Abstract: A touchless vend system includes a first processor and a second processor, each within a vending machine and communicably coupled to one another. The first processor can receive a signal representing a product selection, associated with a product in the vending machine, from a mobile device. The first processor can transmit a payment authorization to a controller of the vending machine, and transmit the signal representing the product selection to the second processor. The second processor receives the signal representing the product selection from the first processor, converts the signal representing the product selection into an electronic signal based on a make, a model, and version information of the vend machine, and sends the electronic signal to the controller to cause vending of the product.
