With the rapid advancement of information technology, the concept of "smart campuses" has become a new direction for managing universities and enterprises. To achieve goals of safety, efficiency, and intelligence, many campuses and enterprises are incorporating RFID (Radio Frequency Identification) technology for identity verification, attendance management, asset tracking, and access control. RFID, which uses radio waves to read and transmit data, enables fast and precise information management, offering a transformative management experience. How RFID Works: Collaboration Between Readers and Cards RFID technology comprises two key components: RFID readers and RFID cards, which interact through radio waves. RFID Cards: These small electronic tags include a chip and an antenna. The chip stores a unique Electronic Product Code (EPC) and other essential information, while the antenna transmits the stored data via radio waves. RFID Readers: These devices read and write information on RFID cards. Equipped with antennas, receivers, and processors, readers emit radio waves to activate the chip in an RFID card when it enters the detection range. The chip responds by transmitting the stored information back to the reader, which then processes and sends the data to a backend system for further use. This contactless communication makes RFID far superior to traditional barcodes and magnetic stripe cards in terms of speed and convenience. RFID systems can also identify items from a distance and read multiple tags simultaneously, greatly enhancing their flexibility in various applications. Applications and Benefits of RFID in Campus Management Identity Verification and Access Control RFID cards are widely used for identity verification and access management in smart campuses. For example, students with RFID-enabled campus cards can quickly gain access to dormitories, libraries, or laboratories. When a student passes through an RFID-enabled gate, the system automatically reads the card’s information, verifies it against the database, and unlocks the gate upon approval. This contactless verification method improves efficiency and reduces the security risks associated with lost or duplicated cards. During public health crises, the touch-free nature of RFID further minimizes physical contact, enhancing campus safety. Attendance and Academic Activity Management RFID also streamlines class attendance and the organization of academic activities. Students only need to carry their campus cards through RFID-equipped entrances to have their attendance automatically recorded, eliminating the time-consuming process of manual roll calls. In addition, RFID simplifies participant verification and attendance tracking for academic events, conferences, or large campus activities. Some institutions even integrate RFID with credit systems, automatically logging students' participation in events to support academic evaluations.
