You’ve probably heard of Realtek – There’s a good chance this company made your computer’s sound card or WiFi adaptor. However, seeing an application you don’t remember installing when you look through the programs list is always a little worrying: just what is Realtek Card Reader software, and do you even need it?

Card Readers

Basically, this software is designed to allow Realtek-branded card readers to function. What’s a card reader? That’s easy: it’s any piece of hardware that can read data from an SD card. In a way, your cell phone is a card reader. You may also notice that your laptop has a card slot, like in the image below.

Most commonly, though, you’ll see small, USB-powered card readers. These are usually made to accept either standard SD or MicroSD cards, although more expensive models might be able to handle both.

Why Use a Card Reader?

From a technical point of view, there’s really no advantage to using a card reader instead of a USB thumb drive. That said, some devices only accept SD card inputs and in those situations, a USB stick just won’t do. There’s also the smaller form factor: you can transfer gigabytes of data to a MicroSD card, and these are tiny enough to fit into your wallet’s change pocket. Just be sure not to lose it!

Do I Need the Card Reader Software?

If you’ve just bought a new laptop or PC, though, and the card reader application is already installed, feel free to delete it. It can always be reinstalled later if needed.
