Why use the word LARP?
The interface supports an acted-out scenario: a fictional customer, business, transaction or financial story. “LARP bank” is informal shorthand for that simulated environment.
Professional productions may instead call the same thing a fictional banking interface, prop banking app or banking-screen simulator.
What can a LARP bank show?
Common scenes include account summaries, recent transactions, cards, savings goals and transfer screens. These details help tell a financial story without using a real person’s account or exposing private records.
The data should be internally consistent and clearly invented. A realistic layout does not require a real institution, logo or customer.
What should it never be used for?
A LARP bank should not be used as proof of funds, proof of income, payment confirmation or evidence of a real transaction. It should also avoid impersonating a real customer or institution in a way that could mislead another person.
Keeping the tool inside a creative workflow protects both the creator and the audience.
The practical definition
A LARP bank is an interactive banking prop. It looks like finance software but operates only as a fictional presentation.
