Abstract: A method and system to access vending machines via a touch-free user interface using a personal electronic device (PED) are described. For each vending session, a unique dynamic tag is generated and presented on a vending machine to be read via a camera. The tag is forwarded by the PED to a remote servicer, which accesses a remote database to determine real-time inventory of the vending machine. This inventory list is transmitted back to the PED for display to a user. The user selects a product from inventory using her PED. This selection is sent to the server, which then transmits instructions to the vending machine to dispense the selected product. The method is free of a requirement for the user to download an app. Security and payment are assured by the use of a unique dynamic tag for each vending session, displayed on or by the vending machine.
