Providing private data is a highly controversial and widely debated topic. Not only the information about individuals but also about companies should be kept private. In order to satisfy the needs of both individuals and companies, corresponding privacy protection mechanisms have to be imple- mented. For example, systems which assist customers during their shopping process in a physical retail store require customer related information, such as the shopping list, allergy or bank account information as well as data from the retailer, like the product range and prices. In this paper, we introduce a concept for decoupling both information sources implemented in a shopping scenario, which amongst others allows Mobile Payment without the transmission of private data. The implemented prototype has been presented at a large fair to potential users in order to receive valuable feedback.
