Product Verification System

Overview

The Product Verification System is designed to generate unique 13-digit random codes for products, ensuring authenticity and preventing misuse. This system allows for one-time verification of product codes, stores user details for marketing analysis, and includes a CRUD API for managing product information.

Features

• Code Generation: Generates unique 13-digit random codes for each product.
• Excel Export: Automatically downloads an Excel sheet containing all generated codes.
• One-Time Verification: Ensures product validity can be checked only once to prevent code misuse and counterfeiting.
• User Data Storage: Stores user verification details in a database, aiding marketing efforts and performance analysis.
• CRUD API: Provides endpoints for creating, reading, updating, and deleting product information.

How It Works

1. Generate Codes:

   • Use the system to generate unique 13-digit codes for your products.
   • An Excel sheet with all the generated codes is automatically downloaded.

2. Verify Product:

   • Users verify their product using the unique code.
   • The system allows one-time verification to prevent code reuse.

3. Data Storage:

   • Upon verification, user details are stored in the database.
   • This data helps the marketing team analyze product performance across different regions.

4. Manage Products:

   • Use the provided CRUD API to manage product information.
   • Easily update product names or add new products as needed.
