The TSA Rap Back (Record of Arrest and Prosecution Back) program is a high-tech security initiative that allows the Transportation Security Administration to receive real-time notifications of any criminal activity involving individuals in "trusted" positions. Before this program, background checks for airport employees, pilots, and Hazmat drivers were "point-in-time," meaning a person was checked once and then might not be screened again for years. With Rap Back, the TSA is continuously monitored by the FBI’s biometric database. If a person with a security credential is arrested or has a significant change in their criminal record anywhere in the country, the TSA is notified immediately. This "continuous vetting" ensures that individuals who pose a potential threat are identified and have their access revoked instantly, rather than waiting for a periodic renewal of their background check. For the general public, this means a significantly higher level of "behind-the-scenes" safety, as every person with a badge at the airport is being scrutinized daily against the latest law enforcement data to maintain the integrity of the aviation secure area.
