Eye-Fi cards have been around since 2006 as a way to wirelessly transmit your digital camera photos to your computer or mobile device. The catch was that you had to connect to a Wi-Fi network before in order to do so. Not so with the new Eye-Fi Mobi.
The new Mobi cards will let you transfer photos absolutely anywhere, since the card is its own WiFi hotspot. You just have to download a free app for iOS or Android and connect it with your card, a process that Eye-Fi claims is simple and seamless. We hope so, because the setup process for the original Eye-Fi cards was a real pain.
(UPDATE) According to the Amazon product page, the Mobi card can ONLY transfer photos to iOS / Android devices, meaning that you cannot transfer wirelessly to your computer. That is quite dumb!
(UPDATE 2) Apparently with the Eye-Fi X2 cards, you could in fact send photos directly to mobile devices. It seems as though the new Mobi cards simply streamline the process into a more user-friendly experience.
