Realtek USB Card Reader is a driver package that allows Windows to properly recognize and use USB card readers built on Realtek chipsets. Once installed, your PC can read and write to popular memory card formats—such as SD, SDHC, SDXC, and, depending on the hardware, MMC—through built-in laptop readers or external USB devices. The driver enables reliable hot-plug detection, correct power management, and stable data transfers, ensuring the reader appears as removable storage in File Explorer. It is often preinstalled by PC manufacturers, but installing or updating it can fix recognition issues, missing drive letters, or slow performance with Realtek-based card readers.
