Normally, there would be a 8M, 16M or 32M SD card followed with the digital camera.
You may check with the box or the instruction manual/ specification. There would be a list to identify the component or parts within the box.
For the 1 GB or 2 GB card, it would be the free gift from the shop or the company like Panasonic or Canon. Sometime there would be a special promotion together with additional battery or camera bag etc.
