Bank transfers?

[Navi]

For bank accounts a number is convenient. Having that bank account tied to your mailbox number is also convenient because they already use it to collect riln on delivery. Numbers being used in place of names also makes sense because Shadgard is a pioneer town, but there are many people coming in and leaving. They can't remember everyone's faces. I imagine they assign a number, and whenever you go up they ask for your number and if you want to transfer money they take it and transfer it. We're not asking for people to be granted access to your vaults. You're just receiving riln. So no security is really required. Who's going to say no to free riln. Right? Logical.
