Conception of Campus Smart Card Application System

With the continuous expansion of the national education scale, the number of students in the school has increased rapidly, and the business volume of various management tasks has increased dramatically. Since various management tasks lack the necessary information sharing and information exchange with each other, a large amount of basic information is repeatedly input into each independent local management system. This not only increases the workload, but also causes information inconsistency. It also results in the inability to use the stored information in many occasions, and makes it difficult to improve the management level.

At present, the construction of the campus network of various colleges and universities is gradually unfolding. With the completion of the campus network, the transmission, storage and processing of various types of information can be completed on a computer network. In this way, information collection, which is one of the basic elements of information systems, becomes a bottleneck. Because the users of the campus network are students and faculty members, the number is thousands or even tens of thousands. The time and space of their activities are relatively concentrated. The campus network needs to provide services for them in teaching, research, book lending, life and entertainment. It is necessary to identify their identity, identify their rights, and serve the project. Record the results, charge for various paid services, etc. All of this requires a lot of manpower and time, which is not conducive to giving full play to the role of the campus network and affecting the efficient operation of the campus network. In recent years, based on modern information technology and electronic technology, smart card technology has developed rapidly, providing an excellent opportunity to solve such problems.

1, the characteristics of smart cards

A smart card, also known as an IC card (Integrated Circuit Card), is made by embedding an application-specific integrated circuit chip on a standard-sized plastic sheet. The integrated circuit chip is composed of a microprocessor and a memory, has an in-card operating system, has computing and storage capabilities, and can encrypt information stored by a computer system, and has a read/write security protection mechanism. The IC card has the characteristics of large storage capacity and good confidentiality, and is a product of high integration of computer hardware technology and software technology.

The IC card face is printed with the cardholder's name, gender, department and other personal basic information and photos, as well as the card issuance department and time. In addition to storing the cardholder's personal basic information, the card also contains the IC card production and distribution code, user category, permissions, password, registration information and expiration date, deposit balance and other information.

Compared with magnetic cards, barcode cards, and punch cards, IC cards have excellent security, and the chips themselves provide better protection for security. The verification of the identity of the cardholder can be completed inside the IC card, and the access to the information in the card can be performed after the password is checked, so that the information has reliable security assurance, and the burden on the network can be significantly reduced.

With the help of the computer network, the IC card is used as the recording medium of the individual information through the "network-card combination" method, and the computer system is used as the recording medium of the group information to realize one card multi-purpose. In this way, it is convenient for users and system administrators, and the campus network can play a greater role to further promote the modernization of school management.

2. The basic composition and working process of the smart card application system

The IC card system is an integrated multi-user information system. The system consists of an IC card, a front-end device, a background device, a network system, a database system, system software, and application software. The front-end equipment includes an IC card reader and a computer, which reads out information in the IC card, authenticates the identity and rights of the card holder, and issues an authorization request to the background device through the network if necessary. After confirming the cardholder's legal identity and authority, the corresponding service can be provided and the relevant information can be written into the IC card and database. The background device refers to the server on the network. It connects several front-end devices through the network, mainly implementing the management and data processing of the authorization process.

3. Design goals and design principles of campus smart card application system

3.1 Design goals

The campus smart card application system is based on the campus network, with the IC card as the personal information carrier, and the IC card reader as the front-end device of the local area network, and directly exchanges information with the cardholder. It has the characteristics of many users, wide service items, fast running speed and high safety performance. Therefore, the design goals of the campus smart card application system are:

(1) Build an advanced, practical and campus network system with a certain scale. Its services include teaching, research, library, administrative management and other departments;

(2) Sharing information between departments;

(3) Achieve rapid identification and service, automatic collection of charging information;

(4) Replace the current student ID card, library loan card, meal card, and machine card with a smart card, and establish a personal fund account management system to realize one card multi-use.

