flash memory cards

If your camera uses a removable flash memory card such as Secure Digital (SD) or CompactFlash, consider plugging a memory card reader into your computer. When you insert your memory card into the reader, you can copy your pictures from the memory card to your computer without draining your camera’s battery, dealing with connection cables, or installing additional software. Some computers and laptops have a built-in memory card reader. Check the documentation for your computer to determine if your computer has one.
