Artificial Intelligence (AI) smart fridges and freezers are increasingly thought of as the 'future of unattended retail'. At The Jar Healthy vending, we’re interested in how and whether they genuinely improve the consumer experience and enhance operational efficiency. Or, do conventional vending machines still perform better in many everyday settings? We’re proud to operate both models, which gives us a practical view of where each format works well.
Across more than 10 years in vending, we have learnt that AI smart fridges and freezers are not automatically superior to conventional vending machines. In some locations, they create a better consumer experience and greater product flexibility. In others, conventional vending still wins on simplicity, reliability, and consumer familiarity.
This article explores the differences between conventional vending machines and AI-powered smart fridges and freezers, drawing on our operational experience, some consumer feedback, and wider industry evidence to examine where each model delivers the strongest results.
The conventional vending machine
Conventional vending machines remain one of the most established formats in unattended retail. They are 'automated, self-service retail units that dispense mostly ambient or packaged chilled products such as snacks, drinks, and small convenience items through a mechanical coil or motor system'. They operate without on-site staff and are typically designed for simple, reliable 24/7 access. At The Jar Healthy Vending, our conventional range includes snack machines, cold drink machines, and combo units that offer both.
While the technology of conventional machines has evolved significantly in recent years, particularly through cashless payments, telemetry, and improved machine design, the core principle remains straightforward: customers select an item, pay for that item, and it is immediately dispensed to a collection section of the machine.
Operational insights
From an operational perspective, conventional vending machines perform well because they are structured, predictable, and relatively simple to run. Restocking is usually very efficient for trained operators because the machine layout is fixed and product positions are guided by slot size and a clear planogram. Although no two sites are identical, this kind of consistency helps create a repeatable, quick stocking process across venues.
Another operational advantage is serviceability. Conventional machines rely on relatively simple mechanisms, which means faults are often easier to diagnose and quicker to resolve than in more complex smart systems. This simplicity can be a major strength in locations where reliability and functionality matter most.
That said, operational simplicity can come with some trade-offs. Conventional vending may be seen as more limited in terms of what can and can’t be stocked - particularly when it comes to frozen food and larger products. While these machines are highly effective for snacks and drinks, they are less well suited to larger, irregularly shaped items such as ready meals. In practice, this means they often perform best where the demand is for quick, familiar grab-and-go products rather than full meal solutions.
What is a Planogram? A detailed visual diagram or plan that sets out the placement of products in the machine to maximise sales and make purchasing easy for the customer. At The Jar Healthy Vending, our experienced team members know the value of a simple, well-thought out planogram. When restocking, our operators bring it and stick to it – this means there's no guessing on site and our machines are always stocked with consistency in mind. |
Consumer insights
From the consumer perspective, conventional vending machines bring simplicity and familiarity. Most users already understand how they work, which makes the purchasing journey fast and intuitive: select, pay, collect. As one customer told us, “Paying for multiple products in one transaction is very convenient, also love the contactless card payment!!”
Consumer behaviour also shows that some products remain consistently popular in conventional machines. Across many venues, familiar snacks and drinks continue to sell well because they are easy to recognise, easy to choose, easy to consume on the go and well priced. Where the product, venue, and consumer need are well aligned, there is often little reason to replace conventional vending simply for the sake of newer technology. One customer told us “Great simple vending machine with an assortments of snacks! Restocked frequently as well!”
Where conventional vending works well
In our experience, conventional vending performs particularly well in environments where speed, convenience, and familiarity matter most. Logistics sites across London are a good example of this. In these settings, customers are often purchasing quickly during short breaks and are typically looking for a dependable grab-and-go option rather than a full, hot meal.
At The Jar Healthy Vending, we review sales data regularly to understand which products perform best in different venues and which machine formats are most appropriate for each location. Our ongoing analysis continues to show that, in the right environment, conventional vending remains a highly effective and commercially practical solution. As one user told us, “I thought I would never be a person to get my food from a vending machine but the selection and quality of their offering means I am sold.”
AI smart fridges and freezers
AI smart fridges and freezers are one of the most talked-about developments in the vending industry, largely because they offer a more premium, flexible and retail-like experience than conventional vending. They are 'unattended retail units that combine cooling/ freezing, and AI-enabled technologies such as computer vision and sensor systems'. In our models, customers are charged a temporary pre-authorisation amount on their card, with the final transaction value confirmed afterwards.
