I could never describe this device better than what their site says,

Yes, there really is Wi-Fi inside that tiny little card. We think it’s going to change the way people take, save and share photos.
The Eye-Fi Card comes with everything needed to make it simple to set up and connect to your home Wi-Fi network. After that, pop the card into your digital camera and start capturing those memories. It stores pictures like a regular SD card no matter where you are, and uploads your photos automatically as soon as you return to your home network. All you have to do is turn the camera on.
