TinyPass is a simple, powerful service that allows any online publisher to easily accept quick and secure payments for access to any type of content. TinyPass can process payments as small as 10 cents, and doesn't require changing your site's existing structure or layout.

You can use TinyPass to charge for access to a single post or a bundle of posts. TinyPass also allows you to offer discounts to those visitors who choose to purchase multiple posts.
