A bank sells reloadable open-loop prepaid cards to both customers and non-customers.

According to the CAMS Study Guide, page 191, “Reloadable open-loop prepaid cards are a high-risk product for money laundering because they can be used to store and move large amounts of funds anonymously. They can also be used to access cash at ATMs or through cash-back transactions at merchants.” Therefore, option B is a red flag that may indicate money laundering, as a non-bank customer who regularly loads large amounts of cash onto several prepaid cards may be trying to avoid identification, verification, or transaction reporting requirements.
