<p><P>PROBLEM TO BE SOLVED: To provide a wireless tag communication device and wireless tag communication system which can rapidly check the existence of a plurality of wireless tags which have been listed, in advance. <P>SOLUTION: The wireless tag communication system includes a communication control unit 72, which selectively establishes a first communication mode in which information is communicated between all the radio tags 14 included in a list which defines the predetermined wireless tags 14, as communication objects, and a second communication mode in which at least one of the wireless tags 14, corresponding to the specified identifier is used as a communication object and information is communicated with the wireless tag 14; and a switching judgment unit 71, which determines switching between the first communication mode and the second communication mode according to a predetermined parameter from a predetermined switching condition. Thus, in a communication for verifying the existence of the wireless tags 14 which have been listed, in advance, since communication can be specified by specifying an identifier based on the check process, communication can be performed effectively with an unidentified wireless tag 14. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
