TF card, also known as microSD, is a very small flash memory card, invented by the famous storage manufacturer SanDisk company. The card is mainly used in mobile phones, but because it has the advantage of being small, it slowly began to be used in GPS devices, portable music players and some flash memory disks as the capacity increased.
SD Card is short for Secure Digital Card, which literally translates to "Secure Digital card" in Chinese. It is a brand new memory card product jointly developed by Panasonic, Toshiba and SANDISK.
