<p>Goods are sold in reusable packaging from vending machines where the customer can pay for them using coins, paper money or cards. The machines can also print stickers. The rear side of the vending machine has a refillable container for the goods which is provided with a measuring system that enables a stock manager to be alerted via e.g. the internet that the container is nearly empty, so that the container is automatically restocked.</p> |
