridge of selected flights departing the U.S. Each traveler’s departure data will be matched to the digital biometrics information that was collected when he or she arrived in the country. This information will be stored and managed by the U.S. Department of Homeland Security (DHS). Only non-U.S. citizens will have their information collected and processed.

The test program is expected run through June 2016, eventually expanding beyond Atlanta into the following major air travel ports: Chicago, Dallas, Houston, Los Angeles, Miami, Newark, New York, San Francisco, and Washington-Dulles.
