This is a regular-format Secure Digital (SD) card, regular in the sense that it's not of the latest SDHC (SD High Capacity) format. This is a good thing because it means this 2GB card is compatible with most SD devices like digital cameras, digital camcorders, GPS units, Pocket PCs, etc.
Unfortunately, most USB media card readers (including Sandisk's own as well as Belkin ones) cannot deal with capacity larger than 1GB yet. So be *VERY* careful if you plan to use this 2GB SD card with a USB card reader: if you do want to do it, make sure you only read from it, not write to it, or you would risk corrupting the entire memory which would require reformatting. (Unfortunately, because most OS's write some extra system information to disks all the time, it's extremely unlikely you can avoid any writes when you insert this SD card into a USB card reader.)
