The Eye-Fi card is a unique 2GB SD memory card for digital cameras. What makes it unique is that it can upload photos to your computer and/or your favorite online photo sharing/social networking site wirelessly and without any effort on your part.

Note: I don't do Windows. So while the product is supposed to work roughly the same way on a Windows box, I can't tell you anything about how it works on a PC. This review describes using the Eye-Fi card with a Mac.

Setup is simple. Just connect the included SD card reader to a USB port on your Mac (or PC), insert the Eye-Fi card, and install the Eye-Fi Manager software, which adds a menu item as shown below and runs as a faceless background application on the Mac.

Choosing Open Eye-Fi Manager from the menu opens the Eye-Fi Manager Web page(s) in your default browser as shown below.

All configuration is done via these Web pages. You can specify where on your Mac you want your photo files to be sent automatically (i.e. iPhoto or any folder on your Mac), which Web site(s) your photo files should be uploaded to automatically, and which wireless network(s) the Eye-Fi card should use to send the photo files to your Mac and/or the Web. You can also see a listing of photos that have been uploaded to the Web (Upload History), name or rename the Eye-Fi card, change your password, and enable/disable auto-start for the Eye-Fi Manager background application.

After configuration the magic happens... just insert the card in your camera and shoot some pictures. Without doing anything further, the pictures are automatically copied to your Mac (into iPhoto or to any folder) and/or uploaded to your favorite photo-sharing Web site. There's even a cool little animation displayed in the upper right corner of your screen so you can watch as your pictures magically arrive on your hard disk as shown here.

Which sites are supported? Glad you asked. You can have your photos automatically uploaded to: Bluestring, Costco, Dotphoto, Facebook, Flickr, Fotki, Gallery, Kodak Gallery, Nikon My Picturetown, Phanfare, Photobucket, Photoshop Express, Picasa, Ritzpix, Sharpcast, Shutterfly, Smugmug, Snapfish, Typepad, Vox, Wal Mart, Webshots, and Windows Live.

The Bottom Line

The Eye-Fi Manager software is easy to install and configure and the Eye-Fi card transfers photos to your Mac and/or your favorite Web site with no further effort on your part. If that appeals to you and you don't mind paying the huge premium (standard 2GB SD memory cards can be found for under $20), you'll love this product.
