The RVMs are transparent from a VOP scheme rulebook perspective but technically, they need to be registered in the EDS to act on behalf of the scheme participants. Furthermore, RVMs play a key role to ensure interoperability, as a large part of VOP scheme participant PSPs are expected to make use of one or more RVMs for issuing VOP requests and/or receiving VOP responses.
To ensure a secure and optimised access to the EDS through EDS APIs, the RVMs need to be registered and onboarded in the EDS and to this end, the EPC requires these RVMs to adhere to technical and security terms set forward by the EDS provider.
Consequently, the RVMs must be qualified by the EPC and comply with the requirements set out by the EPC. More information about the qualification process and the EPC RVM Agreement can be found here.
The EPC will publish on its website the list of VOP RVMs and the status of their qualification process (ongoing or completed).
