A well-known university in Beijing currently has one campus, and a second campus will be built in the future. The distance between the two campuses is 30 kilometers. The design needs to consider the establishment of campus card management centers on both campuses.
Brief Description of Campus Card
The role of campus cards
The campus card can replace the student ID, work ID, sports card, monthly pass, library card, membership card, dining card, wallet and other documents used on campus, and has the advantages of centralized management and convenient use. The main function of the campus card is to provide users with identity authentication and electronic wallets. All application extensions are based on these two basic functions.
Scope of application of campus card
The scope of application of the campus card includes: school status management-student registration, transcript management, etc.; identification (access control)-use in libraries, teaching areas, student dormitories and other fields; expense management-payment of tuition, grants, and scholarships And withholding fees, etc.; on-campus consumption-used in restaurants, canteens, fast food restaurants, medical treatment, public computer rooms and other fields; shopping-used in supermarkets, retail stores, teaching materials distribution centers and other fields; entertainment-used in stadiums, college student activity centers and other fields .
Main functions of campus card
1. Identity recognition function: The campus card records the identities and basic information of students and teachers, so it can be used as a mark for the identification of teachers and students, as well as student IDs and work cards.
2. Access control management function: in some specific occasions when the identities of faculty and students need to be identified, the campus card can be used for identification. For example, libraries and teaching areas only allow faculty and staff or students to enter, and access to other unrelated personnel can be restricted by setting the software of card readers.
3. Student status management function: when each semester starts, students will register with the school registration center with their campus card and pay tuition and fees. The campus card records the cardholder’s personal identity and saves the cardholder’s information.
4. Time-limited service function: the school’s public computer room or Internet access is charged by hour. After the campus card is used, accurate and real-time billing can be realized through the deduction function of the campus card, and the number of people and time on the computer can be conveniently counted, so as to provide effective data for management personnel.
5. Canteen dining function: Using campus card to pay for meals is one of the important functions of campus card. It plays an important role in the daily life of students. Using campus cards to pay for meals can save time, reduce the workload of staff, and avoid losses caused by errors.
6. Medical and internal consumption functions: The smart card stores basic personal information such as the names, file numbers, ID numbers, departments or classes of teachers and students, as well as personal financial information of teachers, students, and employees, as well as different types of groups of people. Relevant information required for project management and service. Students can use campus cards as electronic wallets instead of cash payment methods when they use campus networks, computer rooms, laboratories, borrowing books, shopping on campus, and seeing doctors in hospitals.
7. Other payment functions: The student card in the campus card can be automatically deposited or deducted by the bank, such as automatically depositing a uniformly distributed non-staple food subsidy on the card or depositing scholarships, student loans, etc. on the designated student card.
8. Inquiry function: You can inquire about teaching equipment, education situation, student situation, books, audio and video materials, etc.
The overall goal and design ideas of the program
Campus card construction background
After ten years of development of smart card-related equipment, the current equipment used in various modes is relatively mature, providing the application foundation for the campus all-in-one card. At the same time, the establishment and improvement of the campus network provides a network foundation for the application of the all-in-one card system. In addition, the gradual enrichment of various subsystems and the maturity of the campus card platform technology provide feasibility for the school’s resource integration.
The goal of campus all-in-one card system construction
The goals of the campus all-in-one card system are:
·Bank end: Realize self-service real-time transfer between bank savings accounts and school card accounts. Teachers and students can use debit cards to implement financial functions such as deposits and withdrawals, consumption, and transfers at bank branches or self-service terminals in various places;
·Campus end: The campus card will replace various certificates and bills in the school, including student ID, teacher work ID, medical ID, library card, cash, meal ticket, water ticket, air ticket, bath ticket, etc.;
·Achieve one card to complete all consumption functions in the school;
·Achieve one card to complete all the identity verification functions in the school;
·Realize the unified financial management within the school, and the large concentration of data reduces the work intensity of the financial staff;
Realize the centralized management and global sharing of student, faculty and staff identity files and public information;
·Integrate the various management systems in the school to achieve the unification of the entire campus online application system, integrate the original relatively independent and unconnected management systems, straighten out the business process, and tighten the cooperation and information exchange between various departments;
·Improve the management level of the school, improve the work efficiency of the school, and make the management of the entire school reach a new level;
·Through the use of various subsystems, standardize the internal management of various departments and save management costs.
