<p>There is provided a radio communication device capable of accurately selecting an object RF-tag to be processed and a non-object RF-tag not to be processed. An RF-tag inquiry unit inquires for tag identification information to an RF-tag by radio communication. A radio field intensity detecting unit detects a radio field intensity of a response radiowave returned from the RF-tag, and a radio field intensity determining unit determines whether or not this radio field intensity is equal to or greater than a threshold. An execution control unit executes a prescribed process applying to the RF-tag whose radio field intensity is determined to be equal to or greater than the threshold. A first radio field intensity determining unit determines a first radio field intensity using the radio field intensity of the radiowave responded from the RF-tag that has been determined to be an object to which a prescribed process is applied, while a second radio field intensity determining unit determines a second radio field intensity using the radio field intensity of the radiowave responded from the RF-tag that has been determined to be non-object not to be processed. A threshold update unit calculates a new threshold using the first radio field intensity and second radio field intensity.</p> |
