There also is the Amazon Honor System.

What Is the Amazon Honor System?
The Amazon Honor System is a safe and easy way for you to support your favorite Web sites and to buy digital content on the Web. Amazon.com has successfully completed hundreds of millions of online transactions and has more than 25 million customers. Now, the Amazon Honor System lets you use Amazon.com payment technology to make payments to Web sites as small as $1.00.

Web sites use the Amazon Honor System to collect voluntary payments from their users and to accept payment for digital content. In many cases, the Honor System is the only way a Web site can economically collect small payments. In others, the Honor System allows the Web site to raise money for continued operations without resorting to intrusive banner advertisements.

When you visit a participating Web site, you'll see an Amazon Honor System paybox. Click on the paybox's "click to pay" or "click to give" button to view the Web site's PayPage at Amazon.com. There, you'll learn more about the participating Web site and its reasons for collecting money. To make a payment, click Pay now on the PayPageTM, and rely on Amazon.com to complete the transaction quickly and securely.

I had to find an alternative to PayPal after they blacklisted me. I had a site where I was accepting donations and I had images up for a contest a radio show was having for girls with the nicest breasts. They accused me of taking payments for a porn site and I have been blacklisted since.