Design elaboration
After analyzing the various needs of the university, we believe that a card system solution suitable for the future development and construction of the school should be functional: it can fully meet the needs of the school, and the various indicators of the software and hardware products meet or exceed the school’s The actual requirements, and the products provided should be at the leading level in the industry; in terms of investment: the system should be able to protect (or integrate) the existing application system, reduce investment, and the system should be ahead or equal to the current state of the art technology. It is an important step in the construction of a digital campus; in management: provide an information management exchange platform for each application subsystem, making the school’s daily information management easier and more efficient; financially: provide centralized information management for each application subsystem The clearing platform can not only realize the unified processing of financial data, but also must ensure the security of the financial data of all parties; in terms of standards adopted: it should meet the standards of relevant management departments, such as data format and financial statement format. standard.
At the same time, the campus all-in-one card system should be an important part of the construction of a digital campus, and it should fully comply with the digital campus’s “unified planning and step-by-step implementation” construction concept. The software and hardware provided should be able to meet the requirements of the school’s future application expansion.
Security design considerations
The safety design of the system should grasp the overall situation and fully consider all factors.
1. Card security: the forgery of the card or the tampering of the data in the card, as well as the verification of the device and the forged card during the actual use of the card. The card used in this case is read and write operations through antenna induction. In the case of grid interference, induction critical points, etc., errors in reading and writing information may occur. Generally, a lot of cardholder’s information such as amount, name, unit, student number, etc. are written in the card. Taking into account the frequency of use, convenience and stability, the frequently read and written information such as the amount and rarely used information Information such as name and student number is equally divided into different sectors, so that different application systems use their own areas and do not interfere with each other. It also greatly improves the transaction speed of the POS machine to the card in the integrated consumer system, which is suitable for the school dining concentration. , The demand for short transaction time is required to avoid reading and writing card errors caused by the increased probability of students pulling out the card in advance due to the excessively long time for the reading and writing equipment to operate the card. In addition, the information storage in the card adopts a backup mechanism. When reading and writing the card, both sectors are correct, otherwise the alarm will be issued; if the information is checked, the check code is wrong, the system will also alarm, prohibiting the use of the card.
2. Protection of consumer equipment (POS machine): tampering and forgery of transaction flow in consumer equipment (POS machine).
3. Secondary transmission process: data theft and forgery during 485 network transmission or secondary TCP/IP network transmission.
4. Secondary server storage: network attacks, anti-virus, tampering or deleting the secondary database.
5. Network (local area network) transmission process: intercept or steal transmission data, crack data packets, and forge transaction data.
6. Central database storage: network attack, virus, hacker intrusion, database tampering or deletion.
7. Security administration: Security is a relative concept. Another security factor that cannot be ignored during the entire operation of the all-in-one card system is internal management. Only advanced security technology plus an effective management system can ensure the security of the entire system.
8. Communication protection: The communication line is wired in parallel, and the open-circuit communication chip is used in the machine, which effectively prevents the single-machine busy phenomenon, can ensure that the single-machine communication failure does not affect the entire network, and can also effectively prevent communication interference and abnormal conditions.
9. System anti-interference ability: The switching power supply is added to the POS machine to make the voltage range wider, avoid the machine heating phenomenon, and make the machine performance more stable; at the same time, the filter is used to further improve the anti-interference ability of the equipment, especially for radio frequency cards machine.
10. The necessity of using a backup battery: There is a high-performance backup battery in the POS machine, which can ensure normal operation for more than 8 hours in the event of a power failure.
11. Single consumption limit and limit consumption function: This function can set the limit for each consumption of the card. When this limit is exceeded, the password must be entered to continue consumption, which can avoid malicious consumption by the card picker. Limited consumption means that you can only consume once or several times in a day.
12. Cumulative consumption limit function: You can set the card’s one-day cumulative consumption limit. When this limit is exceeded, you must enter a password to spend normally, which can minimize the loss caused by the cardholder’s failure to report the loss in time.
