A transmitter sends signals such as a command to each of the plural kinds of noncontact information carriers. A receiver receives signals such as a response from each of the plural kinds of noncontact information carriers. A memory stores information on at least one kind of the plural kinds of noncontact information carriers with which the noncontact reader/writer has communicated. In communication processing, based upon the information, a controller determines a priority order on the kinds of the plural kinds of noncontact information carriers with which the noncontact reader/writer communicates and caries out the communication processing. The above-mentioned information includes the kinds of the noncontact information carriers or a number of communication times with respect to each of the kinds. <IMAGE>
