What is a common guideline for travel card usage?

Travel cards are specifically designed to facilitate official travel for employees on behalf of an organization. The correct answer highlights that travel cards should be utilized for expenses related to airfare, hotel accommodations, and car rentals incurred during official business travel. This guideline ensures that expenses are appropriately accounted for and that the funds are used in accordance with the organization's policies regarding travel.

Using the travel card for these categories of expenses is crucial as it aligns with proper financial management and reporting practices. It allows for efficient tracking of official travel expenditures, helping organizations maintain financial accountability and ensuring that employees are not personally burdened by costs related to their official duties.

The emphasis on using the travel card strictly for official travel-related expenses ensures that organizational resources are allocated appropriately and that the integrity of travel funding is maintained.
