Research and Realization of the Bank Self-service Terminal Based on XFS Standard

This paper discusses adding a new logic processing module which is in line with the WOSA/XFS standard to the existing self-service terminal. In this module, the mapping relationship of the SP (service provider) and service call function have been realized because the use of reflection mechanisms, thereby ensuring that the application function has nothing to do with the hardware devices. All that have effectively raise the scalability and manageability of the self-service system to expand, delete and update.
