  • Patent number: 7073683
    Abstract: A sensor for detecting and signaling whether a requested product is successfully vended is placed in a vending machine. The sensor determines whether a requested product passes through a defined “vend area” within a predetermined time interval after the customer's request for the product. If the product does pass through the vend area within the time interval, a successful transaction is signaled and the sensor is reset. However, if no signal is received within the time interval, a procedure to remedy the failed transaction is executed. This procedure includes refunding the customer's money, crediting the customer's next transaction, or vending a similar product.
