The “SD” initials in SD card stands for Secure Digital. It is a kind of non-volatile memory card that is designed to be used on portable devices like for example in GPS navigation gadgets, mobile handsets, digital cameras as well as tablet computers. This kind of memory card format or Secure Digital standard was initiated in 1999 as an evolutionary improvement over MMCs or MultiMediaCards.

This standard is maintained by the SDA or the SD Card Association. SD technologies have been employed to more than 400 brands over dozens of product types especially in more than 8,000 models.

The SD format is divided into 4 different types and they are SDSC or the Secure Digital Standard-Capacity, SDHC or the Secure Digital High-Capacity, SDXC or the Secure Digital eXtended-Capacity, and the SDIO or the Secure Digital Input/Output which merges the data storage with that of the input and output functions.
