Eye-Fi, the folks who make the unique SD cards with built-in Wi-Fi, are just about ready to launch the most interesting improvement they’ve made since they unveiled their first cards. Previewed in January at CES, it’s called Direct Mode, and it will let you transfer photos from a camera with an Eye-Fi card directly and wirelessly to an iPhone (or other iOS device) or an Android phone or tablet–where you can then upload them to the Web using Eye-Fi’s apps or use them with any phone app that involves photos, such as Instagram, Path, Flickr, Facebook, and Twitter.
If, like me, you do much of your photography these days with a phone but aren’t crazy about the results, this is potentially a more exciting application of Eye-Fi’s technology than its original features, which require that you be within range of an available Wi-Fi network to get photos off your camera and onto the Internet.
