Hey everyone,
I'm new to the forum, so, please be nice.

My question is this: if I receive a Nintendo eShop card for Christmas and redeem it on my Wii U, will I be able to access the
same credit on eShop on my 3DS? In other words, is the credit cross-compatible between the eShop on the Wii U and 3DS if both are utilizing the same NNID?
Thanks,