With recent AI advancements, these machines can be seen as modernising with the times. Customers can open the unit, browse products directly, take what they want and be charged automatically through connected payment technology.
At The Jar Healthy Vending, we have seen these systems evolve and have tested different approaches. In our experience, weight-sensing smart fridges can struggle when products have identical or near-identical weights, such as different sandwich variants from the same brand. Instead, camera-based AI systems help to reduce that issue by identifying products visually rather than relying only on weight. This can also make planogram changes more flexible, as products can be moved between shelves without requiring much recalibration.
The real advantage of AI-enabled units is not simply that they feel more modern or premium. It is that they can support a wider range of products and create a more open, retail-style experience. However, a 2024 study on autonomous retail found that, although these technologies offer clear convenience benefits, consumer adoption is still shaped by perceived risk and trust-related concerns. At The Jar Healthy Vending, we aim to address this by building trust through clear on-machine guidance and straightforward instructions that help customers understand how our AI machines work. See Image 2 for an example of our user guide.
Operational insights
From an operational perspective, one of the clearest advantages of AI smart fridges and freezers is product flexibility. Because operators are not constrained by coils, spirals, or fixed product slots, these machines can support a much broader range of items, including pots (for example, instant oat pots or noodle pots) frozen meals, ice cream, and products in different shapes and sizes (including hygeine products for example). This makes them especially attractive where the goal is to offer more than standard packaged snacks and drinks. Because of this, we are increasingly seeing organisations wanting to replace traditional forms of catering such as canteens and cafes with smart fridges and freezers.
These machines also allow greater merchandising flexibility. Products can be moved more freely, and planograms can be adapted with fewer physical restrictions than in conventional vending. In practice, that can make it easier to refresh the range, test new layouts, and respond to changing consumer demand.
However, these benefits come with additional complexity. Smart fridges and freezers rely on more advanced hardware and software, which means technical faults can be harder to diagnose and may require more specialist support. When issues arise, resolution could take longer than with conventional machines, depending on the nature of the issue.
There are also a few more things to consider when choosing the location for these machines, particularly where frozen meal solutions are offered, the machine may need to sit alongside a microwave. This introduces additional space, maintenance, and user-experience considerations.
Consumer insights
From the consumer perspective, smart fridges and freezers can feel more like a premium retail experience than a traditional vending interaction. Customers can open the unit, browse products directly, and view meals more naturally, which can make the offer feel more premium and more relevant in locations where people are looking for lunch or dinner rather than a quick snack.
The payment journey, however, is not always immediately intuitive for first-time users. Because the system places a temporary hold on the customer’s card before confirming the final charge, some explanation may be needed at first. In our experience, most users adapt quickly once they understand how the process works, but the payment model is less instantly familiar than conventional vending.
Where AI smart fridges and freezers work well
In our experience, AI smart fridges and freezers work particularly well in environments where full meals are a meaningful part of the offer and where consumers value product visibility, choice, and convenience. Busy London office settings are a strong example of this. In one of our large, high footfall office locations, our client wanted their staff to have access to hot meals throughout the day. We installed a smart freezer stocked with a selection of frozen meals that could be heated on site, and a selection of ice creams for a sweet treat. In this type of environment, the AI freezer enabled a broader, more practical food offer than a conventional vending machine would have allowed. Feedback from users at the site suggests that the smart freezer has been a huge improvement and upgrade from the previous food solution.

The Jar's view
In our view, AI smart fridges and freezers are not simply a universal upgrade on conventional vending. In the right setting, they can offer greater product flexibility, a more retail-led consumer experience, and stronger availability of meal-based food offers. But in many everyday environments, conventional vending still outperforms on familiarity, reliability, speed, and ease of operation. In our 10+ years of experience, the best choice is rarely the newest technology for its own sake. Instead, it is the format that best fits the venue, the user, and the operational reality behind it.
At The Jar Healthy Vending, we do not take a one-size-fits-all approach to product range or machine choice. We tailor products to the machine format and the venue, using sales data, operator insight, and customer behaviour to shape the offer. One of the strengths of vending is that it allows for a balanced mix of healthier and more indulgent products, depending on what users actually want from that location.
Above all, we have found that what really matters to the end consumer is customer service, machine reliability and product availability. No matter what machine our clients choose, we promise it will come with a tailor-made selection of products and an excellent service.
