Abstract
It is possible to provide a tag communication device, a tag communication system, and a tag communication method which can secure an optimal communication region even when an antenna installation environment or a peripheral environment changes. A tag A is arranged in a preset communication region while a tag B is arranged outside the communication region. A reader/writer () repeatedly scans a radio beam M emitted from a scan antenna () and then controls the radio beam so that all the tags A can be read while no tag B can be read according to the ID which has been read.
