Vending machine A vending machine is an automated machine that provides items such as snacks, beverages, alcohol, cigarettes and lottery tickets to consumers after money or a credit card is inserted into the machine. The first modern vending machines were developed in England in the early 1880s that dispensed postcards. Vending machines exist in many countries, and in more recent times, specialized vending machines that provide less common products compared to traditional vending machine items have been created and provided to consumers.
