It's a grey colored card that is a certain shade that is what camera meters are calibrated as their basis for determining the correct exposure. So if you're outside, you have a three objects of different colors. The same light is shining on each thing, but anything that's a bright color(white, yellow) is more reflective. Anything that's a dark color is less reflective. You aim your camera so that it sees only the white object, you have all that brightness and the camera meter only knows lots of brightnees, not that it's white, so it picks a wrong exposure, underexposes. Your picture the white looks dull. Vice versa with something dark. The grey card is a certain shade so that you do the same thing with the grey card, it will give you the correct exposure for that particular light level you happen to be in.

When you buy a package of Delta gray cards, you will get two 8x10 cards which you can cut smaller if you want. On the back of each card is complete instructions on how to use it. Check a local camera shop, or you can order them from a place like B&H Photo.
