PROBLEM TO BE SOLVED: To provide a RFID system and a toy which may improve position detection precision on a tablet by leaps and bounds. SOLUTION: The RFID system has a reader/writer and a transceiver antenna, a RFID tag which sends one's own authentication information signal in response to an electromagnetic field or an electric wave radiated from the transceiver antenna. The transceiver antenna consists of an antenna array in which two or more independent rectangle metal loop lines are arranged in parallel at a predetermined mutual interval.
