What is a TWIC?

A Transportation Worker Identification Credential (TWIC) is a form of identification issued by the Transportation Security Administration (TSA) to individuals who require access to secure areas of the transportation infrastructure. This biometric credential is designed to enhance security by ensuring that only authorized personnel can enter sensitive locations such as ports, vessels, airports, and railway facilities. A TWIC card contains the holder's name, photo, and biometric data such as fingerprints. It serves as proof that the cardholder has successfully passed a thorough background check and has met the necessary security requirements. Obtaining a TWIC involves an application process, including the provision of personal information and payment of a fee. This credential plays an essential role in maintaining the security and integrity of the transportation industry by controlling access to critical infrastructure.
