How do I activate my card? 

Directions to activate your physical cards. Virtual Cards are active upon creation.

Log into your account, go to Cards in the main menu, click the ellipsis next to your card status, and click “Activate”. Enter your new card information here. Cards can only be activated by the person whose name is on the card. Team members to whom you’ve assigned cards must activate their cards by logging into their individual KleerCard accounts.
No action is needed to activate a virtual card. Virtual cards are automatically activated as soon as they're created.
