To transfer data from an SD card to your PC, you will need an SD card reader. This is a device that plugs into your computer’s USB port and allows you to read the contents of the SD card. Most modern computers have built-in SD card readers, but if yours doesn’t, you can purchase an external reader relatively inexpensively.
Once you have a card reader, simply insert the SD card into the reader and plug it into your computer. Your computer should recognize the SD card as a removable storage device and allow you to view and copy its contents. From there, you can select the files you want to transfer and copy them to your computer’s hard drive or another storage device.
