For digital photographers, especially professional ones, the SD cards in cameras aren't enough to catch up with their shutter-happy fingers. But while all digital cameras worth their salt have such card slots, not all of them feature Wi-Fi for convenient transferring to computers with more ample storage. Eye-Fi provided a bridge with their ingenious Wi-Fi SD cards. But starting September 16 this year, majority of those cards sold before 2015 will become useless pieces of plastic and silicon. All because Eye-Fi is shutting down servers and services that those cards need in order to function.
