To record change in a card and allot change for next-time purchase of an article without generating any actual change coins as change generated when an article is purchased or to request payment only in cash without any article purchase and to print it on a card.
The total of the amount of unpaid change as the change generated when the article is purchased is recorded as the remaining accumulated amount of unpaid change on a card exclusively for change or change/point card and when a customer who buys an article next time makes a request to allot the whole or part of the accumulated amount of unpaid change for the purchase, the requested amount is subtracted from the accumulated amount of unpaid change recorded on the card exclusively for change or change/point card while the requested amount is paid. In the figure, 701 is a preprint area and 702 is a print recording area.
