The (TransFLash card), sometimes known as the Micro SD card, was developed in collaboration between Motorola and SANDISK and introduced in 2004.
Micro SD and TF Cards can be used to store data such as films and images in a number of devices, including smartphones, cameras, laptops, and other similar devices. Because it is ultra-small (11x15x1mm) and only a fifth of the size of an SD card, the TF card is known as the smallest memory card. It's about the size of a fingernail for comparison reasons.
The SD Association called the TF card Micro SD after it adopted the SD structure. This happened at the end of 2004 to integrate it into the SD product line.
The SD card (Secure Digital Card) was introduced by Panasonic, Toshiba, and SanDisk in August 1999, a year before the TF card. It's a new sort of memory that uses semiconductor flash memory as its foundation.
The SD card is widely used in portable devices including digital cameras, personal digital assistants, multimedia players, and other similar products. This is owing to its small size, fast data transmission speed, hot swappable capabilities, and other praiseworthy features.

A TF card is a small flash memory card that incorporates SanDisk's latest NAND MLC and controller technologies.Micro SD cards can operate in SDIO mode, which allows them to perform non-memory functions such as Bluetooth, GPS, and Near Field Communication. On the other hand, a TransFlash card is incapable of doing such functions.
