This feature provides a **seamless and secure instant payment** option. When selected, the system instantly generates a unique QR code.

ShopZone is a modern Django project that provides:
β A high-contrast, dark-themed online product catalog.
β A secure, transactional checkout system with atomic stock deduction.
β Comprehensive inventory and product management (via Django Admin).
This is not a simple template β it is a secure e-commerce solution focusing on premium presentation and data integrity.
β’ **Atomic Stock Deduction:** Uses Django transactions to guarantee stock reduction or full rollback.
β’ **Concurrency Safety:** Employs select_for_update() to prevent overselling during simultaneous checkouts.
β’ **Discount Logic:** Checkout automatically validates and applies the discount_price if it's lower than the original price.
β’ **Stock Tracking:** Stock is checked client-side and verified again server-side at checkout.
β’ High-Contrast UI: Dark theme accented by vibrant Orange/Yellow for a premium feel.
β’ Persistent Cart: Uses local storage (JS/jQuery) to maintain cart items across sessions.
β’ Price Clarity: Clearly displays original price with a strike-through next to the discounted price.
β’ Two-Step Checkout: Provides an Order Summary step before final payment confirmation.
Backend: Django 5 (Python)
Database Safety: django.db.transaction + select_for_update
Frontend: Bootstrap 5 + Custom CSS (Dark Theme/Orange Accents)
Client Cart: JavaScript (localStorage) / jQuery
Database: SQLite (Development)
