It is like out of a James Bond movie, a wireless SD card that sends your pictures to your computer at home! It’s much faster than emailing pictures from your cell phone. All Eye-Fi Cards come with everything needed to set up and connect to your home Wi-Fi network, then insert the card into your digital camera and start capturing memories. It stores pictures like a regular SD card and as soon as you come into your wireless network your camera automatically downloads your pictures onto your computer at home. Eye-Fi Card works with 802.11g, 802.11b and backwards-compatible 802.11n wireless networks Eye-Fi software works with Windows XP, Windows Vista, Mac OS X (10.4 and 10.5) Eye-Fi software works with Internet Explorer 6 and 7 (Windows only), Firefox 2.0 (Windows and OS X) and Safari 3 ( OS X 10.4 -10.5) Eye-Fi card requires an Internet connection for setup and a wireless router with DHCP enabled for wireless transfers Eye-Fi Card works with virtually all digital cameras that accept SD memory cards. Here is a list of compatible >cameras Easy download is not the only feature, it also has crime fighting features! A lady who was vacationing in Florida was devastated when her camera bag was stolen from a restaurant when she accidentally left it behind. When she got home she not only received her vacation pictures but also the pictures of the thieves who actually worked at the restaurant! While the SD cards run about $100.00 a piece, as a photographer myself I can appreciate being able to download my pictures from a shoot location to my computer at home. It could mean not carrying extra SD cards, providing unlimited picture taking. Not to mention that if stolen my camera could eventually find its way back home.
