(9)Payment card schemes and processing entities should be allowed to use shared services provided that this usage does not result in sharing sensitive information between them and that the conditions for sharing the services, including the financial conditions under which those services are offered, are duly documented in a single document. That document should be made available to competent authorities upon their request to enable them to ensure the application of independence requirements. Specific conditions for the sharing of the information management system should be introduced. Sharing of sensitive information between payment card schemes and processing entities which may give either the payment scheme or the processing entity a competitive advantage should however be prohibited.
