Patent ID: 10796538

Abstract:
One object is to efficiently identify number of transactions that can be performed by using an inventory amount of money inside a change machine and to improve the business efficiency. A POS register (290) transmits a total amount request to a change machine (200) connected thereto (Step S11). Upon receiving the total amount request from the POS register (290), a change machine (200) transmits to the POS register (290) a total amount of money that can be dispensed as change and that is calculated based on an inventory amount of one or more predetermined denominations (Step S12). The POS register (290) receives the total amount from the change machine (200) (Step S13) and calculates number of transactions for which the change can be dispensed by calculating how many times is the total amount of the maximum change amount (JPY9, 999) for one transaction (Step S14). The POS register (290) informs the salesclerk of the calculated number of transactions by displaying and the like. Therefore, the salesclerk can confirm the number of transactions and can use this information as a factor to determine a timing of replenishing the change.
