Kickstarter is ditching Amazon Payments and moving to Stripe:

The move should help Kickstarter in a few ways. Its project creators should be able to get up and running more quickly — they previously had to set up a business account with Amazon, which could take up to seven days for approval, before launching a Kickstarter campaign. Kickstarter campaign backers can also now make their pledges in fewer steps, since they won’t have to leave Kickstarter to pay on Amazon (Kickstarter was using a legacy Amazon Payments product that didn’t allow this; Amazon’s new payments product does). Lastly, Kickstarter can use Stripe to process all the transactions on its platform, both in the U.S. and abroad. Amazon Payments’ lack of international support forced Kickstarter to use another payments processor for overseas campaigns.
I’ve successfully funded two Kickstarter projects (here and here) so anything to make things easier for backers sounds good to me.
