This gift certificate has information recorded thereon for identifying a total face value vendible by the gift certificate and a predetermined base amount equal to or smaller than the total face value. The information recorded on a deposited gift certificate is read by a reading device. A validation device validates the total face value and the base amount of the deposited gift certificate in response to the read information. A vending permission judgement device prohibits, in reponse to an output of the validation device, at least vending of an article to which a vend price below the base amount has been assigned. By virtue of this arrangement, a purchaser of an article from a vending machine by using a gift certificate is not forced to make purchase of the entire total face value but has only to make purchase above the base amount in which case a change preferably is paid out.
