Nintendo ID requires credit card verification for minors
Parents looking to create additional Nintendo ID accounts for their children are required to pay a one-time $0.50 fee via credit card to provide consent for minors to access Nintendo Network.

Nintendo's confirmation email notes that Wii U owners can use a "Parental Control PIN" to create additional Nintendo Network IDs without any added charges. Credit card information used for the transaction doesn't appear to be stored on the system.
