The first card using the SD association's Wireless LAN standard is Toshiba's FlashAir and we've just spent some time with it here at CES. It's much like Eye-Fi's Direct Mode insofar that it also can sling pics to devices over WiFi from a diminutive SD card, but instead of requiring pairing and an app download the FlashAir requires just a browser. The 8GB class six card broadcasts an 802.11b/g/n hotspot, replete with its own web server onboard, which means its contents -- like say pictures you've previously snapped in your camera -- can be accessed in a browser by any connected device.
Despite some false starts (CES is where WiFi networks go to die...) pictures from a point and shoot appeared as quickly as we could refresh http://flashair/ -- the address from where one accesses its contents. Once there, you can browse individual folders, splaying pics (and we'll assume other contents) for your perusal. As previously planned, it'll start shipping in February at around $70 and we were told more capacious units will follow at a later date. Video demo of the tech awaits in the video after the break.
