Operational efficiency through RFID-enabled smart card sensor technology for identity, access control, and resource management

Abstract This paper presents a novel RFID-based smart card system aimed at optimizing operational efficiency across various applications, including canteen management, identity verification, access control, and resource management. The proposed design uses RFID-enabled smart cards, in combination with a Raspberry Pi Pico microcontroller, LCD display, keypad, and GSM communication module, to create a robust, automated solution for seamless user identification, cashless transactions, and real-time data management. by integrating RFID technology, this system facilitates faster, error-free transactions and provides real-time updates on inventory and attendance, enhancing transparency and decision-making. Here, it has presented the user input containing a specific amount, which serves as the initial part of the system. As the user proceeds through the system management using a unique RFID number and password, the amount is deducted accordingly. This process ensures secure identity verification and controlled access. The study reveals an inverse correlation between manual accuracy and system efficiency, with accuracy efficiency improving from 0.05 to 0.45 as manual dependency decreases from 85% to 50%. Security efficiency also increases from 0.05 to 0.55 as the manual security index drops from 75 to 40. While RFID enhances accuracy and security, higher costs reduce total efficiency. Prolonged RFID processing lowers time efficiency from 0.9 at 10 s to 0.05 at 80 s. Resource efficiency declines from 0.55 at a usage level of 500 to 0.05 at 850. These findings emphasize the need for cost-effective RFID deployment to balance efficiency, security, and resource utilization. Additionally, data analytics from the system offer valuable insights into usage patterns, enabling informed resource allocation and improved operational strategies. While the system holds significant potential for improving efficiency and user experience, considerations such as setup costs and data security are crucial for successful deployment. Overall, this RFID-based solution demonstrates a versatile and efficient approach to enhancing operational performance in diverse environments.
