In order to improve efficiency of an operation of a cash handling system and reduce the labor required for the operation, a POS register receives an input of a cash-out amount, and an input of a charge amount. The POS register reads a debit card ID from a debit card, and transmits a settlement request including the debit card ID and a settlement amount to a management server. Upon receiving the settlement request, the management server withdraws the settlement amount from an account, and transmits a settlement permission to the POS register. Upon receiving the settlement permission from the management server, the POS register performs charge of electronic money, and transmits a dispensing instruction for the cash-out amount to a change machine. The change machine receives the dispensing instruction and dispenses cash.
