Yilai Campus Card System is a network system suitable for campus consumption and management with IC card as the information carrier. The all-in-one card replaces various personal certificates and cash payment methods used in school management and campus life, and realizes various functions such as living consumption, student status management, identity authentication, and online payment on a small IC card. The campus card connected to the bank can be used for deposit, withdrawal, cash withdrawal, and consumption at bank outlets and designated merchants inside and outside the school. The popularization and use of campus cards will greatly facilitate the lives of students and faculty and alleviate their troubles of carrying various certificates.
A modern school cannot do without modern management. The campus card integrates the powerful functions of the smart IC card and the digital concept of the computer network into the campus, integrates the various systems of the school, dynamically grasps the situation of each card holder, and greatly improves the management level of the school.
The goal of Yilai Campus Card is to distribute inductive IC cards among the students and faculty of the school, fully replacing existing documents including machine-readable strip cards, and cooperating with other information infrastructure of the school to promote the level of campus information management. improve.

Main performance introduction
The IC card in the campus card application is mainly used for identification, electronic wallet consumption and recording application characteristic information. It is used as a certificate for students and faculty in the school. It is used in teaching, daily life and management to identify and manage basic personal information And the corresponding charging location, implement one card, multiple use, one card.
It is perfectly integrated with the campus identity authentication system and used as a campus online identity verification method. Ensure the security of network application services.
The school is divided into two parts: students and faculty members, establishes a unified issuance management mechanism for campus cards, and through the promotion of campus card application projects, gradually improves the school’s unified basic data management system to ensure the safe and effective use of campus cards.
The campus card is managed independently by the school, and those who lose the card can quickly reissue a new card after reporting the loss, which is convenient for cardholders and is conducive to the management of the school.
Use the campus network to establish a network operating environment for the campus IC card system to realize the network transmission of the basic data of the campus card, especially the blacklist of card loss reporting can be downloaded in real time and effectively, to maximize the protection of cardholders’ interests and ensure the campus Safe operation of the card system.
The campus card application system can be compatible with the original management system of each application unit, and provides a good information interface. As long as a small amount of modification is done, it can run in parallel.
Campus All-in-One Card System-The Development of All-In-One Card System
It has been six or seven years since the “One Card” was proposed. From the connection of the first few small systems to the integration of more than a dozen systems throughout the school, to the now popular bank-school one card, it has undergone continuous development and changes. Finally passed the concept stage, although it is far from reaching the real maturity stage, it has reached the real implementation stage.
The card includes three parts: the campus internal system, the interface with the bank, and the bank internal system. The latter two parts are relatively simple and mature in function. The most difficult part is the campus internal system, which includes more than a dozen subsystems and a variety of complex systems. Technology. The campus card has gone through multiple stages of development.
However, the realization of the campus all-in-one card is not an easy task. In practical applications, we often see various solutions. The most common one should actually be called POS all-in-one card. The realization of this “all-in-one card” relies on POS consumer devices, that is, POS devices are installed in all locations where consumption is involved. When consuming, the user generally needs to manually enter information such as the amount after swiping the card. There is no problem installing such a system in canteens, supermarkets, etc., but it is difficult to install it in computer rooms, libraries, etc., while using the computer room management or book borrowing system, on the other hand, it is difficult to input the amount of money. Really play the role of the “all-in-one card” system.
Although the other type of all-in-one card uses the same card within a certain range, there is no “communication” between the systems. Each system uses the same card, but the card is only an identification tool. The various subsystems cannot communicate or share information. Each subsystem has its own student file management and its own account management. For example, the canteen and the computer room can share a card, but students need to pay separately in the canteen and the computer room, and the fees paid cannot be consumed uniformly among different departments.
A true all-in-one card should have the following characteristics: One is that each subsystem shares an account, and operations such as account opening, loss reporting, payment, etc. only need to be performed once and completed in real time. The second is that it is closely connected with various subsystems and does not depend on the POS machine. For example, the machine room management system directly calculates the cost and deducts the fee, without manual operation of the POS machine. Third, in addition to consumption functions, it should also include management functions, such as attendance and access control.
Campus All-in-One Card System-Key and Difficult Issues
The first key issue is how to complete the integration of various subsystems. The one-card system generally includes nearly 20 subsystems, involving multiple technologies such as hardware control, database, system security, smart card, data transmission, and network identity verification. Every system requires a very complicated and long maturation process. No matter how powerful a company is, it is impossible to achieve a relatively complete level of every system. Therefore, the best development method is to cooperate with various mature system manufacturers for system integration.
The second is the technical integration of the various subsystems. Each system must use an account number and ensure the real-time update of information. When a transaction occurs in one subsystem, all other sub-systems must be notified in the shortest possible time. System, when the network or other systems fail, it is also necessary to ensure the operation of the system, and when the network is restored, it must be able to restore the unupdated data in a timely manner.
Campus Card System-Design Principles
1. General principles
The system is designed in accordance with the most advanced third-stage technology of the “All-in-One Card”, which can realize the interconnection and information sharing between the systems.
2. Design principles
1. Network management
All the subsystems are connected with the main control system and have communication capabilities, which can easily transmit data and conduct unified queries and statistics. For example: when a user reports a loss, all parts of the system should obtain the loss report information in the shortest possible time to ensure that the user’s interests are not lost; when statistics are needed, it should be able to quickly collect the information of each toll point and form a report.
2. Independent design
All subsystems can operate independently, and when a system or main control terminal is shut down or fails, it will not affect the operation of other systems.
3. Security
Using a variety of technical means to ensure data security from multiple aspects such as data transmission, physical storage, and logical encryption.
4. Maintainability
When the system fails, it should be easy to judge and can be solved quickly.
5. Openness
The system reserves a general information exchange interface, which can share information with the school’s existing and future systems.

Although the EM card and HID card cannot write data, since Zhiyuan adopts a unique distributed network database solution, it can ensure that it can work normally when the data center or network fails.
Campus All-in-One Card System-Subsystem Introduction: All-in-one Card Platform
1 Overview
The all-in-one card platform is the core part of the entire campus all-in-one card management. It is responsible for the maintenance of public data (such as student information and smart card information) in each system, as well as the transmission of information between various subsystems. Each relatively independent subsystem can become a whole only through the data exchange function of the all-in-one card platform.
2. Basic principles and design ideas
The simplest all-in-one card platform requires the use of central data between various subsystems. The advantage of this is that only one piece of data needs to be maintained, there is no problem of data balance and transmission, and the design is simple. But the problem is that the requirements for the network are very high, requiring high-speed and stable operation of the network. Once the network fails, the system will be in a paralyzed state. At the same time, various subsystem manufacturers are required to modify programs and abandon the original data, which will greatly increase errors. The probability.
ZHIYUAN’s all-in-one card platform adopts a completely distributed data design. While maintaining the central data, the all-in-one card platform maintains the data independence of each subsystem, and balances the data in each subsystem through the network. This greatly reduces the dependence on the data center and network. When the data center and network fail, the use of the system will not be affected. At the same time, each subsystem manufacturer no longer needs to modify the data structure, which reduces the probability of program errors.
