TAG COMMUNICATION DEVICE, TAG COMMUNICATION SYSTEM, AND TAG COMMUNICATION METHOD |
摘要 |
<p>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 (3) repeatedly scans a radio beam M emitted from a scan antenna (4) 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.</p> |
