The MicroSD card is a very small flash card that is mainly used in mobile phones, but because of its small size and increasing storage capacity, it has been used in GPS devices, portable music players and some storage disks. Its size is 15mm x 11mm x1mm, which is almost equal to the size of the finger. It is a compact flash card. It can also be used in the SD card slot via an SD adapter.
