Manufacturers of controversial full-body airport scanners are launching software upgrades that would allow the scanners to display a generic figure instead of an actual image of a traveler's body. Each person would generate an image that looks like a person wearing a baseball cap. The TSA is currently testing the software. Meanwhile, the TSA continues to add scanners at airports around the U.S. There are currently 194 full-body scanners at airports around the country, and the TSA hopes to add 1,000 more by the end of next year.
