SD refers to the Secure Digital memory card, a particular type of removable flash memory chip for use in small appliances to either add memory or provide a portable memory function. It features a sliding switch that can lock the card and prevent data from being erased or written.

SD cards are rapidly becoming the standard, along with MicroSD, which is a much smaller card that is used primarily in smart phones, but can also be used in an adapter. A third SD card, the Mini-SD, has not caught on to the extent of the Micro. One needs to be careful when purchasing the smaller cards to be sure the right one is selected, as they look much alike.
