It's unclear to me in your comment if you know this so just want to point out that with Switch 2 a lot of the cards are just licenses for a digital download - particularly 3rd party games. 1st party though it looks like they're (currently) putting the whole game on the cards.

Given their obsession with piracy/emulation I wouldn't be surprised to see them completely abandon it in the future and just have the cards be license keys like Sony/M$ currently do. We'll see i suppose.
