The Registered Traveler Pilot Program was an airline passenger security assessment system tested in the United States air travel industry in 2005. It was used in several U.S. airports in a voluntary pilot phase and continues in operation in several airports around the country. It is administered by TTAC, the Transportation Security Administration (TSA) office responsible for Secure Flight, the replacement for the Computer Assisted Passenger Prescreening System (CAPPS) and the canceled CAPPS II counter-terrorism system. Registered Traveler is a public and private partnership between the TSA and the Registered Traveler Interoperability Consortium (RTIC) providing rules and standards for private Enrollment Providers that sign up participants. At 11:00 p.m. PST on June 22, 2009, Clear (the largest of the three companies offering the Registered Traveler program) ceased operations because Clear and its parent company, Verified Identity Pass, Inc., filed for bankruptcy. The company was then acquired by Alclear LLC and "Clear lanes" were opened at Denver International Airport, Orlando International Airport, Dallas/Fort Worth International Airport, and San Francisco International Airport. Clear is currently operating at 60 airports, airports, stadiums, and other venues nationwide as of January 2020. Overview The program seeks to identify passengers who pose a minimal security risk, and then provide those passengers an enhanced security checkpoint experience. Passengers will voluntarily pay a fee and submit to a background check to become a Registered Traveler. Passengers who pass the background check will be issued a smartcard credential for use at the security checkpoints of airports that participate in the program. Registered Travelers will have access to a reserved security lane and will enjoy a shorter wait at the security checkpoint. Other benefits, such as allowing Registered Travelers to keep their coats and shoes on and their laptops in their bags have also been discussed. Any U.S. citizen or lawful permanent resident over the age of 18 can apply for membership, as can minors over the age of 12 with parental or guardian sponsorship. In order to prevent a terrorist with a clean background from compromising the system, the TSA requires that registered travelers undergo the normal TSA screening (baggage x-ray and personal metal detector), at the RT kiosk checkpoint. Additionally, Registered Travelers are not exempt from random secondary screening and may not bring prohibited items into secure areas of terminals.
