With the continuous progress and development of society, the original consumption and management models of schools can no longer adapt to the new development requirements. Based on the current status quo, the “bank-school all-in-one card system” came into being. The so-called “all-in-one card” refers to the use of cards in schools where cash, tickets, or identification is required. This management model replaces the traditional consumption management model, bringing efficiency, convenience and safety to school management.
1. The practical significance of the silver school all-in-one card
Student life: Students have student IDs, meal cards, borrowing cards, bank cards, telephone cards, etc., ranging from three or four to six or seven, which brings a lot of inconvenience to students’ daily life.
Campus management: Each of the existing systems has independent authentication methods and consumption methods; schools cannot achieve unified management, and resources cannot be rationally used and shared.
Banking services: Colleges and universities are becoming key customers of banking services. The Bank-School Card will be a better and more convenient way for banks to serve and profit from campuses. Banks will also use their best The service cultivates and competes for potential customer groups on campus.
Telecommunications services: The competition in the telecommunications industry is unprecedentedly fierce, and campuses have become another focus of their competitive strategy, not only to serve the campus, but also hope to obtain more potential customers and more benefits in this way.
2. Technical conditions of the bank-school all-in-one card
Mature network technology: The one-card system is based on the campus network and uses advanced network security technology to ensure the integrity, stability and security of various data transmitted on the network.
Advanced card technology: The gradual maturity of card application technology (including system software and card equipment) provides the application technology foundation for the all-in-one card system.
Secure key system: 128-bit international standard DES encryption algorithm and other multi-layer security authentication methods provide the basis of security technology.
3. Functions that can be achieved by the Bank-School Card
Daily consumption: To achieve all consumption on campus, only one campus card is required for consumption in student canteens, faculty restaurants, shops, supermarkets, bookstores, barber shops, community service centers, laundry shops, photocopy shops, and various venues.
Identity Recognition: Realize all the identity recognition functions on campus, such as library access, book borrowing, computer center, gymnasium, swimming pool, playground, equipment department, dormitory access, teachers’ attendance at get off work, and students’ attendance at get out of class.
Information management: realize the electronic and all-in-one card management of all management work on campus, such as campus card management, campus business management, financial charge management, educational administration management, library management, dormitory management, computer room billing management, water-saving control management, medical management, etc. .
4. Introduction of Runxi Express Bank-School All-in-One Card System
The Runxi Express Bank-School Card System is based on the school’s existing campus network. It uses the physical separation of bank cards and campus cards. Each application subsystem exists as independent modules and runs on the card platform. All relevant data And information is managed uniformly in the system to realize centralized storage and global sharing of data. The Runxi Express Bank-School Card System is no longer a simple consumer card, but a card system that integrates identity recognition, information management, financial services and other functions. It can truly realize “one card in hand, travel all over the campus.” “.
On the basis of the existing campus network, the Bank-School Card System uses advanced network technology to make all card-related data information independent of the existing campus network environment. At the same time, the internal data of the card is encrypted with three layers of 128-bit DES and the system encryption key. The dynamic storage method (a new encryption key is generated every time the system is started) ensures the security of data transmitted on the network. The whole system adopts a multi-layer application structure combining B/S and C/S.
1. Central server
One card platform operating system selection: Sun Solaris, SCO Unix
Platform database selection: Oracle10G database as a unified identity authentication shared library and a card data center storage soft platform
