A new policy across US airports that will collect facial recognition data from noncitizens entering and leaving the country comes into effect today.

The measure is designed to curb visa fraud, identify criminals, detect overstays and prevent illegal reentries, the Department of Homeland Security (DHS) said.

Going forward, visitors from abroad will have their facial biometric data collected when they come into and leave the country by US Customs and Border Protection (CBP).
