As unearthed by GameSpot, Nintendo account information will be provided to the publishing giant for users to establish an Origin account.
Information to be transferred to EA includes e-mail addresses, Nintendo Network ID, friend list, country, language, date of birth and Mii information.
The new policy states however that personal details obtained does not include credit card or other financial account information.
Similar polices are also in place for PS3 and Xbox Live users.
The scheme is likely to be used to gather analytics data on online user behaviour in EA-published games.
EA’s Origin digital distribution platform, which is also available on PC, Mac, iOS and Android, currently has more than 21 million registered users.
