Pokémon Bank is a Nintendo 3DS application that allows players to store their Pokémon on the Internet from Pokémon Black and White, Pokémon Black and White Versions 2, and Pokémon X and Y, similar to the storage games Pokémon Box Ruby and Sapphire and My Pokémon Ranch. There is a total of 100 boxes available that could store up to 3,000 Pokémon. This software costs an annual fee of $4.99. Downloading this app comes with a free app called Poké Transporter an app to transfer previous generation Pokémon. If you run out of membership, and do not take your Pokémon out of your Bank, they will be sweeped (deleted) out of the server and will disappear forever. Nintendo advises the players to purchase a new membership "as quickly as possible". A legitimacy checker has been added to the application
