Vending machine
A vending machine is an automated machine that dispenses items such as snacks, beverages, cigarettes, and lottery tickets to consumers after cash, a credit card, or other forms of payment are inserted into the machine or payment is otherwise made. The first modern vending machines were developed in England in the early 1880s and 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.
History
The earliest known reference to a vending machine is in the work of Hero of Alexandria, an engineer and mathematician in first-century Roman Egypt. His machine accepted a coin and then dispensed wine or holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened a valve which let some wine flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped the lever up and turned off the valve.Some early novelty vending machines featured a clucking chicken which dispensed a toy-filled egg.
Coin-operated machines that dispensed tobacco were being operated as early as 1615 in the taverns of England. The machines were portable and made of brass. An English bookseller, Richard Carlile, devised a newspaper dispensing machine for the dissemination of banned works in 1822. Simon Denham was awarded British Patent no. 706 for his stamp dispensing machine in 1867, the first fully automatic vending machine.
Modern vending machines
The first modern coin-operated vending machines were introduced in London, England, in the early 1880s, dispensing postcards. The machine was invented by Percival Everitt in 1883 and soon became a widespread feature at railway stations and post offices, dispensing envelopes, postcards, and notepaper. The Sweetmeat Automatic Delivery Company was founded in 1887 in England as the first company to deal primarily with installing and maintaining vending machines. Also at about that time in England, Dixon Henry Davies and inventor John Mensy Tourtel patented a coin-operated reading lamp for use on trains and founded the Railway Automatic Electric Light Syndicate, Ltd. The system ran off batteries and delivered 30 minutes of light for 1d., but was not a long-term success. Tourtel also invented a similarly coin-operated gas meter. In 1893, Stollwerck, a German chocolate manufacturer, was selling its chocolate in 15,000 vending machines. It set up separate companies in various territories to manufacture vending machines to sell not just chocolate, but cigarettes, matches, chewing gum, and soap products.The first vending machine in the U.S. was built in 1888 by the Thomas Adams Gum Company, selling gum on New York City train platforms. The idea of adding games to these machines as a further incentive to buy came in 1897 when the Pulver Manufacturing Company added small figures, which would move around whenever somebody bought some gum from their machines. This idea spawned a whole new type of mechanical device known as the "trade stimulators". Coin operated gas meters could be found in the United States, Australia and England. This style of meter can still be found in some countries.
Growth
The vending machine industry in the United States is a multi-billion dollar sector. In 2023, it was estimated to be worth $18.2 billion, with approximately 3 million machines generating an average monthly revenue of $525. However, this is an average, and the industry is trending toward more sophisticated and automated vending machines, particularly in North America.This trend is driven by the increasing demand for convenience and the development of advanced technologies. For instance, the hot food vending machine sector is valued at $4.8 billion and is seeing significant growth as robotics companies introduce automated solutions for dispensing pasta, burgers, and groceries. The broader fresh food vending segment is projected to reach $8 billion by 2029, offering consumers more options for nutritious and convenient meals and snacks.
Mechanisms
Internal communication in vending machines is typically based on the MDB standard, supported by National Automatic Merchandising Association and European Vending & Coffee Service Association.After payment has been tendered, a product may become available by:
- the machine releasing it, so that it falls in an open compartment at the bottom, or into a cup, either released first, or put in by the customer, or
- the unlocking of a door, drawer, or turning of a knob.

The main example of a vending machine giving access to all merchandise after paying for one item is a newspaper vending machine found mainly in the U.S. and Canada. It contains a pile of identical newspapers. After a sale the door automatically returns to a locked position. A customer could open the box and take all of the newspapers or, for the benefit of other customers, leave all of the newspapers outside of the box, slowly return the door to an unlatched position, or block the door from fully closing, each of which are frequently discouraged, sometimes by a security clamp. The success of such machines is predicated on the assumption that the customer will be honest, and need only one copy.
Common vending machines
Change machine
A change machine is a vending machine that accepts large denominations of currency and returns an equal amount of currency in smaller bills or coins. Typically these machines are used to provide coins in exchange for paper currency, in which case they are also often known as bill changers.Cigarette vending
In the past, cigarettes were commonly sold in the United States through these machines, but this is increasingly rare due to concerns about underage buyers. Sometimes a pass has to be inserted in the machine to prove one's age before a purchase can be made. In the United Kingdom, legislation banning them outright came into effect on 1 October 2011. In Germany, Austria, Italy, the Czech Republic, and Japan, cigarette machines are still common.Since 2007, however, age verification has been mandatory in Germany and Italy – buyers must be 18 or over. The various machines installed in pubs and cafés, other publicly accessible buildings, and on the street accept one or more of the following as proof of age: the buyer's identity card, bank debit card, or European Union driver's license. In Japan, age verification has been mandatory since 1 July 2008 via the Taspo card, issued only to persons aged 20 or over. The Taspo card uses RFID, stores monetary value, and is contactless.
Birth control and condom vending machines
A birth control machine is a vending machine for the sale of birth control, such as condoms or emergency contraception. Condom machines are often placed in public toilets, subway stations, airports, or schools as a public health measure to promote safe sex. Many pharmacies also keep one outside, for after-hours access. Rare examples exist that dispense female condoms or the morning after pill.Food and snack vending machines
Various types of food and snack vending machines exist in the world. Food vending machines that provide shelf-stable foods such as chips, cookies, cakes, and other such snacks are common. Some food vending machines are refrigerated or frozen, such as for chilled soft drinks and ice cream treats, and some machines provide hot food.Some unique food vending machines exist that are specialized and less common, such as the French fry vending machine and hot pizza vending machines, such as Let's Pizza. The Beverly Hills Caviar Automated Boutique dispenses frozen caviar and other high-end foods.
Bulk candy and gumball vending
The profit margins in the bulk candy business can be quite high – gumballs, for instance, can be purchased in bulk for around 2 cents per piece and sold for 25 cents in gumball machines in the U.S., and other countries. Gumballs and candy have a relatively long shelf life, enabling vending machine operators to manage many machines without too much time or cost involved. In addition, the machines are typically inexpensive compared to soft drink or snack machines, which often require power and sometimes refrigeration to work. Many operators donate a percentage of the profits to charity so that locations will allow them to place the machines for free.Bulk vending may be a more practical choice than soft drink/snack vending for an individual who also works a full-time job, since the restaurants, retail stores, and other locations suitable for bulk vending may be more likely to be open during the evening and on weekends than venues such as offices that host soft drink and snack machines.
The bulk vending machines of today provide many different vending choices with the use of adjustable gumball and candy wheels. Adjustable gumball wheels allow an operator to not only offer the traditional 1-inch gumball, but they can also vend larger gumballs, and non-edible items such as toy capsules and bouncy balls. Adjustable candy wheels allow an operator to offer a variety of pressed candies, jelly candy, chocolates and even nuts.
