An automatic vending system in which cards having predetermined monetary values accorded thereto are utilized to purchase an article or service. The system comprises, in combination, a card issuance control device, an article dispensation control device and a card-to-cash conversion control device. By presenting a desired amount of money to the system, the customer may obtain a card having the corresponding monetary value accorded thereto. The owner of a card may obtain an article or service by using the card in the system. When a purchase has been made, the price of the article purchased is subtracted from the monetary value the card had prior to the purchase, and the resultant new monetary value is written on the card in place of the original monetary value thereof. The owner of a card may at any time have the card converted to cash corresponding to the monetary value the card then has.
