The TSA tests a new scanning device at the Phoenix airport with other airports soon to follow.
The technology, called backscatter, has been around for several years but has not been widely used in the U.S. as an anti-terrorism tool because of privacy concerns.
The security agency’s Web site indicates that the technology will be used initially as a secondary screening measure, meaning that only those passengers who first fail the standard screening process will be directed to the X-ray area. [My italics]
Should make for some great stories in the TSA break room.
