Enabling Merchant Category Controls (MCC) on a card restricts card payments to merchants only within selected categories. The available merchant categories are:
Fuel
Airlines
Hotels and Lodging
Government Services
Repairs
Travel and Transport
Telecommunication Services
An administrator can set up merchant category controls at the time of card issuance. These can be modified later if need be. Navigate to Cards on the admin dashboard and select the card that needs to have category controls. By default, all new cards will not have any category controls enabled.
