Before using the all-in-one card, in addition to the necessary student ID card for everyone, a large number of different types of cards, cards and tickets were used in the school, such as library card, canteen meal card or meal ticket, computer card, time card, etc. All kinds of certificates, cards and tickets coexist at the same time, which makes the management decentralized and inconvenient to use. Even the cards with various automatic identification technologies can not be used universally due to the wide variety of machines, resulting in complex use procedures, and there is no unified management in the school, which cannot meet the construction and development requirements of campus digitization and informatization.

The implementation of campus "all-in-one card" can not only reduce the problems of a large number of cards, certificates and bills, complicated and inconvenient procedures, but also add personal identity authentication information to the "all-in-one card", so that the "all-in-one card" card can not only be used as a card for payment, but also as a certificate for identity recognition. In this way, all departments can be managed in a unified way, saving time, improving efficiency, and making the campus have a modern management level.

At present, the campus "all in one card" system is implemented, and the IC card reading and writing technology is highly mature. The non-contact IC card used has superior performance, and the storage structure fully meets the needs of "all in one card". Making full use of the multiple functions of "all in one card" can save investment and optimize management benefits.

Contactless IC card will give full play to the role of existing resources, complete consumption management, access control and attendance management, library management, computer management, etc., improve work efficiency, eliminate the cost of printing all kinds of valid certificates and bills, and save human and financial resources for the campus. The use of IC card as campus e-wallet and ID card can prevent the forgery of campus meal tickets and certificates. In addition, schools can save money by recycling and reusing IC card.
