A vending machine is a self-service device that dispenses various products, such as snacks, beverages, and sometimes even personal care items. Users can select their desired item by pressing buttons or touching a screen, and the machine automatically delivers the product after payment is made, typically through coins, bills, or credit cards. These machines are commonly found in public places like schools, offices, and shopping centers. They offer convenience by providing quick access to food and drinks without the need for a cashier. Some modern vending machines even include features like touchless payment options and refrigerated compartments for perishable items.
