Internal card readers are devices installed in the computer case that allow you to read and write to different types of memory cards, such as SD, microSD and CompactFlash cards. They can be multi-card readers that support multiple card types or specialised readers for specific card types. Often they also have additional features such as extra USB ports and fast data transfer speeds. Internal card readers offer a neat and integrated solution, making them ideal for computer enthusiasts, photographers and videographers who want a convenient and permanent way to transfer files from memory cards directly to their computer.
