When people talk about the Grey Card, they're usually referring to the KODAK Grey Card, which is another relatively simple but very accurate method of exposure determination. This is done by taking a spot meter reading from the card, which has an 18%(17.68% precisely) value to work from. This value is a logarithmic average value between pure white (100% reflectance) and pure black (0% reflectance).
It is a good method to determine exposure, and it's really cheap. I would suggest you buy one, read the instructions carefully (and follow them). You'll be happy with the results.

Joe does your camera meter have a spot meter?

i have a nikon n65, it says it only has 3D matrix metering and centerweighted metering, the centerweighted is only in manual mode, so im thinking that it doesnt have spot metering.

Regardless of the type of metering your camera has, to use a grey card you can place the grey card anywhere that the light is the same as your subject. Fill the frame with the grey card (even if you have to move the camera and get real close). Don't block the sun with your camera or body. Meter the grey card and set the exposure. Then recompose and shoot. It's that easy.
Remember that you don't ALWAYS want the exposure to be set to the grey card value. Visualize the tones you want to expose and adjust exposure accordingly.

Keep in mind that if you meter off the palm of your hand (which for most people is lighter than a desired midtone) you generally need to open up a stop, otherwise you'll be underexposing.
