The secure instant payslip access using permission-based authentication is a full-stack web application developed using React.js with Prime React components for the front-end, Node.js with Express.js for the back-end REST API, and MySQL as the relational database management system. The system is designed to automate and streamline the entire payroll and payslip management process for organizations. The application provides complete Employee CRUD (Create, Read, Update, Delete) operations, allowing HR administrators to efficiently manage employee master data including personal details, designation, department, salary structure, and bank information. Each employee record is associated with a unique QR code that is dynamically embedded in the generated payslip PDF. The QR code links to a token-protected URL, enabling secure and verifiable payslip downloads while preventing unauthorized access. The system implements Permission-Based Access Control (PBAC) using JWT (JSON Web Token) authentication. HR administrators are granted full access to manage employees, configure salary components, and generate payslips in bulk. Employees, upon login, can only view and download their own payslips, ensuring data privacy and access security. The payslip PDF includes a detailed breakdown of earnings (Basic Pay, HRA, DA, Conveyance Allowance), deductions (PF, ESI, TDS, Professional Tax), and net pay calculations. The responsive Prime React interface provides a rich user experience across desktop and mobile devices. The MySQL database ensures structured and persistent storage of employee records, payroll transactions, user roles, and access permissions. The system is scalable and suitable for organizations of all sizes
