Criminals trying to enter the U.S. by sea may soon find it more difficult.
The House passed a bill Tuesday requiring the Secretary of Homeland Security to use biometrics to identify terrorists and other suspects.
That's the use of iris scanning, fingerprinting and facial recognition.
A pilot program helped the Coast Guard and other agencies apprehend 600 people with outstanding warrants -- including a repeat human smuggler.
"It ensures people attempting to enter the United States illegally by sea that have criminal records will not simply be returned to their homelands," said Rep. Gus Bilirakis. "They will be detained so they cannot attempt to enter the U.S. again."
Some lawmakers are seeking more funding for the program.
