A remote monitoring system, for use in applications such as a vending machine, is disclosed. The remote monitoring system provides a user with a first code. The user transmits the first code to the entity that services the vending machine (or other installation). The first code not only provides the user with the opportunity to win a prize but also provides information about the status of the vending machine. The user then receives a second code that the user may enter into the machine to determine whether the user has won a prize but also to change the operation of the vending machine.
