To provide a banknote monitoring device capable of detecting that a form of a banknote has been changed.SOLUTION: A banknote monitoring device 1 includes a receiving part (terminal device 3) that receives information transmitted by a plurality of banknote processing device that process a banknote with a serial number, and a control part that acquires recognition rate information of the serial number based on a predetermined number or more pieces of information. The control part acquires a change amount of the recognition rate information per predetermined time, and outputs information indicating that the absolute value of the change amount is greater than a predetermined threshold value when the absolute value of the change amount is greater than the predetermined threshold value.SELECTED DRAWING: Figure 1 【課題】紙幣の態様が変更されたことを検知できる紙幣監視装置を提供する。【解決手段】紙幣監視装置１は、記番号が付されている紙幣を処理する複数の紙幣処理装置が送信する情報を受信する受信部（端末装置３）と、所定数以上の情報に基づいた記番号の認識率情報を取得する制御部と、を有する。制御部は、所定時間当たりにおける前記認識率情報の変化量を取得し、変化量の絶対値が所定閾値より大きい場合、変化量の絶対値が所定閾値より大きいことを示す情報を出力する。【選択図】図１
