To contribute to a further integration of payments in the European digital market, the has facilitated in May 2018 the creation of an ad-hoc multi-stakeholder group on mobile initiated credit transfers, including Instant Credit transfers ( Inst) (MSG MSCT). This group has now finished the development of a final draft document on “MSCT Interoperability Implementation Guidelines” (MSCT IIGs - MSG MSCT 026-19v0.9).

These guidelines aim through the description of MSCT use cases to provide an insight into the main issues related to the initiation of (instant) credit transfers in different mobile payment contexts such as person-to-person, consumer-to-business (retail payments including both in-store and m-commerce payments) and business-to-business payments. Next to the MSCT transaction aspects such as payer identification/authentication, transaction authentication, risk management and payer/beneficiary acknowledgements and notification messages it focuses on the technology and security used in the customer-to-ASPSP space, since the Inst and transactions as such have already been specified in the respective rulebooks). It furthermore specifies various security guidelines for MSCTs (e.g. MSCT app, CDUVM , etc.). Finally, the document discusses the main interoperability issues and barriers detected for MSCTs.

By developing these interoperability implementation guidelines, the multi-stakeholder group aimed to contribute to a competitive MSCT market, by providing the different stakeholders with an insight into the different service, technical and security aspects involved. The document could serve as a reference basis for making certain implementation choices.

In order to help developing a successful MSCT ecosystem that provides value for all, it is very important to gather industry opinion and feedback regarding these guidelines. The multi-stakeholder group values your opinion and welcomes any feedback and comments that you can provide regarding the document, using the dedicated questionnaire (MSG MSCT 032-19v1.0). Feedback should be sent to by 23 August 2019.
