Using shopping data to design sustainable consumer apps

The Internet of Things is greatly changing the buying and consuming behavior. Future scenarios of smart shopping, smart kitchen and smart cooking become increasingly real and integrated. In this context we see current attempts of creating digital receipts in the food retailing industry. Respectively to these attempts, this paper shows that consumers expect a number of added values from the digital receipt, e.g. a higher transparency for a better self-reflection, therefore a more sustainable food consumption and more information about the bought products. We conducted qualitative interviews to find out how people use receipts and what added values they can imagine in terms of a digital receipt to improve their consumption behavior and to reduce food waste. Since all bought products will be registered digitally, it becomes possible to use the shopping data for sustainable consumer apps.
