When a tag selector 30 receives a plurality of RFID tag IDs detected by an RFID tag reader 10 , by a tag ID receiving part 31 , it acquires nonspecificities corresponding to these RFID tag IDs from an attribute information DB 41 . The tag selector 30 selects an RFID tag ID with a nonspecificity smaller than a predetermined selected tag threshold by a tag ID selecting part 33 and notifies a service determining device 50 of it. A nonspecificity is an index indicating a diversity of use of an article to which a corresponding RFID tag is attached. Therefore, the service determining device 50 determines a service to be provided for the user, based on the RFID tag ID with the low nonspecificity value, whereby it becomes feasible to promptly provide the service very likely desired by the user.
