Easy Sharing with Game Cards
Those that have managed to ruin an optical disc or two will appreciate Nintendo’s decision to make physical games cartridges for Switch. Called Game Cards, these tiny chips are no bigger than a full-size SD card from a camera. Nintendo treats every Game Card with a coating to make it taste bad so that younger players don't attempt to swallow them.
The Nintendo Switch Game Cards are the only way that you share your games with anyone else easily. Buying digital binds the game to your Nintendo Account. Only a single Nintendo Switch can be paired with a Nintendo Account at any given time.
