The normal use of IC cards requires the support of an information management system with IC cards as the basic means, that is, IC card application systems. Through this system, the card can provide users with information, provide services to users, and ensure the safety of users using the card. It is generally believed that the IC card application system should include the following three aspects:
(1) Hardware technology. The hardware technology includes IC card chip technology, IC card module technology, IC card assembly technology, IC card testing technology, IC card base technology, IC card reading and writing equipment development technology, etc.
(2) Software technology. Software technology includes system software and application software. System software includes computer network system, communication system, as well as the development of the chip operating system (COS) in the card, the development of IC card reading and writing tools and various high-level language interface functions, storage management, cryptography, security solutions, etc. ; The application software includes the card issuing interface of COS and the application software related to the application management information system [1].
(3) Business analysis of IC card applications. The business analysis of the IC card application field should and must be provided by the relevant business departments that develop the IC card application system. Like the business analysis of the management information system, its depth and breadth directly affect the success or failure of the IC card application system.
(4) Sales terminal equipment. A point of sale (POS) is a credit card authorization terminal set up by a bank at a commercial outlet or a special merchant. In practical application, a cash register is generally used as a terminal to be connected to a host computer, and commodity information is entered into the computer by means of a photoelectric reading device. When a commodity with a barcode is scanned through the checkout station, the information represented by the commodity barcode is read to the computer, and the computer queries the name and price of the commodity from the database file, and prints a receipt through data processing. The POS system was first used in the retail industry, and then gradually expanded to other service industries such as finance and hotels. The scope of using the POS system has also expanded from within the enterprise to the entire supply chain.
