There are eight main types of vending machines a workplace or building is likely to be offered: snack, cold drink, combo, frozen, hot drink, fresh food, smart cooler and micro market. They differ in what they sell, how much space and power they need, and how many people a site needs before an operator will place one.
This is the overview. If you'd rather answer a few questions and get a suggestion for your site, use the vending machine type chooser.
The eight types at a glance
| Type | Sells | Refrigerated | Best for |
|---|---|---|---|
| Snack machine | Chips, bars, candy, pastries | No | Most sites; the lowest power and the smallest bar to entry |
| Cold drink machine | Bottled and canned drinks | Yes | Gyms, warehouses, any site with long shifts |
| Combo machine | Snacks and drinks in one cabinet | Part of it | Smaller sites, or where there's room for one machine |
| Frozen machine | Ice cream, frozen meals | Freezer | Large sites with a microwave nearby, campuses, hospitals |
| Hot drink machine | Coffee, tea, hot chocolate | No (it heats) | Sites with no café, night shifts |
| Fresh food machine | Sandwiches, salads, meals | Yes | Larger sites with long hours and no cafeteria |
| Smart cooler | Fresh and packaged items, open-door | Yes | Lobbies and break rooms with steady, known users |
| Micro market | Open shelves, coolers and a self-checkout kiosk | Partly | Larger workplaces that want a small store |
Snack machines
The classic spiral machine. It needs no refrigeration, only power for lights, the payment system and the vend motors, so it's the cheapest machine to run and the easiest to place. Most operators can put one in a site that wouldn't support anything else.
Cold drink machines
Drink machines are regulated for energy use. In the US, federal rules sort refrigerated drink machines into classes: Class A has 25% or more of its front transparent (glass-front), Class B is everything else, usually the solid-front, can-and-bottle style. A machine made since January 8, 2019 must stay under a daily energy limit set by class and refrigerated volume; for Class A it's 0.052 × volume + 2.43 kWh a day. Canada regulates the same machines under its Energy Efficiency Regulations, for machines made from the same date.
What that means for a host: a glass-front machine shows the products and tends to sell better; a solid-front one uses a little less power. Either way, the power cost is modest; our guide to getting a machine works through the monthly number.
Combo machines
A combo machine puts drinks and snacks in one cabinet. US energy rules define it precisely: two or more compartments separated by a solid partition, at least one refrigerated and at least one not. It has its own energy limit (Combination A and B, again split by how much of the front is glass). Combos are the usual answer for a site that has room, power and demand for exactly one machine.
Frozen and hot drink machines
Frozen machines sell ice cream and frozen meals. They draw more power and need people who'll use them, so they show up at hospitals, campuses and large plants with a microwave in the break room.
Hot drink machines brew coffee, tea and hot chocolate. They suit night shifts and sites with no café. Where buyers choose options like milk or sugar, the US calorie rule asks covered operators to show calories per option or for the final drink.
Fresh food machines
Sandwiches, salads and full meals, kept cold and sold through a glass-front machine or a lift system. Fresh food has short shelf life, so the operator needs enough daily sales to restock often without waste. Expect local food-handling rules to apply; our BC fresh food rules post shows one province's version.
Smart coolers
A smart cooler is a refrigerated cabinet with a locked door that opens when you tap a card or phone. You take what you want, close the door, and weight sensors or cameras charge you. It holds more variety than a spiral machine and works well in lobbies and break rooms where the same people come back. Our smart cooler vs vending machine comparison goes deeper, with a strata lobby as the example.
Micro markets
A micro market is a small self-serve store: open shelves, a few coolers and a self-checkout kiosk. It's the biggest step up, with the widest menu and the most space, and it generally needs a larger workplace with a fairly closed population. We compare the two head to head in micro market vs vending machine for an office.
Rules that apply to every type
- Calories (US): an operator of 20 or more food vending machines must show calories for items whose Nutrition Facts label can't be seen before purchase, on a sign or screen next to the item. Below 20 machines, operators can opt in by registering with the FDA.
- The machine belongs to the operator: stocking, repairs, card processing and sales tax are on their side, whatever the type.
- Payment: most new machines take cards and phones. Whether to also take cash is a choice; see card-only vending and refunds.
How to choose
Start from your site, not the machine: how many people are there, for how many hours, and how far the nearest food is. A site with 20 to 40 people usually starts with a snack or combo machine. Add a drink machine when there's demand and power. Fresh food, smart coolers and micro markets come in at larger, steady sites.
