It is one of the smallest removable flash memory card formats designed specifically for small devices. Some of thse devices include: mobile phones, handheld GPS devices, portable audio players, flashcards for Nintendo DS emulation, and expandable USB flash memory drives. MicroSD cards can be used in SD-compatible devices via an SD adapter.
