When sending a virtual game card from one Switch to another, the user needs to know immediately whether it’s successful (screenshot above). The regular Switch notifications are queue-based and asynchronous (img 1 below), therefore a new type of notification with persistent connection is created to provide synchronous responses (img 2).


To make swapping virtual game cards easier to manage, the model, shape, and color of each console and controller is drawn on the screen (screenshot above and img 1 below) to distinguish different units. This information is saved (img 2) on the same persistent connection server mentioned above.
