Rudd-Melikian company, stated that Kwik Kafe machines purveyed 250,000 cups of coffee on a daily basis. Additional companies that manufactured coffee vending machines in 1947 in the United States include the Manning & Lewis company, Knapway Devices and the Bert Mills Corporation. Some machines in 1947 used a liquid coffee concentrate that was mixed with boiling water, and one such machine charged a nickel for a cup of coffee and dispensed a wooden spoon to mix the cream and sugar. By the year 1955, over 60,000 coffee vending machines existed in the United States. Concept machines Touch screen coffee machines, such as those introduced by Bella, Bravilor Bonamat and La Marquise are becoming increasingly popular as they allow closer engagement with customers. In 2009, Douwe Egberts introduced a conceptual coffee vending machine named BeMoved, which has touch screens with drag and drop features to select ingredients and interactive features such as the ability to access news, weather information and stock prices as the coffee is prepared. The BeMoved machine also has a motion-sensitive video camera that can take an image of the user and remember the user's coffee preferences via personal profile settings, as well as an interactive video game named Shoot-Em-Up, which involves jumping in front of the machine while the camera and software coordinate the jumping with the video game play.
