The Nintendo Switch 2 has caused some controversy since its release, and the "game key fob" is undoubtedly one of the most heated topics.Despite clear opposition from some of its player base, Nintendo shows no signs of abandoning the format.The company is currently actively promoting this concept to players.

To this end, Nintendo released a new official explanation video today, explaining in detail the purpose and working method of the game key fob, aiming to eliminate all doubts among players.

Detailed video:

According to the video, there are two types of physical game cards for Switch 2: standard game cards and "game key cards" with specific key identification.The logo will also be printed on the front of the game packaging.

Unlike standard cartridges, which contain complete game data, the Game Key Card itself does not store any game data.Its function is more like a "key".After inserting the key fob into the console, players need to connect to the Internet to obtain complete game data.Before purchasing, players need to ensure that there is enough space in the host memory. The required capacity will be marked on the package.

When you insert the key fob for the first time, you will be prompted to start the game.After this initial completion, players can play the game at any time as long as the key fob is placed in the card slot.When switching games, the operation is no different from a standard cartridge.In addition, this key card can also be inserted into another Switch2 console and can be played after going through the same process and verification.
