What does 'suspend card' mean?

If you notice unauthorized activity or are unsure of any transactions on your card and you want to safeguard your current balance, you can click on suspend card on your card's online portal. This will temporarily block your card from future transactions. 
The domain that your card uses is written on the back of the card. Not all cards have the same domain on which you need to sign in to. For virtual cardholders, please refer to the activation email that you received for the card. 
Keep in mind that this feature will still allow all credits or returns into the card, however you will not be able to process any transactions on this card.
To unblock or unsuspend your card, simply click the "suspend" button again and you should be able to use the card as usual. If you require any clarification or assistance, please contact the number on the back of the card or email us at help@mycardholdersupport.com
