Guild cards

Hi, i am wondering about the guild cards and how i can go about getting some? i dont know much about the system and was wondering if any high rank hunters could help me out since i believe the higher the rank the better the results are? Not sure about this but i am curious for more info since i play alot offline. thanks

Go here for info, basically when you play with others a menu option is available to share your card. Others can do the same and then you have theirs. On the wii u it is on the gamepad at the top.
