An SD card reader is a small, portable device that lets you access the data stored on an SD card. This tiny memory card is used to expand storage on various devices, including cameras, smartphones, drones, and action cameras. Think of an SD card reader as a bridge between your device and your computer.
How Does an SD Card Reader Work?
To use an SD card reader, you simply insert the SD card into the reader. Then, you connect the reader to your computer using a USB cable. Once connected, your computer recognizes the card as an external drive. You can then copy, move, or delete files from the card just like any other external storage device.
