Reader for RFID tag for near-field wireless communication and near-field wireless communication system

摘要

In a reader for an RFID tag for near-field wireless communication, an antenna selection switch includes a plurality of antennae arranged with an extent within a predetermined range for transmitting and receiving data to and from an RFID tag, and selects one antenna to be used for transmission and reception of data from among the plurality of antennae. A detection part acquires, when a carrier wave transmitted from the RFID tag is received by any of the plurality of antennae, information indicative of an antenna selected by the antenna selection switch under the control of an antenna changeover controlling part.
