Abstract

In a vending machine selling products and services without human attendance, at a point of sale, a discounting service is provided to each purchaser according to the frequency-of-purchase record of respective purchasers. A microcomputer 2 collects electronic money corresponding to prices of products purchased from a product purchaser's IC card 8 inserted into an IC card reading apparatus 1 by each purchaser, and transfers it to a product seller's IC card. Further, on this occasion, the number of times of purchase corresponding to a personal ID stored in a product purchaser's IC card 8 is stored on the number of-times of purchase list of the memory unit 3, and a personal ID is registered on the personal ID list of a memory unit 3. When the number of times of purchase exceeds the reference number of times of purchase, when collecting e-money from the product purchaser's ID card 8 whose personal ID is registered on the personal ID list, the microcomputer 2 applies a discounted price as a price for the purchased product.
