Coin operated LUNA ice cream machines
A token module is an option when a self serve machine is your choice, With a token/coin device your machine is better guarded against the unauthorized consumption of ice cream. One can only obtain an ice cream from the machine after puting a token into the side mounted device. The side-mounted token module, can be combined with a sirup device in the same side module.
The LUNA self service ice cream machines are fitted with advanced sensors to detect used cones and will refrain from dispensing any product into a used cone. However the absolute fail proof method for self service soft serve ice cream and milk shake machines is a token device. The down side of this fail proof method is the fact that you will have to manage two currencies in your till.
