What Are Micro SD Cards For?
A micro SD card is a removable flash memory card which can be used in a variety of electronic gadgets. They are commonly used in digital cameras, mobile phones, portable media players and Nintendo SD flash carts.
There is a variety of SD memory cards including SanDisk, Transcend and Samsung memory cards and these all come in a variety of memory sizes ranging from 2GB onwards, up to anything as large as 32GB.
Commercially, the SD mobile memory is the smallest available with dimensions of just 15mm x 11mm x 1mm (this is about a quarter of the size of a standard SD card). You can find adapters that will enable a micro SD card to be used with devices that are intended for SD, mini-SD, Memory Stick Duo and USB cards however these are not universally compatible.
The SD mobile memory is the same as the TransFlash card and both can be used in devices meant for each other with the only difference being, that the micro SDHC card adds support for SDIO mode which enable non-memory cards like Bluetooth, GPS, and Near Field Communication devices to work.
Both TransFlash and the micro mobile memory card are the same because the format of the mobile memory was originally created by SanDisk who called it T-Flash, which then became TransFlash. Finally the memory card was re-named micro SD when it was adopted by the SD Card Association.
If you’re looking for a micro SD card, it is important not to get mixed up with the newer micro SDHC card. Both these cards have a similar format but the SDHC card is not compatible with all devices intended for micro SD card. If you are unsure about the type of card you need then check up on the internet- some websites that sell these cards will give a brief description of what they do and some may also list the types of device they are compatible with.

You can also rely on a warranty that will be supplied by some online retailers if you buy with them, so you don’t have to worry about the card not working and being unprotected because you bought it online.
