RADIO TAG READER/WRITER, COMMUNICATION DEVICE AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the communication between an RFID reader/writer 200 and an RFID tag 700 by devising the antenna 220 of the RFID reader/writer 200.

SOLUTION: A radio tag reader/writer includes a second casing 240 accommodating the antenna 200 for communicating with the RFID tag 700, and a first casing 210 accommodating an RFID reader/writer 230 for writing information in the RFID tag 700 or reading information from the RFID tag 700. The angle formed by the antenna 220 and the RFID reader/writer 230 is the angle at which the electric wave sending/receiving surface of the antenna 220 and the sticking surface of the RFID tag 700 are opposite each other, at least during communication with the RFID tag 700.
