5.Different application

SD cards are widely used in portable devices, such as digital cameras, personal digital assistants (PDA) and multimedia players.

TF cards are mainly used in mobile phones, but because of its extremely small size, with increasing capacity, TF cards have gradually begun to be used in GPS devices, portable music players and some flash memory disks.

6.TF card can be converted to SD card
