Are you looking for a policy with the rules related to employee use of company credit cards, or on protecting customer information when they purchase products with a credit card?

We limit use to business travel expenses:

The company credit card is intended for valid business travel expenses only (e.g., air travel, car rental, hotel charges, meals). The employee is responsible for paying all company credit card monthly statements according to the stated terms. To receive reimbursement of business travel expenses, the employee must submit a complete business expense report (along with supporting documentation) for reimbursement. The company credit card is a personal liability, therefore failure to comply with its policy may negatively impact the employee's personal credit history. Card privileges will be suspended if the employee does not pay the monthly bill on time.  The company credit card will be cancelled upon termination of employment for any reason.

 Hope this helps!

Our credit cards are for travel only also, so I don't know if this is what you need...

Allowable Expenses

Air, rail, and other travel - Used passenger coupons or ticket stubs must be attached to expense report forms. Charges for changes in flights due to a personal decision of the employee are the responsibility of the employee.

Hotel - Proper receipts must accompany the expense report. Charges for reservations guaranteed but not used will be reimbursed only if the failure to use the reservation was due to reasons beyond the employee’s control.

Car rental, parking fees - Receipts must be attached to the expense report.  Additional insurance coverage that is offered by the rental agency should be declined.

Meals - Employees will be reimbursed for a maximum of three meals per day. Meals provided for business associates must be fully explained. Meal costs in excess of $10.00 and not substantiated by receipts may be disallowed.

Disallowed Expenses

Personal expenses, such as evening beverages, cocktails, movies, newspapers, magazines, haircuts, laundry, dry cleaning, etc. are not allowed.
