Abstract
A tag access control system for controlling data communication between a plurality of reader/writers respectively having a plurality of antennas and one or more IC tags moving sequentially through communication ranges of the plurality of antennas includes a storing portion for storing movement information and reader/writer information, a command accepting portion for accepting a command, a dividing portion for generating a plurality of divided commands from the command, a detecting portion for detecting the IC tag located within the communication range of the antenna in one reader/writer of the plurality of reader/writers, a job controlling portion for sequentially assigning the plurality of reader/writers the plurality of divided commands according to the movement information and the reader/writer information, and a returning portion for returning a result of processing the command. In this way, the tag access control system can improve a success rate of reading data from and writing data in a plurality of IC tags without lowering a moving velocity of articles.
