Why are SD Card Readers needed?

Because of it’s widespread use, it has become desirable to include SD card readers in newer computer systems to facilitate easier data transfer from device to device.

A common task that a user would face would be copying their media from their digital camera to their pc. In the past, this meant that the user would have to install the camera’s software and drivers on the pc, then connect a cable from the camera to the pc to access the media.

This process changes when a sd card reader is built in or connected to a computer, the user simply removes the sd card from the digital camera and inserts it into the sd card reader, where the media is immediately accessible as using any other portable secondary storage device.
