Numerous industry and retail companies are currently faced with the challenge of integrating RFID technology with their existing IT landscapes. Against this background, this article provides an overview of the structure of RFID systems, their coupling with corporate application systems as well as associated integration problems and solution concepts based on an analysis of various real-world projects. We identify four different project types, each of them characterised by a different emphasis on certain problem situations. Another focus of the article is on the role of current standards, their limitations and potentials. It becomes evident that hardware components and numbering schemes are suitable for harmonisation due to their general applicability whereas other aspects of RFID systems integration must be considered to a larger extent from the respective process to be supported.
