A TF card is virtually the same as an SD card for tablets, because the size is the same. The only difference is in functionality, such as near field communication (NFC).
The TF card, or "TransFlash," was created by SanDisk in 2004 and gradually evolved to be called the SD card. Near field communication allows other devices to read a tablet from a short distance away. However, both the TF card and the SD card are removable flash memory devices that allow users to store videos, music, photos and software on mobile devices. Over time, SD cards have gotten smaller, but the TF and microSD remain compatible due to their size.
