Not all SD cards are created equal. While these pieces of plastic are more known for providing extra storage for digital cameras and laptops, some cards offer more. These are the so-called Wi-Fi SD cards, enabling wireless transfer from SD card to some other wirelessly connected device. And there are, in fact, two competing, ergo incompatible, brands: Eyefi and Toshiba’s FlashAir. But thanks to a licensing deal between the two, cards from one company will soon be able to work with apps and services of the other, creating one big happy Wi-Fi SD card family.
