This invention provides a currency
processing system that simplifies the process of adjusting the threshold value of the identification unit for each region in order to improve the
acceptance rate of inserted currency in multiple vending machines installed in each region. [Solution] This currency
processing system 100 comprises multiple vending machines 10 installed in each region, and a management
server 20 connected to each of the vending machines 10. The vending
machine 10 includes a banknote
processing unit 1 and a
coin processing unit 2, each having identification units 1b and 2b for identifying currency. The management
server 20 adjusts the thresholds of the multiple identification units 1b and 2b in each region based on currency identification information that identifies genuine and counterfeit currency in the vending machines 10 in each region. The banknote processing unit 1 and the
coin processing unit 2 identify the inserted currency based on the thresholds adjusted for each region.
