Department of Homeland Security’s (DHS) Automated Biometric Identification System (IDENT). In 2014, TSA expanded TWIC® security threat assessment recurrent vetting capabilities by enrolling TWIC® applicants in the U.S. Since TWIC® was launched in 2007, TSA has conducted recurrent vetting of cardholders through the terrorist screening database and vetted individuals who may be wanted by police and/or who may have warrants out for their arrest via the National Crime Information Center. TWIC® recurrent vetting provides near real-time continuous monitoring of the eligibility status of approved TWIC® applicants for the length of the valid security threat assessment.
