Study of Integrating RFID Middleware with Enterprise Applications Based on SOA

Radio frequency identification (RFID) is a form of automatic identification and data capture (AIDC) technology applicable to various areas. The integration of RFID equipments and enterprises applications (e.g. ERP, SCM) is one of the key problems in the development of RFID technology. RFID middleware turns out to be a good solution, which in practice has accelerated the adoption of RFID technology. A SOA-based RFID application integration project is described. In the project, enterprise applications can invoke the services provided by RFID middleware across services interface layer. In particular, for code reuse, some common functions, such as SOAP communication, data exchange mechanism, are built into a component called service proxy. By inheriting the proxy, other system components (e.g. inbound and outbound management) can have these functions. The project is an effort of integrating an RFID middleware with a warehouse management system (WMS).
