Which action is considered misuse of the US Bank Card?

Making personal purchases with the US Bank Card constitutes misuse of the card because the card is intended solely for official government business and expenses related to the performance of duties. When cardholders use the card for personal purchases, it violates the principles of proper use and accountability associated with government funds. The funds available through the card are meant to facilitate official expenses such as travel or necessary supplies for agency operations, rather than personal expenditures that do not pertain to government business.

In contrast, using the card for official travel, requesting reimbursements for business expenses, and purchasing supplies for the agency are all actions aligned with the card's intended purpose. These activities follow established guidelines, promote accountability, and ensure that government resources are utilized appropriately for work-related tasks. This underscores the importance of adhering to policies that govern the use of government-issued cards to prevent misuse.
