Abstract

Radio Frequency Identification (RFID) middleware is a new breed of software system which facilitates data communication between automatic identification equipments like RFID readers and enterprise applications. It provides a distributed environment to process the data coming from tags, filter and then deliver it to a variety of backend applications via various communication protocols including web services. In this paper, we demonstrate the implementation of the RFID middleware system that is not only compatible with EPCglobal ALE (Application Level Events) specification but also provides various types of RFID readers spanning from passive readers to active readers. Overall functional components of the middleware software as well as the system framework are illustrated.
