Abstract

Money amount data and necessary discrimination data are recorded on a card and a card reader can read and write data on this card. A discarding circuit discards a money amount which is less than a money amount digit of a minimum denomination coin which can be handled from the money amount data read from the card. Money amount data left after discarding is added to a money amount of deposited coins and result of the addition is compared with a vend price for judgement as to whether vending is possible or not. Vend control of an article is made on the basis of this judgement. Discount is made from a predetermined vend price of the vended article. The vend price after the discount is subtracted from the money amount data read from the card by the card reader and the balance is caused to be written in the card by the card reader.
