Switch 2 Game-Key Cards Hold a Key, Not the Game

A Switch 2 game-key card is a physical card that holds a key to download the game, not the game itself. To play one you need an internet connection and free storage for the first download and launch, a console on system version 20.1.1 or later, and the card in the slot whenever you play.

Nintendo’s wording is plain: game-key cards “don’t contain the full game data. Instead, the game-key card is your “key” to downloading the full game to your system via the internet.” Once the game has downloaded and launched once, it starts without a connection.

Game card, game-key card or digital: the differences

Nintendo describes three ways a Switch 2 game arrives. This is how they compare, in Nintendo’s own terms.

	Regular game card	Game-key card	Digital (eShop or download code)
What is on the cartridge	The game data	A key; not the full game data	No cartridge; a virtual game card on your account
Download needed	No: the data is on the card	Yes, the full game, over the internet	Yes
Where the game lives	On the card	System memory or a microSD Express card	System memory or a microSD Express card
Card needed to play	Yes	Yes, inserted every time	No; the virtual card is loaded on the console
Internet after setup	Not for the game data	Not after the first launch	Not once the virtual card is loaded on the console
Lending	Hand it to family or friends	Hand it to anyone; it downloads on their console	Certain games, to family group members, for 14 days
Tied to a Nintendo Account	Not stated	No	Yes, the account used to buy or redeem it

Nintendo’s pages do not cover reselling any of the three, so the table leaves it out.

What you need the first time

The overview lists three steps: insert the card, download the game, play. For the download, Nintendo says “an internet connection and enough free space in your Nintendo Switch 2 system memory or microSD Express card are required.”

• Space. “The amount of free space required is indicated on the game-key card packaging,” and it is also shown on the Nintendo Store or eShop page for the game’s digital version. Nintendo’s data FAQ says Switch 2 has 256 GB of storage, part of it reserved for the system. More space means a microSD Express card, the card type the overview names; our microSD card guide covers which cards Switch 2 takes.
• System version. “Your Nintendo Switch 2 system must be updated to version 20.1.1 or higher.”
• No account step. “A Nintendo Account is not required to download the game data.”

Save data is kept in the console’s system memory whatever form the game takes, Nintendo’s data FAQ says, and it stays there if you delete the downloaded game to free space.

After that: offline, with the card in

After the first launch, the game starts without an internet connection. Nintendo’s sentence in full: “An internet connection is only required when you launch the game for the first time. After this, the game can be started even without an internet connection. However, like regular physical software, the game-key card must be inserted into the system in order to play the game.”

That is the practical difference from a digital game. A digital game, which Nintendo calls a virtual game card, plays offline once it is loaded on the console and needs no cartridge. A game-key card behaves like a cartridge for starting the game, but its data lives on the console like a download.

Lending, and playing on another console

Nintendo says game-key cards are not tied to a Nintendo Account. “That means you can lend a game-key card to whomever you want by handing it to them. Once your friend inserts the game-key card into their system, the game data will download (just like it did for you).” The friend needs the same things you did: internet, free space and a current system version.

Digital games are narrower. Nintendo ties them to the Nintendo Account used to buy or redeem them, loads them on up to two linked consoles, and lends them only to members of your family group, for 14 days at a time. Our guide to sharing games with family sets out those rules beside Steam’s, Xbox’s and PlayStation’s.

Giving a boxed Switch 2 game as a gift

A game-key card is a real box to wrap, and it does not need your Nintendo Account or theirs to download. Check the case first: Nintendo says you can tell a game-key card “by looking at the label towards the bottom half of its case.”

If it is one, the person opening it will need a Switch 2 updated to 20.1.1 or later, an internet connection for the first download and launch, and the free space printed on the box. If their console is short of storage, a microSD Express card is the add-on Nintendo names.

If you would rather give the digital version, the options change soon. Nintendo announced on 9 November that from 16 November the eShop will let family group members “gift digital games to other members of their group”, on system version 23.5.0 or greater. It says some products will not be eligible, supervised accounts cannot send gifts, and the number of gift purchases in a period is limited.

Questions people ask

What is a game-key card on Switch 2?

A physical card in a game case that holds a key, not the game. Nintendo says game-key cards “don’t contain the full game data”; inserting one starts a download of the full game to your console, and you then play with the card in the slot.

Do you need internet for a Switch 2 game-key card?

Only at the start. Nintendo says the download needs an internet connection and that internet “is only required when you launch the game for the first time.” After that the game starts offline, as long as the card is inserted.

Do you need the game-key card in the console to play?

Yes. Nintendo says that, like regular physical software, “the game-key card must be inserted into the system in order to play the game,” even though the game itself is stored on the console or microSD Express card.

How much storage does a game-key card need?

It varies by game. Nintendo prints the free space needed on the game-key card packaging, and lists it on the Nintendo Store or eShop page for the digital version. The game goes into system memory or onto a microSD Express card.

Can you lend or share a game-key card?

Yes. Nintendo says game-key cards are not tied to a Nintendo Account, so you can lend one to anyone by handing it over. The game downloads on their console when they insert it. Nintendo’s pages do not mention reselling.

How can you tell if a Switch 2 game is a game-key card?

Look at the case. Nintendo says you can tell “by looking at the label towards the bottom half of its case.” Some Switch 2 games use game-key cards and others regular game cards, so check each box.

Do you need a Nintendo Account to use a game-key card?

Not for the download. Nintendo’s overview says “A Nintendo Account is not required to download the game data.” The console does need system version 20.1.1 or higher to play a game-key card.
