Fans of Sardinian specialties in Munich, Germany, find what they're looking for at Il Sardo, a small restaurant and shop in the city's Schwabing district. Owner Giuliano Munzittu and his small crew - the "sardines" - rely on the slick touch interfaces of the roc.Kasse application for iPad as their transaction system. Daily balances are managed in conjunction with 4D-based roc.Center on a desktop, while further mobile functions are handled on iOS devices using roc.Mobile and roc.Kiosk.
