  • Patent number: 6279718
    Abstract: A vending or merchandising machine is provided which includes a bulk-loaded coin hopper for providing change to a user of the machine. The vending machine may be operable in a change mode, wherein change is dispensed from the bulk loaded hopper in an amount equivalent to the amount of credit input into the machine by user, or a vending mode, where a user may select an item to be purchased, and receive the item and change in an amount equal to the input amount less the purchase price of the item. Preferably, the vending machine automatically switches to the change mode in response to an input threshold amount being inserted into the vending machine. Preferably, the vending machine further may be selectively switched to the change mode in response to a user input on a keypad or the like on the merchandising machine.
