What is card reader used for?

A card reader is an electronic device used to read storage media (such as SD cards, MiniSD cards, SmartMedia cards, memory sticks, etc.) stored on digital media (such as cards, disks, memory sticks, etc.). They are usually connected to a USB port on a computer or other device, allowing users to easily insert storage media into a card reader and then copy data from the storage media to a computer or other device.

Card readers are widely used in digital photography, music creation, videography, media production and other fields because they help users store and transfer data easily. In addition, many smartphones and tablets are equipped with card readers so that users can easily copy data from storage media to the device.
