The TSA is Testing a Scanner That Might Speed Up Security
Summary: The TSA is finally updating its decades-old security systems. On Thursday, it began testing a computed tomography (CT) scanner on carry-on luggage in Phoenix. Thanks to the CT scanner, passengers can now leave their technology and liquids in their bags when passing through airport security, meaning lines would speed up by up to 50 percent. In addition to making everyone feel like they have TSA PreCheck, the CT scans improve detection by showing 3D images of the contents in a carry-on.
