This Micro SD card comes complete with a standard size SD adapter and a protective transparent carry case for total file protection. On its own this Micro SD card can be inserted into any device that supports the Micro size cards such as Mobile Phones and some Digital Camera. When used in conunction with the SD adapter the card can be inserted into many more devices such as larger Digital Cameras, Camcorders, SatNavs and Computers (Note: Computers without a built in card slot will require a USB card reader).
For example, many mobile phones will take a Micro SD card on its own where as many Digital Cameras and SatNavs will take the Micro SD card as long as it has been inserted into the SD adapter first.
In most cases when the Micro SD card and SD adapter are used together they can be inserted into your computer's SD card reader so that you can transfer files between your computer and camera/mobile phone/satnav. If your computer does not have an SD card reader built in you can buy USB multi card readers which will allow you to read and write to the memory card.
