This report presents the results of our self-initiated audit of Voyager Card Transactions – Chino, CA, Post Office. The Chino, CA, Post Office is in the California 4 District of the WestPac Area. This audit was designed to provide U.S. Postal Service management with timely information on potential financial control risks at Postal Service locations.
Every Postal Service-owned vehicle is assigned a Voyager credit card to pay for its commercially purchased fuel, oil, and routine maintenance. U.S. Bank is responsible for operating the program and Voyager provides a weekly electronic transaction detail file of all Voyager card transactions to the Postal Service’s Fuel Asset Management System (FAMS) eFleet application. Site managers are responsible for monitoring Voyager card transactions in the FAMS eFleet application. FAMS provides a monthly Reconciliation Exception Report, capturing transactions categorized as “high-risk,” which may be the result of fraudulent activity. Each month, the Postal Service site manager is responsible for ensuring that their driver receipts are reconciled in FAMS. The review is critical since the Postal Service automatically pays U.S. Bank weekly for all Voyager card charges.
Transactions marked as “high-risk” in FAMS could be due to gallons of fuel purchased exceeding the allowed maximum amount for the vehicle, unleaded super and plus fuel purchase, and potential sharing of personal identification numbers (PIN). These indicate questionable transactions which signify a higher risk of fraud.
