用RFID+树莓派打造校园无现金支付系统，提升便利与安全。
A RFID Based Campus Wide Payment System
- 基于RFID卡与树莓派构建硬件系统，实现校园服务一键支付。
- 中心化数据库实时同步交易记录，网页端可查余额与流水。
- 适合高校、园区等封闭场景，可拓展至智能停车与考勤应用。
本文提出一种基于RFID的校园全域无现金支付系统，采用RFID卡与树莓派作为核心硬件，支持食堂消费、学费缴纳、图书馆罚款等各类校园服务的便捷支付。系统通过中心化数据库实现实时交易更新与账户余额同步，并提供简洁友好的网页界面供用户查询。设计遵循面向对象原则，完成数据库搭建与硬件集成。实验表明该系统成本低、效率高，显著提升学生与管理人员的使用体验。研究还对比了相似的RFID应用场景，如智能停车与考勤系统，分析其挑战与优化方向。未来展望包括可穿戴式RFID设备、语音支付及区块链技术融合，以进一步增强安全性与易用性。结果证实该系统能有效简化校园支付流程，具备在类似环境中推广的潜力。
原文摘要 · Abstract (English)
This work titled "RFID Based Campuswide Payment System" introduces an innovative cashless payment solution for educational institutions. It uses RFID cards and a Raspberry Pi to enable hassle free payments for various campus services, such as cafeteria purchases, tuition fees, and library fines. A centralized database ensures real-time updates on transactions and account balances, accessible through a simple and user-friendly web interface. This work is involved in designing a secure system with object-oriented principles, setting up databases, and integrating hardware like RFID readers with a Raspberry Pi. The systems are proved to be a cost-effective and efficient alternative to traditional payment methods, enhancing convenience and security for students and administrators. The study also explored similar RFID applications, like smart parking and attendance systems, to identify challenges and improvements. Looking ahead, it envisions features like wearable RFID devices, voice-activated payments, and blockchain integration to boost security and usability. Results show that this system simplifies campus payments and has the potential for broader adoption in similar environments.
