/*
 * card_controller.h
 *
 * Description:
 * The controller is serving the cards (devices) by providing them means
 * to register to the controller with their SM and giving each a unique id for communication.
 *
 * regCard() is used for card registration.
 * run() is used for running the controller, usually in it's own task in an endless loop,
 * blocking on recv messages.
