EXTENDED KEYPAD FOR CONTROLLING VENDING MACHINE OPERATION

摘要

A user selection keypad allows at least some functionality of vending machine programming configured for a touchscreen display to be utilized without the touchscreen. In addition to character-labeled keys and other standard functionality (such as keys to confirm or cancel an entry), the keypad includes: a shopping cart key that, when actuated, invokes aggregation of multiple product selections for a single vend transaction; and an information key that, when actuated, allows the customer to request display of nutritional information for a currently selected product and/or context-sensitive help information.
