What type of alerts might be set during fraud monitoring?

When it comes to fraud monitoring, the identification of suspicious activities is critical. Alerts for excessive credits, chargebacks, or duplicate amounts are directly relevant to detecting potential fraudulent behavior in transactions. These alerts help businesses and financial institutions analyze patterns that could indicate fraud. For instance, an excessive number of chargebacks might suggest that a user is disputing transactions frequently, potentially indicating fraud either on the part of the merchant or the consumer. Similarly, duplicate amounts could represent a risky transaction that warrants further investigation to prevent financial loss.

On the other hand, promotional alerts for sales, notifications for customer feedback, and updates on marketing campaigns are not geared toward fraud detection. Instead, they serve marketing and customer service purposes without offering insights into potentially fraudulent activities. Thus, they are not relevant in the context of fraud monitoring, making alerts for excessive credits, chargebacks, or duplicate amounts the appropriate option for this question.
