Does the Iron Bank issue note/paper currency to clients? Surely they arent still loading up boats with the literal amount of gold that they lend out?? Or are they?

Hello, new here. My favorite part of i&f is the religions but I've only read the main novels. My question is of the other canon material, how does it deal with the religions in comparison to the main novels? About the same? Less? More? Is there any that gives a much more "insider" view of one or more of the religions? Think Arya with the Faceless Men as a bar.
