Ubiquitous service - using RFID tag reader on a mobile terminal

This paper proposes a concept and requirements of ubiquitous service using a RFID tag reader on a mobile terminal. We assume that in the future, RFID tags will be attached to many objects in one´s surrounding environment and each object can be identified and semantically described. Under such an environment, a user can recognize the situation (context) and can decide a service to request.
