Eye- Fi connected.
Basically the camera will know it is a Eye-Fi card and not a standard card. Depending on camera, it will open a few settings like wifi on/off (to save on battery) and maybe other things.
The most I really get into it is, I get an icon to know to know it is uploading to my pics, lol.
