Biometrics testing at the U.S.-Mexico border

Aiming to crack down on foreigners who remain in the country with expired visas, the federal government is turning to biometrics — and Otay Mesa is slated to be a key test site. Non-U.S. citizens with RFID-enabled documents such as the updated U.S. visa card would “walk through,” Flores said. “As they walk through, we will have an RFID reader, and we will have a device that will read the iris. The intent is to capture individuals while they’re on the move.” The area will also include facial biometric cameras.
