There are many types of memory cards used by modern digital devices. There are so many that it can become confusing. Cameras use SD cards and phones use TF cards. But gamers will want to remember that many portable game devices use MS memory cards. If you need even higher capacity to store lots of data, look for the MS memory card duo units. These can store twice as much as standard units. If you have an old memory card, you may be able to use it in your gaming device by getting an MS memory card adapter. This will let you insert a different type of card into it.