3.2 Design Principles

The construction of IC card application system involves many aspects of school management, information technology, network technology, etc. It must be developed in strict accordance with the idea of ​​software engineering to ensure the success of development and ensure the normal operation of the system. There are several principles to adhere to during the development process:

(1) The construction of the campus smart card application system should be carried out in accordance with the specifications of the network construction, combined with the actual situation of the school and the development plan;

(2) Pay attention to the use of advanced technologies and products in computers, networks, databases, etc. This is an important prerequisite for ensuring system performance;

(3) to ensure the practicability of the system function, and to meet the requirements of use;

(4) Establish a sound security mechanism to provide the necessary fault tolerance to ensure the reliability and security of the system;

(5) In order to facilitate the expansion of the system, there should be good connectivity and openness.

4, the function of the campus smart card application system

According to the overall requirements of system design, the campus smart card application system consists of eight subsystems: card issuance and authorization management, personal account management, student status management, course selection and performance management, laboratory management, library management, canteen management and medical office management.

4.1 Issuing and Authorization Management Subsystem

The basic information such as the cardholder's name, gender, department or class and its photos are entered into the computer management system. The photos can be obtained by digital photography or by ordinary photo scanning. The card-making device writes the relevant information to the chip in the card and prints it on the card surface. At the same time, authorization is given according to the situation of the cardholder (such as teachers, undergraduates and graduate students), and the production and distribution codes of the IC card are recorded. The cardholder can report the loss after losing the card.

4.2 Personal Account Management Subsystem

A fund account is established for each card, and the cardholder can deposit any amount of funds and withdraw cash. The system manages all accounts, and can complete accounting processing, data statistics, etc. of funds deposit and expenditure. The establishment of a personal fund account will make it easier for cardholders to pay various fees in the school (such as tuition, meals and medical expenses), and strengthen the management of various school fees.

4.3 Student Status Management Subsystem

Each student registers with the card and pays the tuition fee. The system stores the information in the database and writes it to the smart card. Use the registered smart card to select courses, enter the lab and computer room, borrow books from the library, eat in the cafeteria, and visit the infirmary.

4.4 Course Selection and Performance Management Subsystem

Each student holds a registered smart card for class selection. The scope of the course is limited according to the major and grade of each person. The student's transcript is created with the selected course and the specified compulsory course, and the grades and credits are credited to the transcript at the end of the semester. The system can conduct statistics and analysis on the results of all students in various ways for the reference of leaders and teachers at all levels.

4.5 Laboratory Management Subsystem

During the teaching process, students often enter the lab and computer room, some of which are timed. The terminals of the system can be set at these locations. Each student enters with a registered smart card. After entering the password, it can be used and automatically timed. When leaving, it will automatically settle through the personal account management subsystem according to the actual usage time and charging standard. The system will give you a hint when the funds in the account are reduced to the minimum during use. It can record the use of related equipment, conduct statistics and analysis of relevant data, and provide relevant departments with equipment usage analysis to determine equipment maintenance and procurement plans.

4.6 Library Management Subsystem

Book lending is a daily work in the library of colleges and universities. Combining smart cards with library information management systems can greatly improve the level of book management and service quality. Students and faculty members borrow smart cards, and the system can quickly and accurately record borrowing information. When the book is lost, damaged, or need to be fined, the system will automatically settle through the personal account management subsystem, which is fast and accurate, and can strictly enforce the rules and regulations.

4.7 canteen management subsystem

When the meal is eaten in the cafeteria, the smart card is inserted into the reader/writer of each service window. When the staff inputs the price of the meal, the system automatically subtracts the corresponding amount from the personal fund account. Data statistics and analysis can be performed accurately and in a timely manner, completely solving the health problems caused by the use of cash or food tickets. It also avoided the loss of meal tickets and blocked management loopholes.

4.8 Infirmary Management Subsystem

When you are in the infirmary, you can automatically complete the registration and various fees, and you can conduct statistics on the health of the staff and students.

5 Conclusion

Based on the campus network, IC card technology can fully utilize the role of the campus network, realize automatic data collection and identity identification, and realize information sharing. This is an effective means to establish a modern and efficient management system.
