Admin, Employee, and Budget Owner default user groups as well as any custom user groups that have the "Manage Team Card Permissions" permission toggled "On" have the ability to assign Permitted Spending Categories for an existing Rho Card. This can be done by clicking the Actions button and selecting Card Settings from the drop-down list.
Selecting Permitted Spending Categories restrict Rho Card transactions to only the categories selected from the drop-down list. For example, you can select Airlines, Air Carriers and Airports, Flying Fields, if you want the card to only be used for air travel expenses.
