IoT Based Integration of RFID Wireless Payments via GSM-GPRS Networks

In response to the pressing need for secure and cashless transactions, this project introduces an IoT-based RFID wireless payment system<br>with GSM-GPRS network integration. The primary aim is to revolutionize payment methods by leveraging RFID technology and a<br>robust software infrastructure. The system comprises a frontend developed in React, allowing users to manage RFID tags, names, and<br>associated amounts. The backend, powered by Java, Spring Boot, JPA, and Hibernate, connects to a MySQL database for seamless data<br>storage and retrieval. The user database is enhanced to accommodate RFID details. New API endpoints are introduced to facilitate RFID<br>tag recharging and user creation. The hardware components include a microcontroller, RFID reader, RFID tags, power supply, GSMGPRS network module, LCD, and a 4x3 keypad. The microcontroller orchestrates communication between the RFID reader, LCD, and<br>keypad. RFID tags are linked to user accounts, and the system supports secure transactions via the GSM-GPRS network. The LCD and<br>keypad contribute to a user- friendly interface. Extensive testing is conducted, covering end-to-end functionality, security measures, and<br>real-world simulations. The system successfully integrates hardware components with the frontend and backend, ensuring a streamlined<br>user experience. The research paper provides detailed insights into the architecture, implementation, and testing phases of the project,<br>highlighting its potential to transform payment systems and promote a cashless economy.
