The goal of the Swiss Payment Monitor is to comprehensively illuminate the Swiss payment landscape from different perspectives. By combining different research methods, the study offers an integrated view of the payments market and enables new developments to be recorded and relevant drivers to be identified over time through regular data collection. The study includes an online survey with questions on payment behaviour and a payment diary filled out by the respondents over three days. Additionally, publicly available data material on electronic payment transactions are used to embed and interpret the findings.
