From Traditional Vending to a “Open, Take, and Go” Shopping Experience

For this unmanned retail project in France, the customer needed a solution that could sell more than just drinks and snacks. The machine also had to accommodate yogurt, sandwiches, bread, desserts, ready meals, and other food products in different sizes and packaging formats.

Traditional spiral vending machines rely on fixed product channels. This can limit product flexibility, especially when selling soft, fragile, or irregularly shaped food packages that are not suitable for drop-style dispensing.

The customer therefore selected the WEIMI Smart Gravity-Sensing Vending Cabinet, combining open-shelf merchandising, weight detection, and automated checkout to create a shopping experience closer to a small convenience store.

At the French installation site, the machine is already being used to sell bottled drinks, canned beverages, yogurt, pastries, bread, sandwiches, and different types of packaged food, allowing one machine to support a much broader product mix.

The Main Challenge: Selling Different Types of Food in One Machine

For a self-service food retail project like this, the customer needed more than simply a machine that could dispense products.

The key challenge was how to sell products with different sizes, weights, and packaging formats through one automated retail system.

Bottled drinks are relatively standardized, but sandwiches, bread, pastries, desserts, and meal boxes can vary significantly in size. If all of these products were placed in traditional fixed vending channels, changing the product mix later would become more difficult.

At the same time, the customer wanted the purchasing process to remain simple. Shoppers should not need to select and confirm every individual item on the touchscreen before taking it.

This was one of the main reasons the customer chose a gravity-sensing vending cabinet.

WEIMI Gravity-Sensing Vending Cabinet: Shelf-Style Display for a Wider Product Range

Unlike a traditional vending machine, the gravity-sensing cabinet uses a merchandising layout closer to conventional retail shelving.

Each product area is equipped with a weight-detection system. Product information and individual item weight are configured in the management system in advance.

When a customer opens the door and removes a product, the system detects the change in shelf weight and calculates how many items have been taken.

This means operators do not need to configure a separate mechanical dispensing process for every product.

Drinks can be placed on one shelf, yogurt and desserts on another, while sandwiches, bread, and packaged meals can be arranged according to their actual sizes.

For food retail projects where SKUs change frequently, this provides much greater merchandising flexibility.

Localized French Interface for Easier Customer Operation

For the French market, the machine was configured with a localized French-language purchasing interface.

The touchscreen guides customers through a simple purchase process, including instructions such as:

Ouvrir la porte — Open the door
Prendre le produit — Take the product
Fermer la porte — Close the door

The entire shopping process is designed to be as straightforward as possible.

After completing payment authorization or identification, the customer opens the cabinet, takes the products they want, and closes the door. The system then calculates the order based on the detected weight changes.

Compared with the traditional vending process of “select product — enter number — wait for dispensing,” this workflow feels much more natural.

It also reduces the learning curve for first-time users.

Customers Can Take Multiple Products in a Single Purchase

Another advantage of the gravity-sensing system is that customers do not need to make a separate transaction for every item.

For example, a shopper can take:

a bottled drink, a yogurt, and a sandwich in one visit.

The system detects the weight changes across the relevant shelves and combines the selected products into the same order.

For customers purchasing breakfast, lunch, or several items at once, this can be more convenient than traditional one-item-at-a-time vending.

For the French customer, this also helps transform the machine from a conventional vending unit into a small self-service convenience retail point.

A Wider Product Range in a Single Vending Cabinet

The actual product assortment in this French deployment demonstrates the flexibility of the machine.

Products include bottled water, soft drinks, canned beverages, yogurt, pastries, sandwiches, bread, and different types of packaged foods.

The transparent glass doors allow customers to see the real products before purchasing, while internal LED lighting improves product visibility and presentation.

This is particularly useful for food retail.

Customers can directly view product packaging, size, and remaining stock rather than relying entirely on digital product images displayed on a screen.

For operators selling fresh food, bakery products, and ready-to-eat meals, this visual merchandising approach provides an experience closer to shopping from a physical retail shelf.

Gravity Sensing Reduces the Limitations of Mechanical Dispensing

When sandwiches, desserts, or meal boxes are sold through a traditional spiral vending machine, operators usually need to carefully match product dimensions with the channel size.

Soft packaging or irregularly shaped products may also create a higher risk of dispensing problems.

A gravity-sensing vending cabinet does not need to push or drop products through a mechanical vending channel.

Instead, products remain on the shelf until the customer removes them directly.

This makes the system particularly suitable for:

beverages, dairy products, sandwiches, bread, pastries, salads, packaged meals, and other food products in different shapes and sizes.

For operators that frequently update their product assortment, restocking and product replacement can therefore become much more flexible.

Remote Management Makes Unattended Retail Easier to Operate

The value of an unmanned retail system is not limited to the customer-facing shopping experience.

For operators, understanding inventory levels and sales performance is equally important.

Through the remote management system, the operator can review product sales and inventory changes and arrange replenishment according to actual demand.

For example, if beverages and sandwiches are selling quickly, more stock can be allocated to those categories. Slower-moving products can gradually receive less shelf space.

This allows the operator to optimize the product mix based on real sales data rather than relying entirely on manual estimates.

As more machines are deployed, multiple locations can also be managed through a centralized backend, reducing the need for frequent on-site inspections.

One Gravity-Sensing Cabinet Can Work Like a Small Unmanned Convenience Store

This French project clearly demonstrates the difference between a gravity-sensing cabinet and a conventional vending machine.

The objective is not simply to automate product dispensing.

Instead, the system brings part of the convenience-store shopping process into a compact automated retail format:

customers see the actual products, open the door, freely take multiple items, close the door, and complete the purchase automatically.

For operators that want to offer a broader range of food without opening a fully staffed retail store, this model creates a useful balance between compact footprint, product variety, and unattended operation.

A More Flexible Unmanned Food Retail Solution for the French Market

Through this customer project in France, the WEIMI Smart Gravity-Sensing Vending Cabinet has demonstrated its ability to support self-service sales across a diverse range of food products.

From beverages and yogurt to bread, sandwiches, desserts, and packaged meals, products of different sizes can be displayed flexibly within the same machine.

By combining smart weight detection, a localized French interface, transparent product display, automated checkout, and remote management, operators can build a simpler and more flexible unattended food retail point.

For convenience stores, offices, factories, schools, apartments, hotels, and other locations that want to provide 24/7 food access, the gravity-sensing vending cabinet offers a more adaptable alternative to traditional fixed-channel vending machines.
