Announced for the first time by SanDisk Corporation at CeBIT 2003, the miniSD joined the Memory Stick Duo and xD-Picture Card at this small form factor.

The miniSD card was adopted in 2003 by the SD Association as an ultra-small form factor extension to the SD card standard. While the new cards were designed especially for use in mobile phones, they are packaged with a miniSD adapter which enables compatibility with all devices equipped with a standard SD Memory Card slot.

MiniSD cards are made by several different manufactuers and come in different brand names. Their compatibility is universal.
