This 1GB SanDisk miniSD memory card offers all of the benefits of a standard SD card in a much smaller size. In fact, it is over 60% smaller than a full-sized SD card. The SanDisk miniSD cards are used to store digital images, video, MP3 files and other data in mobile phones. Built-in security features enable users to download, store and play secure content. The SanDisk miniSD card includes an adapter that converts the miniSD card into a full size SD card to be used with the growing number of SD-compatible devices available in the market.
