Mobile phone RF-SIM card "mobile phone card" integrated management system uses the most advanced 2.4G technology in the world. The introduction of this system has brought great convenience to the management of society, colleges and universities, and caused great repercussions. At present, in colleges and universities, the management of documents, archives, and canteens for a large number of people are not related. There is no mutual connection between departments, resulting in waste of manpower and financial resources, and low efficiency. Non-contact IC card series management system, can be used for college staff and students' documents (including faculty staff faculty certificate, student ID card, library card, pass card, etc.), student status file management, faculty and staff attendance, canteen management The functions of computer room management, parking lot, swimming pool management, commissary and other small amount of consumption are integrated into one card, so that the college can get rid of the cumbersome and inefficient management style and put more energy into scientific research and study. . The design of this program is based on the actual requirements of the campus, based on the principles of scientific and reasonable, economical and practical, advanced and reliable, and compatible and expandable. The system is designed with full consideration of the advancement of equipment and technology. The system adopts 2.4G RF-SIM card and non-contact IC card (8K memory, readable and writable IC chip), and its storage structure allows the card to be used in multi-application systems. With up to sixteen different applications, managers can get rid of the cumbersome management methods while making users feel it's fast, convenient and easy. We have fully considered the scalability of system capacity: 1. The network design adopts the bus system. All equipment management hosts are hung on the bus. When the system is capacity-increasing, it is only necessary to directly connect the management equipment to the bus without modifying the line. 2. The system application software can support the use of 100,000 cards, which can fully meet the needs of future personnel growth; 3, the real one card, one library, one network and one platform. 4. Using the non-contact smart card system to realize the campus canteen charge, book borrowing, on-board charge, hawker charge, bathhouse charge, stadium charge, hospital charge, club charge, the integrated card management system only needs to present the recharged mobile phone card when using The effective distance of the charging machine sensing area can be used for consumption. It eliminates the drawbacks that may occur in the old consumption methods in the past, namely, speeding up the operation, improving the consumption mode, strengthening the security of the system, and facilitating intelligent management. The network design adopts the bus system, and all equipment management hosts are hung on the bus. When the system is capacity-increased, it is only necessary to directly connect the management equipment to the bus without modifying the line; All terminal devices of smart card products are single-chip microcomputers with microprocessor and memory to ensure the accuracy of data calculation and data storage integrity; IC card adopts PHILIPS company's M1 type logic encryption memory card, with 32 unique serial numbers in the world. To prevent copying, cards can be triple-encrypted, which is more secure and stable than magnetic cards and ID cards that require real-time networking. The system upper management software runs on the existing enterprise or campus LAN, and each terminal device is connected to the workstation near the local area network. All cards are issued by the management center after the establishment of personnel data. If there is personnel data software before, the original database data can be called without having to re-enter. The consumption data is collected by each management workstation and transmitted to the server. The statistics of each report are generated by the management workstation accessing the server database. Section 1, Overview: The card system is a mobile phone card-based application system developed around the needs of enterprises. The system builds a series of application subsystems on the basis of the platform of cartoon (Cartoon, Coton, Netcom), allowing users to implement a single individual. Application systems (such as time and attendance systems) can also implement multiple application systems or all-in-one card systems simultaneously or step by step. When a user expands from a single application system to multiple application systems or a full-service card system, there is no need to replace the cards and devices that have been put into use, and it is only necessary to easily add new application modules to the implemented application platform. Greatly shortened system implementation time and saved implementation costs. The card system can include the following modules: “Personnel Systemâ€, “Card Managementâ€, “Access Control Systemâ€, “Attendance Systemâ€, “Canteen Systemâ€, “Rooting Systemâ€, “Conference Sign-in Systemâ€, “Water Control Systemâ€, “Control Systemâ€, etc. Wait. The second section, the principle of one card: The card system is a stable, reliable, easy-to-use and highly scalable smart card management system based on the three-way card: Cartoon (this system uses mobile phone RF-SIM card and MIFARE 1/IC card) The data of each application subsystem on the card can be interoperable, but without losing the independent security requirements of each application subsystem, the common data of each subsystem is stored in the basic information area, which can be read by each subsystem but cannot be rewritten, each sub- System-specific data is stored in a designated private service data area, which can only be read and written by the subsystem, and other subsystems cannot access it. The data that needs to be exchanged between subsystems is stored in the data exchange area and can be called from each other. Through the establishment of the basic information area, data exchange area and dedicated business data area mechanism, the technical requirements of "cartoon" are perfectly realized. This allows a card to be issued only once and can be used in a variety of application subsystems. The MF1 IC card has 16 sectors, and the specific allocation of sectors can be determined according to user requirements.
