The RFID technology application system campus card has been widely used in modern smart campus construction, integrating identity recognition, payment, attendance management, and security monitoring into one, achieving an efficient management model of "multiple functions with one card and universal use.".

Identity Authentication and Access Control: Students wear campus cards or smart wristbands integrated with RFID chips, enabling seamless, contactless passage in areas such as school gates, dormitories, and libraries in just 0.3 seconds. Some institutions employ dual verification using RFID and facial recognition to eliminate the risk of unauthorized access and enhance security.
"Alipay" must be translated as "Alipay"  Smart Payment and Lifestyle Services: After binding an electronic wallet to a campus card, users can complete cashless payments in scenarios such as cafeterias, supermarkets, and laundry rooms, handling tens of thousands of transactions daily. Some universities also support Alipay-linked top-ups to enhance convenience.
Teaching and Attendance Automation: By deploying RFID readers in classrooms, the system can automatically record student attendance and synchronize it with the academic management system, enabling seamless check-ins. Additionally, the system supports dynamic roll calls and absence alerts, helping teachers manage classrooms efficiently.
Resource Usage and Facility Management: Students can reserve facilities such as laboratories and gyms using their campus cards. Equipment like showers and water dispensers support card-based power access and are billed by usage duration, effectively conserving energy.
Home-School Coordination and Safety Assurance: When students enter or exit the school gate, the system automatically identifies and sends an SMS notification to parents, stating, "Your child *** arrived at school at 8:00 AM," achieving real-time synchronization of home-school communication. Some systems also feature off-campus tracking capabilities (combining GPS + GPRS), enhancing safety during students' commute to and from school.
Moreover, with technological advancements, the RFID-SIM card integrates RFID functionality into mobile phone SIM cards, enabling features such as campus access and payment without the need for phone replacement. It has been piloted in multiple schools across Shenzhen, Hubei, and other regions, promoting a smart lifestyle model where "the phone serves as the campus card.".
