Core banking — Mobile financial services — Part 4: Mobile payments-to-persons
ISO/TS 12812-4:2017 provides comprehensive requirements and recommendations, as well as specific use cases for implementation of interoperable mobile payments-to-persons. The emphasis is placed on the principles governing the operational functioning of mobile payments-to-persons systems and processes, as well as the presentation of the underlying technical, organizational, business, legal and policy issues, leveraging legacy infrastructures of existing payment instruments (see ISO 12812‑1:2017, Annex C). ISO/TS 12812-4:2017 includes the following items: a) requirements applicable to mobile payments-to-persons; b) recommendations regarding mechanisms involved in the operation of interoperable mobile payments-to-persons; c) a description of the different use cases for mobile payments-to-persons; d) a generic interoperability model for the provision of different mobile payments-to-persons; e) recommendations for the technical implementation of the generic architectures for the mobile payments-to-persons program; f) recommendations for mobile remittances; g) use cases with the corresponding transaction flows; h) discussion of the financial inclusion of unbanked and underbanked persons (Annex A); i) some legal aspects to consider for mobile payments-to-persons (Annex B). ISO/TS 12812-4:2017 is structured as follows: - Clause 6 sets forth the requirements that a mobile payments-to-persons program must comply with. - Clauses 7, 8 and 9 provide the different levels of implementation for the interoperability of mobile payments-to-persons. - Clause 7 describes the interoperability principles for mobiles payments-to-persons. - Clause 8 describes: a three-layer high-level architecture for mobile payments-to-persons programs; payments instruments sustained by these programs; processing details for a series of significant use cases of mobile payments-to-persons using these payment instruments. - Clause 9 provides a step-by-step data flow description for different mobile payments-to-persons implementations: bank-centric, non-bank centric and card-centric. They can be mapped into the processing use cases of Clause 8, where abstraction is made in the nature of the payment service providers.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commiss
