The electronic market has rapidly grown in the last few years. However, despite this success, consumers still enjoy visiting a store with real products. Therefore various common technologies have been installed in supermarkets to support the customer's shopping process and experience. In this paper, we introduce the IRL SmartCart - an instrumented shopping cart that acts as a user interface to support the shopping process. We show how RFID technology enables recognizing products that are put in the cart's basket. We are also able to determine the cart's position in an instrumented shopping environment. User input and visual output are possible by means of a touch screen, which is fitted in the IRL SmartCart's handle to support different tasks involved in the shopping process. We present and discuss different location- and context-based services that run on the cart interface system, e.g. a personalized shopping list sorted corresponding to the products in the user's vicinity or a navigation service to different products that the customer is searching for.
