## Overview

This is a small Tkinter desktop app for generating synthetic payment-card details for testing or education. The user clicks Generate Card; the GUI handler selects a card type and coordinates number validation, name and ZIP retrieval (with offline fallbacks), then formats and displays the details. Copy to Clipboard transfers the displayed text to the system clipboard. The single source file implements all runtime layers; external API calls are documented and visible in source. The graph reflects that compact structure rather than packaging artifacts.

Main entry points: [`random_card_generator.py`](https://github.com/blessed-shammah/random_card_generator/blob/main/random_card_generator.py) (Card orchestration)
