Airport screening: The newand you
Companies around the world are pouring research money and brainpower into making the slog through airport security into more of a stroll. Ideally, these innovations improve safety and convenience. But some technologies would require passengers to reveal more personal information than U.S. travelers are used to providing.
What it does
A scanner checks bottles without opening them, determining, for example, whether that pale liquid is a bomb ingredient or ginger ale.
When you may see it
Some now, more later. The TSA already analyzes liquids that are exempt from the 3-ounce rule, such as medicines.
How it may be better
Current analyzers take 20 seconds too long to be used for every soda and shampoo. Ideally, you won’t have to take liquids out of your bag.

How it works
A device shoots a laser through the bottle and compares the wavelength pattern to those of bomb-making chemicals. Researchers are studying technologies that don’t require lasers.
