RFID Interoperability in the Spotlight

Overview: The common definition of Interoperability is that of "the functional testing of a product against another product according to a set of test specifications." Unfortunately, this definition does not meet RFID requirements. The primary reason for it is that RFID implementations consist of a system of hardware, data, and software. RFID tags communicate with readers and exchange data using air interface protocols. Software facilities communications between readers, RFID middleware, and enterprise applications such as ERPs and WMS. Any component of the RFID system may cause interoperability issues that could affect implementation.
