Charlotte-Douglas is installing new full-body scanners that promise to be less intrusive.

Ed Archer was on his way to Ft. Lauderdale Friday morning. He said he's been through full-body scanners and know how invasive they can be.

“I've gone through them a couple of times but it's a little personal, you know, it just shows everything,” Archer said.

The new machines are similar to the existing full-body scanners, but instead of producing an X-ray image of each individual, a green screen that says "OK" will appear on a small monitor. If an object is detected, a generic outline of a person appears and a yellow dot shows the area on the body a TSA agent needs to be concerned about.

Right now, Charlotte-Douglas has four scanners in place. By mid-summer, it will have 11 and every passenger who comes through the airport will have to pass through one.
