ABSTRACT:
A vending control system for sequentially carrying out a first and second operation in order to insure that the selected article is in fact vendible and that the correct amount of change is provided. During the first operation, the amount of deposited coins is compared with the vend price of all articles in order to determine which articles are vendible, and article selection switches corresponding to the vendible articles are enabled. And during the second operation, the amount of deposited coins is compared with the vend price of an article selected by operation of the corresponding article selection switch, in order to confirm that the selected article is in fact vendible and to insure that the proper amount of change is provided.
