Abstract: A coin change device with automatic readjustment and classification to match with the transaction/retail (wholesale) account closing device such as a cash register for use comprises a coin readjustment and dispense module, a recognition module, a storage module, and a dispense/retrieve module, wherein more than one coin can be thrown in said coin readjustment and dispense module at one time to perform automatic coin recognition, calculation, storage and change-making action through said coin change device with automatic readjustment and classification, thereby to exempt required manual counting and change-making operation by the register and thus reducing chances of possible errors in receiving and dispensing the monetary amount as well as saving the time required for daily coins counting and adjustment.
