I. I NTRODUCTION The rapid advancement of modern technology is transforming traditional payment systems. While paper money has long been the global medium of exchange, it is increasingly being replaced by digital alternatives such as magnetic cards and automated teller machine (ATM) cards. These technologies enhance convenience by eliminating the need for cash-based transactions. Radio-Frequency Identification (RFID) technology further advances this trend by leveraging electromagnetic fields to automatically identify and track objects. An RFID system typically comprises a tiny radio transponder, a receiver, and a transmitter, enabling seamless and secure data transmission. In the context of academic institutions, traditional cashbased payment systems present significant challenges, including inefficiency, inconvenience, and security risks. Students must carry cash for various purposes, such as tuition payments, canteen expenses, library fines, and admission fees, creating risks of theft and loss. Moreover, cash-based transactions often lead to delays and administrative inefficiencies.
Radio-Frequency Identification (RFID) technology has become increasingly prevalent across various industries due to its ability to facilitate automated, contactless identification through radio signals. Gaikwad et al. (2017) highlighted its potential in cashless systems to provide secure and convenient payment methods. In India, RFID is already being utilized in toll systems to reduce congestion and streamline transactions, demonstrating its effectiveness in addressing inefficiencies (Mall and Shaikh, 2017). The continuous evolution of RFID technology is expected to contribute significantly to various societal and industrial advancements (Duroc, 2018). Several studies illustrate the diverse applications of RFID technology. For instance, an IoT-based smart parking system integrates RFID cards and IR sensors to minimize waiting times and operational costs while promoting sustainability through reduced paper usage. This system automates parking billing using RFID-tagged vehicles, enhancing both efficiency and revenue generation for facility owners. Similarly, RFIDbased attendance systems, as developed by Manav Rachna International University, simplify attendance tracking in educational and professional environments, offering real-time monitoring and enhanced security.

Another notable application is the RFID-based child security system, which combines RFID, GPS, and GPRS technologies to monitor student transportation. This system enhances safety by tracking students’ movements and providing realtime updates to parents and schools, thereby addressing critical safety concerns (Shabaan et al., 2013). RFID-based cashless canteen payment systems further emphasize the technology’s potential to simplify and automate transactions, enhancing customer convenience in daily operations. In comparing RFID with Near Field Communication (NFC), RFID stands out for its longer range and faster data transfer capabilities, making it suitable for one-way communication in large-scale applications. In contrast, NFC is more suited for short-range, secure, and bidirectional communication scenarios, such as mobile payments. Despite its advantages, RFID technology faces challenges such as reader and tag collisions. Reader collision occurs when signals from multiple RFID readers interfere, while tag collision arises from simultaneous data transmission by multiple tags in a single field. Anti-collision protocols and sequential data collection mechanisms have been developed to address these issues, ensuring the accuracy and efficiency of RFID systems. The literature demonstrates that RFID technology is highly versatile, offering innovative solutions across multiple domains. These studies provide valuable insights and a foundation for the development of the proposed RFID-based campuswide payment system, which aims to streamline financial transactions in an academic setting.
