What role does a Cardholder MSP play?

The role of a Cardholder Merchant Service Provider (MSP) primarily involves orchestrating customer service for cardholders. This includes handling inquiries, providing support for transaction-related issues, and assisting cardholders with understanding their statements and charges. Customer service is a critical component of the overall payment experience, as it directly impacts cardholders' satisfaction and trust in the card system.

While the other options describe important functions within the payment ecosystem, they do not align with the specific duties of a Cardholder MSP. For example, issuing credit cards typically falls under the responsibilities of financial institutions or banks, while investigating card fraud is usually managed by fraud prevention teams or risk management departments within financial organizations. Managing cardholder profiles might involve data management systems rather than the dedicated service focus of an MSP. Thus, orchestrating cardholder customer service is the most fitting and accurate description of the Cardholder MSP's role.
