Micro SD

Many devices these days use micro SD slots as a form of memory. These miniature cards come in sizes up to 8GBs and they can be used in cell phones, cameras, and even converted into other devices such as a standard SD or a Memory Stick Pro Duo. Because they're so flexible, these cards are a great way to pass pictures and documents around between family and friends, without having to worry about printing them out or burning them to a CD.
