Admin, Employee, and Budget Owner users have the ability to assign Permitted Spending Categories for an existing Rho Card. This can be modified from the Card Limit field on the Card Settings page for the card.
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.
