Types of Smart Vending Machines

Pop-out Vending Machines: Mechanically Precise Control
In the most common pop-out vending machines, such as those that sell beverages, after you select a product, a spring track, electric push rod, or rotating device inside the machine will "push" the selected item into the retrieval slot. During this process, users cannot directly touch other items on the product shelf. Therefore, such vending machines do not need to "determine what you took" because they control the entire retrieval process. Users can only obtain the item that the machine dispenses according to its programmed operation, completely eliminating the possibility of taking the wrong item or stealing. This is the biggest advantage of "closed vending machines": simple, safe, and reliable.

Free-Access Vending Cabinets: You Take, I Watch
When you face a smart vending cabinet that allows you to freely open the door and select products, the technical challenge becomes much more complex. It needs to automatically determine what you took, how many items you took, and even whether you put any items back after you open the door, take products, and close the door.
