This XP Bank is a large building with ALL RELATIVE COORDINATES, therefor, you can copy the entire building (as long as the building is facing the same direction) in MCEdit or another world editor, and copy it into a survival world with your friend(s).
This bank allows at most 4 people to create their own accounts, and their own pin numbers, to access their account. As of now, there is no Automatic way to reset accounts. To reset accounts: break all of the repeating command block pillars behind the first dial pad. Next, break the sand block behind the account creating section and set it back to the top of the piston slide. Next, delete every item in the chests behind the XP deposit/withdrawal. You can only reset all of the accounts in creative, so if you plan on doing this; enable cheats on the world you copied it into.
