I will sign you a check for... PS: Where do we send our wish lists and funds?
Kickstarter doesn't work like that. You must use a credit card (Visa/Mastercard/etc). The payment is processed through Amazon.com so it defaults to your Amazon.com stored credit card information (you do have the option to use a different credit card). You get charged at the end of the project funding window if the overall requested amount is met.
