The Design Of ATM Application System Based WOSA/XFS Standard

With the development of the constructing of the financial computerizing of our country, ATM (ATM Teller Machine) is more and more popular with the people by its convenience and shortcut.. In order to improve self-services, manufacturers and delegates join together to make some standards and protocols, WOSA/XFS is one of those. It provides seamless integration for windows based client application and servers. The internet applications of ATM client which supported the WOSA/XFS standard interface is independent of the hardware platform. A unite software platform of ATM client can run to different device of ATM which supported the WOSA/XFS standard.For the content of this article, the article context is introduce firstly to account for the development of the current computer technology and ATM software, and explain order and signification of this article . The second part introduce the distributing structure of application system, the object oriented technology, the mechanism of message response, dynamic linked library technology, multithreading which reuse the software and easy to add function. The third part is about the ATM model to account for the concept and framework of the WOSA/XFS, how to use the logical device of XFS. As the base of above, the ATM software is easy to expand and integrate. And make full use of software which is used. The fourth part introduce the modules and interaction in the ATMC software design and implement the design of detailed function of truncation module, communication module, data transition module, etc. ISO8583 international information financial message was used in the transition of ATM terminal, the transition of the form of communication message was implemented by the data transition module.At last, the software design of ATM system base the WOSA/XFS standard to implement the detailed function, which is ATM withdraw money, transfer account, change password and query.
