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.
