The SD (Secure Digital) format was developed by SD Association for use in portable electronic devices. Introduced in 1999 by a joint collaboration among SanDisk, Panasonic, and Toshiba, the SD card soon found its way into a vast array of electronic devices and quickly became the industry standard.  As the electronic landscape changed over the years, so did the SD card.  It got progressively smaller, with the miniSD and microSD coming out in the following decade.    Read Also: Yamaha announced the launch of TW-E3B and TW-E5B TWS earbuds in India   What is the difference between a microSD and a TF Card?

There is practically no difference between a microSD and a TF Card. The TF card was jointly developed by SanDisk and Motorola and was launched on the market in 2004. With dimensions of 11x15x1mm it was considerably smaller than the SD card.  Originally called the TransFlash card, TF could easily work with devices that accepted an SD card. All that was needed was a handy, portable that the TF could be fitted into. The SD Association later incorporated the TF card into its range of formats and rebranded it as the microSD card. Functionally, there is no difference between a TF and a microSD card. They can be used interchangeably in any device that accepts them.
