Paper Abstract:	Launched in Congo in 2012 by mobile phone operators, Mobile Money is a digital financial service that offers the possibility of opening an account for free and carrying out financial transactions for free. The flexibility and ease of access to this service has therefore encouraged its integration into all social strata of the population. Subscribers can then carry out several types of operations: pay bills, transfer money, receive money, deposit money, etc. However, the fact that financial transactions are still very expensive and are currently only carried out between subscribers of the same mobile operator is a real limitation that must be overcome. In addition to this high cost limitation and the lack of a gateway between operators, which we want to remedy, the old hierarchical USSD (Unstructured Supplementary Service Data) or SIM (Subscriber Identity Module) toolkit menu interfaces discourage many users. A single cash transaction can require seven to eight menu screens and the entry of two to three sequences of numbers. Mistakes are too easy. Smartphone interfaces not only have the potential to simplify basic transactions, but they can also solve many other obstacles. They can display content in a richer and clearer way than simple text. In this article, we propose an innovative solution, called "One Cash", which provides a concrete and practical solution to these major concerns by integrating the APIs of mobile and/or financial operators and exploiting the richness and flexibility of smartphone interfaces to simplify usage. In particular, content is presented in a richer and clearer way than simple text, the number of manipulation steps has been reduced with the proposed solution, thus reducing the user's cognitive load, customers quickly sign up for new services, and can even self-register without having to fill out costly paper forms or visit a branch or kiosk, etc. In this article, we highlight the interest of a diversified offer of m-payment services including a simplified solution offered by the operator alone, and more elaborate services, in particular by associating technological and financial partners such as banks. The proposed architecture is easily adaptable to meet future extensions and improvements of the system.
