I know that the Xbox portal is unique and is not cross platform, and I know that the 3DS one is universal and is cross platform with all other platforms except xbox BUT I can't find this anywhere:
What portals FROM OTHER PLATFORMS are compatible with the 3DS? Will the Wii/Wii U/PS3/PS4 portals work with 3DS?
