Establish a basis for new capabilities
If we look to the future, it is likely that touchscreens and modern electronics will be used to enhance merchandising opportunities in vending. When this happens, there will be greater opportunities to conform with government regulations around calorie and nutritional information, advertise products, offer promotions, and administer and promote loyalty programs.
The challenge in making these programs work is that the vending machine will need to know which products are in each spiral. Companies using advanced software and/or remote monitoring solutions can do this today.
In closing, make sure you have a strategy for tracking item level sales, and approach merchandising as a way to increase your profits.
