Cafe is a Food and Beverage Service. A good cafe in terms of service quality includes Cleaning Service, Waiters, Service in ordering menus (Point of Sales), and others. The case study in this study took the Malang Native Cafe as the object of research which in this case did not yet have technology related to the POS system. In this case, the researcher makes a Point of Sales interface design display in the form of an Android Application so that the Natives of Malang have an overview of the initial Point of Sales design display. The prototype method is used in this study because it has the advantage that it can create a system in a very short time but still pay attention to the needs of the user itself. The results of this study were obtained through several phases, namely looking for related literature studies, analyzing the needs of the Hardware & Software used, then proceeding to the Communication phase which finally resulted in Goals and identification of the features needed, then Quick Plan & Quick Design, Prototype Construction, namely making Low-Fi and Hi-Fi Prototype, and continued with Delivery & Feedback to get feedback through the Usability Testing Maze which was then shared with the link to related testers/respondents as many as 66 data samples for later testing using the SUS technique which got results with an average score of 85.03 " Acceptable" or "Excellent" with "Grade B" and the SEQ technique with an average score of 6.33 which is rounded up to 6 so that it meets the "Easy" criteria to use
