Florida Congressman John Mica has hit out at a biometric security card system used at US ports, saying that the Department of Homeland Security (DHS) needs to set specific guidelines on how to read the cards.Mica told US media this week that Homeland Security developed the card without issuing approved readers or rules on how to read or use the cards, complicating its use.According to the Fox13 report, Port Manatee and other ports have purchased systems that do scan and read the cards with grant money – but the systems are operating without specific federal guidelines and with no clear indication of when those rules may be issued.”We gave it our best guess,” said David St. Pierre, director of seaport security at Port Manatee about the Transportation Worker Identification Credential (TWIC) process. “One would have thought they would have that resolved much faster, but it's not.”Mica added: “Now we've got an expensive flash badge – costly to the government, costly for transportation workers, and useless as far as security.”In February, the US House of Representatives passed three Transportation Security Administration-related bills meant to increase the effectiveness of the TWIC programme.Under the Identification Credential Assessment Act, sponsored by Rep. Sheila Jackson Lee, D-Texas, DHS would be required to commission an independent study of the Transportation Worker Identification Credential, or TWIC, program.TWIC is intended to provide tamper-resistant biometric identification credentials for several million workers requiring access to ports and other maritime facilities, subject to a security threat assessment conducted by the TSA that explores the applicant's criminal record, immigration status and other relevant information.
