Eye-Fi today launched the 2GB Eye-Fi SD card, the production version of the wireless card first previewed late last year. The new memory is the first to build an 802.11g Wi-Fi adapter directly into the card itself and lets users transfer photos either to a local Mac or PC without having to attach a card reader or USB cable. Through a special setup process, users can not only specify a photo for automatic transfers but also send photos directly to blogs and photo websites, allowing users to post to Facebook, Flickr, and similar pages while bypassing a computer altogether.

Use of the card in a camera is transparent from a control perspective and works like traditional SD storage for any camera that accepts the format. The 2GB card is available today and sells for $100.
