According to the Basel Committee principles, which actions would make a customer identification program at a bank more robust?

While this understanding can offer insights into customer preferences and satisfaction, it does not directly enhance the identification or verification process. Knowing a customer's choice of bank does not provide specific information about their identity or the legitimacy of their financial activities.

This is crucial as it allows the bank to assess the risk profile of the business and ensure that the account is being used for legitimate purposes. Understanding the nature of a business helps in tailoring monitoring and controls to prevent potential money laundering or fraud.

Restricting a new customer's online activities does not contribute to the robustness of the identification program. In fact, it may hinder the customer's ability to conduct necessary transactions and does not address the importance of verifying their identity or understanding their banking needs.

This action is essential as it ensures that the bank has accurate information regarding the customer's identity, reducing the risk of fraud and enhancing compliance with regulatory requirements. Using reputable sources for verification provides an additional layer of security in the identification process.
