This paper describes an exploratory study on the design space for mobile payments. The study aims at identifying how some features of potential systems may affect the end-user experience and the overall values associated with it. This work takes an interaction design perspective and is not particularly focused on usability or task efficiency issues. Instead, we provide a set of concepts towards the generation of a framework about the Human values involved in mobile payments. The proposed framework and the results from users’ interviews provide an added-value for anyone designing mobile payment systems. The resources presented should facilitate the reasoning about the major sensitivities involved in mobile payments as well as initial reflections of their implications.
