What happens if a backers credit card is declined?
If a credit card is declined, an email is sent to the backer every 48 hours with a link to fix the issue. The backer has seven days to correct the problem. If they do not correct the payment during that seven day period, they are dropped as backers from the project and are no longer eligible to receive rewards. You can view the status of all your backers on your Backer Report.
