If you wonder what is a tf card, then TF card stands for TransFlash Card more commonly known as a Micro-SD card. It is a very small card, even the smallest memory card available right now. It’s actually four times smaller than the regular SD cartor and is around the size of a pinkie finger. This card uses the latest NAND MLC technology as well as the controller technology from SanDisk.

These cards are mostly used in mobile phones and can also be used for a variety of other electronic devices. Their small size is also making them very popular to be used in flash memory disks, GPS devices, portable music players and surveillance cameras.
