Expresscard cards are about 1" by 3" by 1/8" or roughly the same size as PC Cards, but with a smaller rectangle "cut out" of it to form a fat "L" shape. The cards are plugged into (unlike USB devices, they usually don't stick out except for antennas and other attachments) the PC Card slot on laptops, usually to add features that the laptop doesn't already have.
