According to the ACAMS CAMS Certification Study Guide, 6th Edition, one of the four pillars of an effective anti-money laundering compliance program is the training of appropriate employees on their responsibilities and the institution's policies and procedures. Training is essential to ensure that employees are aware of the risks of money laundering and terrorist financing, the applicable laws and regulations, the red flags and indicators of suspicious activity, and the reporting and record-keeping requirements. Without proper training, employees may not be able to perform their duties effectively and efficiently, and may expose the institution to legal, regulatory, reputational, and operational risks.

According to the Financial Action Task Force (FATF) 40 Recommendations, financial institutions should obtain senior management approval before establishing new correspondent banking relationships1. This is to ensure that the financial institution has assessed the money laundering and terrorist financing risks associated with the respondent institution and has applied appropriate due diligence measures. The FATF also requires financial institutions to gather sufficient information about the respondent institution, its business activities, its reputation, its supervision, and its anti-money laundering and counter-terrorist financing policies and procedures1. Additionally, the FATF recommends that financial institutions document the respective responsibilities of each institution and prevent the use of their accounts by shell banks1.

One of the key components of an effective anti-money laundering (AML) program is customer due diligence (CDD), which involves verifying the identity of the customer, understanding the nature and purpose of the customer's relationship with the financial institution (FI), and assessing the risk of money laundering or terrorist financing that the customer poses. CDD is essential for preventing and detecting the misuse of the FI's services by criminals, and for complying with the relevant laws and regulations.
However, CDD can be challenging for FIs that offer online services to customers, as there is a greater difficulty in matching the customer with the provided identification documentation. Unlike face-to-face interactions, online services rely on electronic or remote methods of identification and verification, such as scanned copies of documents, biometric data, digital signatures, or third-party verification services. These methods may not be as reliable or secure as physical verification, and may expose the FI to the risk of identity fraud, document forgery, or impersonation. Moreover, online services may attract customers from different jurisdictions, which may have different standards and requirements for identification and verification, and may pose different levels of risk.
Therefore, FIs that offer online services to customers should implement enhanced due diligence (EDD) measures to mitigate the risk of money laundering, such as obtaining additional information or documentation from the customer, applying more stringent verification procedures, conducting more frequent and intensive monitoring of the customer's transactions and behavior, and restricting or limiting the types or amounts of transactions that the customer can perform online.
