In the product exhibition hall, we showed the sorting functions of the fitness sorting machine, including ATM sort, fitness sort, unfit sort, orientation sort, face sort, version sort and denomination sort, as well as the counterfeit banknote detection, via CIS image, IR and MG. We mainly helped customers solve two problems: the SUPER counterfeit detection and the too many rejecting of dirty wet banknotes. The engineers conducted on-site debugging and teaching. The customers were deeply shocked by the high performance of the machine, The customer said that our machine will replace other brands in the near future.
