The U.S. Transportation Security Administration (TSA) has begun enrolling about 6,000 port workers and other employees at the Texas port of Corpus Christi in the TWIC program. TWIC is being rolled out in multiple phases with smart cards first issued to the maritime sector before being introduced at other transportation facilities. Initially only biometric cards themselves are being rolled out. The readers won’t be in place for another two years. About 1 million transportation workers at 147 ports nationwide are expected to be enrolled into the program by the end of 2008. The Port of Wilmington, Delaware was the first port to enroll in the program.
