As wireless technologies are becoming more mature for payment systems, the public transportation companies are facing great challenges in designing their next fare collection system. They have to decide whether they want to keep their legacy systems or innovate with the implementation of new mobile technologies for their upcoming payment instrument. Therefore, they need to consider various technical and business aspects during the design process. Moreover, in such an industry, a technological consensus between the stakeholders involved is desirable to eventually reach a global market. In this paper, we propose a multi-actor multi-criteria framework to facilitate the assessment of mobile payments for the Swiss public transportation industry. To compute our proposed model, we recently conducted a first set of structured interviews with Swiss key experts to collect data.
