SD Plus

SD Plus is a type of Secure Digital (SD) card developed by SanDisk that offers extra connectivity features over a traditional SD card. Specifically, SD Plus cards can connect directly to a USB port, which is useful for transfering content stored on the card from a digital camera or similar device. The card was built with the design of the Reduced-Sized MultiMediaCard (RS-MMC) as inspiration. When the card is in normal use, it is in its normal SD card mode, but when it is folded (literally) it produces the shape of a USB connector.
