What is a TF Card? All You Need to know About

What is a TF card
By Gopal Sengar Updated

The TransFlash cards, also called as TF card was introduced by SanDisk Corporation in the year 2004 as the world’s smallest memory cards, almost equivalent to the size of a fingernail. These were solely made to fit into the mobile phones as a means of secondary/external storage space.

Many users confuse these with the SD cards which are otherwise different from traditional TF cards. Here in this article, we are going to have a detailed discussion on what these TF cards do and what are the differences between SD and TF cards. So without wasting any more time, let’s just directly enjoy the ride.

So here we GO.

Why are these TF cards used?

TF and SD cards do the same function of imparting an external storage space to the device/system. You can store thousands of media files and other necessary data on these cards. Simply insert this card in your phone and enjoy storing all the relevant data that you wish to and want ever since you bought your handset. It was designed for being used in digital cameras, iPod, PDA, and smartphones.

Are TF and microSD the same thing?

Yes, these two cards are same but they have a lot of technological differences. Both types of cards are compatible with each other. Moreover, the microSD bears exactly the same dimensions as that of TF cards and serves the same function of providing an external storage to the device.

What are the differences between a microSD and a TF card?

Difference 1: Dimensions are different

SD card’s dimensions: 24mm x 32mm x 2.1mm
TF card’s dimensions: 15mm x 11mm x 1mm

Difference 2: Designations vary

A TF card is one of the memory card known as Micro SD but the name was thereafter changed to TransFlash. This happened because the SD franchise was then purchased by SDA institution along with miniSD and the SD card. SD stands for Secure Digital, so these cards are known as Secure Digital Memory cards in common.

Difference3: On the basis of Origin

An SD card is an upgraded memory card which is based on the semiconductor flash memory device.
TransFlash, on the other hand, is a tiny flash memory storage card which relies upon NAND MLC and other controlling technologies from SanDisk. This creates a very fine line between the two.

Difference 4: Establishing Connections

An SD card can be inserted into systems via an adapter but the TF cards are transmitted into the MiniSD.

Difference 5: Non-memory functions

MicroSD cards can perform non-memory functions like Bluetooth, Near Field Communication, GPS, etc. but the TransFlash cards are unable to do all this.
Also, you’ll find a security section switch on SD cards but not on TF cards. The variants in the two categories are like as:

SD cards: 128Mb, 256Mb, 512Mb, 1Gb, 2Gb, 4Gb, 6Gb, 8Gb, 16Gb and 32gb.
TF Cards: 128Mb, 256mb, 512mb, 1Gb, 2Gb, 4Gb, 6Gb, 8Gb, 16Gb, 32Gb and 64Gb.

Difference 6: Functionality

SD cards have their application in portable pieces of equipment like Digital cameras, media player, etc.
TransFlash cards, on the other hand, are used for mobile phones only. It applies to the devices for GPS, media player and other Flash memory drive functionality.

How TransFlash got changed into SDcard?

SD card Association in 2005 adopted the TransFlash after which the TF cards started being known as the microSD cards.

Final Words:

So this was all about the TF cards and how these are different from today’s microSD cards. Although both are same, it’s just that the latter was once a TF card. Only the change in names has been incorporated into the organization which purchased it in the year 2005. All the differences have also been discussed above.
