Frequently asked questions
Do I have to pay the card bill before my travel voucher is paid?
Yes. The cardholder is personally responsible for paying the statement by its due date even if reimbursement is delayed. Filing your voucher promptly and using split disbursement, which sends payment straight to the card, keeps the account current.

No. The card is limited to authorized expenses connected to official travel. Personal use is misuse, and the statement you sign acknowledges the consequences, which can include losing the card and disciplinary action.
