I suspected from the beginning that the card contained some sort of embedded Linux system. If so, extending its functionality could be quite easy! But first I would need to take control of the system. I had only used the Android and iOS apps with it so far, but it was obvious that the easiest solution for interfacing with PCs would be a web app. The following thought came to my mind immediately:
"If the mobile apps are so crappy, then so must be the webapp/webserver... maybe it is full of bugs, ready to be exploited."
Boy, was I right!
Can't believe that now even WLAN enabled SD cards can be used like that.
