摘要

One settlement is made with multiple settlement means. Settlement means selected by the user, at least one of a settlement price allocated to each of the settlement means and a usage ratio allocated to each of the settlement means, and a total price to be settled are received from a site. Credit processing is performed for each price obtained by allocating the total price to the settlement means in accordance with the usage ratio or for each settlement price allocated to each of the settlement means. Sales determination processing is performed for each price obtained by allocating the total price to the settlement means in accordance with the usage ratio or for each settlement price allocated to each of the settlement means. A message indicating that the settlement has been finished is transmitted to the site. In the first settlement and second settlement, when all of the credit processing and the sales determination processing can be performed within the multi-settlement apparatus, the processing is performed within the multi-settlement apparatus, and when the credit processing and the sales determination processing cannot be performed within the multi-settlement apparatus, an external unit is requested to perform the processing.
