Switch 2 Game-Key Cards are physical cards that only contain a key to download your chosen game. That means there’s no actual game data on the card you insert into your Switch 2

The new Virtual Game Card system that Nintendo just added to the Switch includes a privacy-focused feature that's easy to miss.

The Nintendo Switch just got a new update that adds Virtual Game Cards as a way to share digital games with other people. But the update also closes a loophole that would let you play shared games online at the same time as somebody you were sharing the game with, as reported by Eurogamer.
