Airport security is both slow and ineffective. The random testing of airport security finds that the TSA (Transportation Security Administration) fails to detect weapons 80-95% of the time. The 95% failure rate was from 2001 to 2015. Recent tests have found some improvement to 80%.
New scanning equipment could speed up security checks by 30% and with further integration in a few years, it may no longer be necessary to remove laptops and electronics for separate scanning from luggage.
The new CT (scanning) systems are based on the same technology currently used to automatically screen checked bags for explosives. Those systems are larger and the manufacturers have shrunk the physical footprint of the next-generation systems for checkpoint use. The technology presents images in three-dimensions, enhancing the awareness of operators of a bag's contents.
Within a few years, if the new CT systems are installed at all airports then travelers may no longer have to remove anything from the luggage.
