Many sensors providing situation data will be in everywhere under the ubiquitous environment. The current RFID system should be extended to recognize and use situation information from the sensors. This study proposes RFID system architectures that are suitable for the ubiquitous environment. This study applies the situation awareness concept to and extends the current RFID system architecture to be able to adapt to the environment. The key components include an inference engine, use policy and definition language. The proposed architecture is named SA-RFID system architecture and can provides the ability to recognize, analyze and use with situation information from sensors under the ubiquitous computing environment. As a result, the usability of the current RFID system is improved and its application increases.
