This paper builds on a fairly comprehensive review of the scientific literature, relative to the recent development of mobile payment systems. It presents the main current solutions and some implementations. However, many issues remain open, including the security of personal data, which raises ethical concerns related to privacy, among other concerns. The article shows how, in the Covid-19 era, ethics are an asset for improving digital trust in mobile payment systems that have become essential tools in the lives of citizens.}}
