High storage capacity SD cards have been on the rise, but a SD card that is capable of data transfer via Wi-Fi? That's what the Eye-Fi is, a Wi-Fi enabled SD card that allows a full transfer of all existing data on the SD card onto a online photo site such as Flickr for moments when you require more space for a longer photo shoot. Unfortunately, you will be transferring the files in its original size, with foreseeable long uploading times.

engadget.com - You may have seen the Eye-Fi, launched this week, nearly a year and a half since we first heard about it. If you're just catching up on the news, it's basically a WiFi-enabled SD card (and accompanying web service) used to transparently and wirelessly transfer photos from your camera to your computer and/or a variety of photo sharing sites. Sounds like a great idea in theory, it turns out that the Eye-Fi is, in its current release, an answer seeking a question.
