What is the difference between TF card memory and microSD card memory?

Some android and windows tablet spec list 'TF card memory supported'. Is there a difference between 'TF card memory' and 'microSD card memory'?


Solution 1:

The microSD removable miniaturized Secure Digital flash memory cards were originally named T-Flash or TF, abbreviations of TransFlash. TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other.
