I see it'd be very diffiult to question how all three worlds being "Japan" if the difference of history .could change many things like currency and culture, but this is idol anime so better ignore that part.

I think they could had talked about the system abit more since this series is about having the system connect the worlds,. The connection might also be a reason why the data of songs and stages are transferrable.

Aikatsu Pass or other ID cards are used to identify idols, not for data transfer tho.
