Apache::Centipaid is an Apache add-on module that allows content providers to collect small transaction fees (as low as $0.001) as payment for accessing parts of their Web site without changing their Web site design. The micro payment solution relies on Internet stamps for payment, providing a secure and anonymous method of payment. The module takes care of authorizing, accepting, and authenticating payments, as well as granting and disallowing access to users based on the payment information. It requires Apache with mod_perl support enabled.
