This banknote processing device (100) is provided with a hopper (2) which receives banknotes, an identification unit (3) which reads the serial numbers of the banknotes received by the hopper (2), a database (1202) which stores the serial numbers read by the identification unit (3), and a control unit (120) which controls processing of the banknotes. The control unit (120) inspects the serial numbers stored in the database (1202) for duplicate serial numbers, and if there are duplicate serial numbers, detects that processing was performed redundantly for the banknote corresponding to the duplicate serial numbers. |
