Full title and description

ISO/TS 12812-4:2017 — Core banking — Mobile financial services — Part 4: Mobile payments-to-persons. This technical specification provides requirements, recommendations and use cases to support interoperable mobile person-to-person (P2P) payment services as part of mobile financial services programs.

Abstract

ISO/TS 12812-4:2017 defines program-level requirements and recommended mechanisms for operating interoperable mobile payments-to-persons. It presents a generic interoperability model, a three-layer high-level architecture, descriptions of payment instruments and detailed transaction flows for bank-centric, non‑bank‑centric and card‑centric implementations. The specification also addresses remittances, financial‑inclusion considerations and selected legal aspects, and includes use cases with corresponding data flows.

Scope

This TS specifies the requirements that a mobile payments‑to‑persons program must satisfy and gives recommendations for technical and organizational mechanisms to achieve interoperability between participating payment service providers. It covers architecture layers, supported payment instruments, transaction processing flows (including bank‑centric, non‑bank‑centric and card‑centric models), remittance scenarios, use cases and annexed guidance on financial inclusion and legal aspects. The focus is operational and interoperability‑oriented rather than on low‑level protocol specifications.

Key topics and requirements

• Program requirements and governance for mobile P2P payment services (consumer protection, transparency, auditability).
• Interoperability principles and a generic interoperability model for mobile payments‑to‑persons.
• Three‑layer high‑level architecture (service, processing and transport/communication layers) and mapping of payment instruments.
• Detailed transaction and data flows for bank‑centric, non‑bank‑centric and card‑centric implementations.
• Recommendations for technical implementation, including device/application considerations, logging, authentication and authorization practices.
• Guidance on mobile remittances and support for financial inclusion of unbanked/underbanked users.
• Discussion of legal and policy aspects relevant to mobile P2P deployments (annex material).

Typical use and users

Primary users include banks, mobile network operators, fintech and payment service providers, system integrators, solution architects, regulators and standards implementers planning or operating interoperable mobile P2P payment programs. The TS is used to shape program requirements, interoperability arrangements, and high‑level technical designs rather than as a protocol specification.

Related standards

ISO/TS 12812‑4:2017 is part of the ISO 12812 series on core banking — mobile financial services (see Parts 1–5). Related parts include ISO 12812‑1 (general framework), ISO/TS 12812‑2 (security and data protection) and ISO/TS 12812‑5 (mobile payments to businesses). Implementers often consider this series alongside payments and messaging standards (for example ISO 20022) when designing interoperable mobile payment solutions.

FAQ

Q: What is this standard?

A: ISO/TS 12812‑4:2017 is a Technical Specification that defines requirements, recommendations and use cases to enable interoperable mobile payments‑to‑persons (P2P) within the broader ISO 12812 mobile financial services framework.

Q: What does it cover?

A: It covers program governance and mandatory requirements, interoperability principles, a three‑layer architecture, supported payment instruments, detailed transaction flows for different implementation models (bank‑centric, non‑bank‑centric, card‑centric), remittance guidance, and annexes on financial inclusion and legal aspects.

Q: Who typically uses it?

A: Banks, mobile operators, fintechs, payment service providers, system architects, integrators and regulators use the TS to design interoperable mobile P2P services and to define program and interoperability requirements.
