An object of the present invention is to provide a currency handling system which makes it possible to decrease a risk of dealing with foreign currency at the time of the occurrence of a communication error in a case in which a currency reading device capable of accepting a variety of currencies including a foreign currency is used while the currency handling system is connected to a management server through a communication line. A currency handling system 100 is connected to a casino management system 2 through a network 3, and includes a currency reading device 201 which is capable of accepting a variety of currencies and a PTS terminal 700. The PTS terminal 700 causes a process which limits usage of a foreign currency but allows usage of a local currency in the currency reading device 201 to be performed in a case (offline state) in which an error occurs in communication with the casino management system 2.
