New Jersey airport travelers may soon be given a choice if they would rather a physical body search or a full body scan.

The Millimeter Wave Machine is a new technology that does a full body scan of passengers during the security screening process. It essentially lets airport security workers see what is underneath clothing.

In secondary screenings, where passengers are asked to step aside, some will now be given the choice of putting the new technology to work. Authorities say those doing the looking will not be permitted any outside equipment such as cell phones or cameras.

Most travelers at Newark Liberty International Airport say they wouldn?t mind the body scan, as long as the images were deleted after the process. Many say they have nothing to hide, so they wouldn?t worry about a scan.

Sky Harbor International Airport in Phoenix is the first airport to put the new machine to use. Authorities say it will soon be installed at New York?s John F. Kennedy International Airport. There is no word on when it will arrive in Newark.
