We came across this cool little SD card the other day. It's an memory card for the digital camera with a built in wifi. This means that you can upload your pictures computer without ever having to use a cable to connect the two. Some digital cameras have wifi built into them but a lot of them don't. With a Eye-fi card it doesn't matter, the SD card makes the wireless connection for you.
For a small additional cost, you can also use the Eye-fi card to upload pictures directly to your favorite photo sharing site such as MobileMe, Facebook or Flickr.
