Which functions are typically excluded from the Full Service Processor's responsibilities?

The correct choice highlights the typical division of responsibilities within the payments ecosystem. Full Service Processors generally handle core processing functions such as transaction processing, settlement, and reporting. However, they usually do not assume the risk and liability associated with credit or fraud losses. This aspect of responsibility often lies with the card issuers or financial institutions, as they manage the risks related to credit approvals, fraud detection, and chargebacks.

In contrast, marketing and customer interactions, data processing for fulfillment requests, and technical support for merchants are functions that can be either conducted by the Full Service Processor or delegated to other entities, such as the merchants themselves or third-party service providers. These capabilities are typically within the purview of business development or customer service areas, which are essential but do not involve the direct processing and risk management that Full Service Processors are responsible for.
