No! While you are asked by Kickstarter to provide your credit card details to Amazon Payments (the largest ecommerce site in the world, meaning they have been very careful over the years with people's credit information) no hold is placed on the amount you pledge. Your account will only be charged on October 15, 2014 IF our campaign is successful. At that time, your reward is secured. If our campaign is unsuccessful, then you will NOT be charged.
