## Overview

This is a small Java command-line bank-transfer application. Its main workflow collects sender, recipient, and transfer details; processes a transfer with the sender account’s applicable fee; and, on success, saves and displays a receipt. The source also defines customer registration and sign-in methods, but they are not wired into the transfer workflow. The graph reflects the sampled source; the README is empty, so no further capabilities or integrations are documented.
