The full form of TF card is TransFlash card.
TransFlash was the original name given to what is now more commonly known as a microSD card. SanDisk initially developed and marketed these tiny storage devices. While the name "TransFlash" is technically correct, the industry and consumers almost universally refer to them as microSD cards. This type of card is widely used in mobile phones, digital cameras, portable game consoles, and other small electronic devices for storing various types of data.
Essentially, a TF card is a microSD card. The name change happened as the technology became more widely adopted, and the SD Card Association took over the standardization of the format.
Here's a quick comparison:
| Feature | TransFlash (TF) Card | microSD Card |
|---|---|---|
| Original Name | Yes | No |
| Current Name | Technically Correct | Most Commonly Used |
| Developed By | SanDisk | Standardized by SD Association |
| Physical Size | Same | Same |
| Functionality | Same | Same |
So, while you might occasionally see the term "TF card," remember that it's simply an older name for the ubiquitous microSD card.
