PROBLEM TO BE SOLVED: To provide a game machine monitoring system capable of monitoring fraudulent acts more reliably and efficiently and a game machine equipped with the game machine monitoring system. SOLUTION: If a master card is taken out of a card holder after radio frequency identification (RFID) communication for verification, an R/W (reader/writer) unit stores identification information, included in an initial reflected wave from a monitoring tag to a call wave from a verification antenna, as third identification information in a RAM in the monitoring RFID communication performed between the monitoring tag and a monitoring antenna later. The third identification information stored in the RAM is compared with first identification information stored in an EEPROM (electrically erasable and programmable read-only memory). If different identification information is found as the result of the comparison, the finding of the different identification information is transmitted to a station or the like and is reported at the station. Then, verification signals transmitted from the station cause the R/W unit to overwrite the identification information stored in the RAM on the first identification information in the EEPROM.
