US expands facial recognition at border, airports

The U.S. will expand the use of facial recognition technology to track non-citizens entering and leaving the country in order to combat visa overstays and passport fraud, according to a government document published on Friday.

A new regulation will allow U.S. border authorities to require non-citizens to be photographed at airports, seaports, land crossings and any other point of departure, expanding on an earlier pilot program.

Under the regulation, set to take effect on December 26, U.S. authorities could require the submission of other biometrics, such as fingerprints or DNA, it said.
