Abstract:
Since its introduction, working as a big warehouse has become one of main tasks of the Internet. Today, it doesn’t seem surprisingly to buy anything on-line, and therefore, e-payment systems are booming. Users are confronted with them in a wide range of diversity, which might lead into some confusion. But if that’s not all, new payment systems are steadily flooding the market, focussing on new segments. This process led into a splitting of the market, where new suppliers are jumping on the wagon with their protected softwares.
The goal of this thesis is to bring step by step this seemingly confusing multitude of payment systems, currently offered on the market, into one image.
Part one will look for a way to develop a classification scheme, in which payment systems can be systemized, to give the reader an overall view. Later criteria and qualifications which are essential for the realization of a payment system are going to be crystallized. At the end of part one, every payment system available on the Austrian and German market at publishing date of this thesis will be checked with the use of analysis and criticism by finding an evaluation about how well every criterion is realized within the development process of the specific software.
The final part of the thesis will be focussing on the illustration of every analyzed payment system as a workflow model. Its intention will be to provide a summary for all the activities and their related background processes which are necessary for business processes. In the sequel it should be made possible to integrate these diagrams into an existing enterprise model as items from a toolbox within a development tool. Finally every noticed payment system will be profiled. These profiles should function as a set of rules to assess every payment system within a business model. The risks relating by integrating a payment system, which is unqualified for a specific task, should become avoidable right at the start.
