A money processing system includes: a money processing machine including a processing machine communication section and a processing machine controller; a first terminal including a first reception section, a first communication section, and a first controller; and a second terminal including a second reception section, a second communication section, and a second controller. The first terminal is a mobile communication terminal. The processing machine communication section transmits state information indicating a state of the money processing machine. In a case where the first reception section receives a consent operation to handle an error in the money processing machine, the first communication section transmits consent information. The error in the money processing machine is indicated by the state information. The second controller causes the second communication section to receive the consent information.
