Also, the third-party service provider to which the payment and settlement activities have been outsourced by the PSOs have to be able to isolate and clearly identify the PSO's customer information, documents, records, and assets to protect their confidentiality. “Where the service provider acts as an outsourcing agent for multiple PSOs, there should be strong safeguards (including encryption of customer data) to avoid co-mingling of information, documents, records, and assets of different PSOs,” the RBI said.
