Secure Digital memory cards are among the most common storage devices for small electronics, such as digital cameras and PDAs. An SD card stores a great deal of information in a small package about the size of a postage stamp. However, many mobile phones use an even smaller type of storage card called MicroSD. MicroSD cards are pin-compatible with standard SD cards. However, you cannot put a MicroSD card in your SD card reader. To transfer data to and from a MicroSD card on your computer, use a MicroSD card adapter. Writer Bio
