1. Classification by product

Vending machines are often grouped by the goods they sell:

• Snack vending machines: snacks, candy, chips and similar packaged goods

• Beverage vending machines: sodas, water, juice, coffee and other drinks

• Fresh food vending machines: sandwiches, salads and other perishable items

• Healthy food vending machines: fruit, nuts and low-calorie options

• Specialty vending machines: electronics, cosmetics, personal care items and more

• Hybrid vending machines: both food and non-food items, such as snacks combined with electronics

2. Classification by size and installation

• Floor-standing machines: large capacity for high-traffic locations

• Tabletop machines: compact units that sit on a counter or table

• Wall-mounted machines: save floor space and hang on a wall

3. Classification by technology

• Basic vending machines: buttons or keypad, bill and coin payment

• Interactive and smart vending machines: touchscreens, cashless payment, advertising display and remote monitoring

• Customized vending machines: designed for a specific brand or purpose, such as a branded machine for a company or university campus

4. Snack and drink vending machines

The classic type. Products sit on spiral or belt trays and drop to a delivery outlet. Modern versions use touchscreens, such as a 22-inch or 55-inch display, that show products and play picture and video advertisements. A large 55-inch touchscreen machine with a spiral goods tray works as both a sales point and a digital advertising board.

Best for: offices, schools, hospitals, malls, stations and any place with steady foot traffic.

5. Coffee vending machines

Coffee vending machines range from instant coffee machines, which mix powder with hot water, to bean-to-cup machines that grind whole beans for each cup. Table-top models fit meeting rooms and small shops, while floor-standing machines handle higher volumes. Cashless payment support is common.

Best for: offices, hotels, restaurants, retail spaces and waiting areas. See the MINNO coffee vending machine range, including the table-top coffee vending machine.

6. Smart fridge vending machines

A smart fridge vending machine looks like a fridge, but uses technology such as weight sensors to detect which products the customer takes. Single-door and double-door versions exist, and a card reader lets customers open the door and pay automatically. Existing fridges can also be converted into vending machines with a conversion kit.

Best for: fresh food, drinks and goods sold by piece in apartment buildings, offices, gyms and hotels.

7. Locker vending machines

A locker vending machine stores products in individual lockable compartments. When the customer pays, the matching compartment opens. Compartment sizes can be customized, and cooling versions keep goods cold. This type suits products that do not fit spiral trays, such as large, valuable or oddly shaped items.

Best for: electronics, accessories, chilled goods, click-and-collect orders and shared storage points.

8. PPE vending machines

A PPE vending machine dispenses personal protective equipment such as gloves, safety glasses or earplugs. It uses spiral goods trays and lockers and can connect to an employee identification system, so companies can control and track who takes which item.

Best for: factories, warehouses, construction sites and workshops.

9. Cup noodle vending machines

A cup noodle vending machine sells instant noodles and supplies hot water after purchase, so customers can prepare their meal at the machine. A 21.5-inch touchscreen gives a modern interface.

Best for: campuses, factories, transport hubs and night-time locations.

10. Draft beer vending machines

A self-service beer machine with taps offers customers cold draft beer. A typical configuration provides four beer options. Alcohol sales are subject to local laws, so operators should confirm age verification and licensing requirements before installation.

Best for: licensed venues, entertainment spaces and events, where regulations allow.

11. Small and wall-mounted vending machines

Compact machines save space and lower the entry cost.

• Small tabletop vending machine: a keypad and 5-inch LED screen, designed to sit on a table

• Keyboard smart vending machine: keyboard operation with a 5-inch LCD screen for snacks and drinks

• Small wall-mounted vending machine: a 21.5-inch touchscreen without a cooling system, hung on the wall

Best for: small offices, reception desks, shops and places with limited floor space.

12. Where each type works best

13. How to choose

Ask these questions before you decide:

1. What will you sell? Product size, shape and temperature needs decide the tray and cooling type.

2. Where will it be installed? Check space, power and network access.

3. How will customers pay? Choose cash, card, e-wallet or ID card support.

4. Do you need advertising or branding? A large touchscreen can play your promotions.

5. Do you need remote management? Real-time stock and sales data save service trips.

6. Do you need customization? A custom wrap or special configuration can help your machine stand out.
