AbstractAbstract Abstract Abstract Although the form of financial IC card industry is in a variety of applications，the form of the financial IC cards in public transportation，cafeteria,parking and other industry units small electronic cash offiine is most typical and widespread consumption．No matter what form of industrial applications，”liquidation”is always aIl essential，but the key link basis．Expanding the application must be addressed that how to achieve acquirer(often the issuers)and industry quick docking unit system to meet the IC card electronic cash offiine consumer transactions small clearing liquidation industry needs． Based on the analysis of system requirements，this thesisuses Oracle Pro}C technology and Oracle 1 09 database technology to design and implement each functional module of the system．IC card electronic cashindustry applications settlement system is divided into six subsystems，i．e．，the data transfer subsystem，data checking subsystem，data loading subsystem，clearing clearing subsystem，business management subsystem and system maintenance subsystem． Also，the design of the various subsystems is from the flrewall，intrusion detection and access control three aspects of the system security design．System presentation layer made use of customizable page components to complete，to control the content of the page by component packaging properties，methods and events to meet the business requirements．Intermediate operation logic is integrated use of the C ++and object-oriented programming language Java to achieve．Each subsystem is in accordance with the actual business needs，designing a clear logical model，and it designs the appropriate interface for the presentation layer and data access layer,for system data exchange plays a connecting role．Data is stored using a relational database Oracle l Og，and in the design and implementation in order to improve system performance when using the partition table and other database optimization strategies to optimize th
