Vending machines dispense products such as snacks, sodas, bottled water and juices to people who insert money into them. Most modern vending machines are able to provide change for paper money; however some vending machines require change only. Vending machines are usually rented by a business to generate additional profit and are frequently stocked by the company that rents them out. The products stocked in vending machines may change from time to time as different products become available. Companies that rent out vending machines often keep statistics as to popular items at particular locations and may alter the items in the vending machines to match the need.
