Summary: The card has it's own wifi access point. If there is a known access point, the card can be instructed to use it. There's no way to unset it without access to a desktop/laptop. If there's no access point available, the card will take over the role. There's a delay when taking a picture and the card uploading, about 15-20 seconds. During this period, the camera must be left on. Before taking a shot, the receiving app must be up and running.
