What is a microSD card?
MicroSD ("microSD") is a format for removable flash memory cards. SD is an abbreviation of Secure Digital. MicroSD cards are commonly used in cellular phones, as well as in some newer handheld GPS devices, portable media players, digital audio players, expandable USB flash memory drives, Nintendo DS flashcards, and digital cameras. 

The microSD format was originally created by SanDisk. It was originally called T-Flash, and then TransFlash, before being renamed microSD when adopted by the SD Card Association (SDA). Other flash card formats approved by the SDA include miniSD and SD card.
