Pay Per View (PPV) is a transaction handling protocol for use on the World Wide Web (WWW) developed in 1995 as part of the NetCash and NetCheque® payment systems. Using PPV, merchant WWW servers can make certain documents available on a pay-per-view basis. PPV is built on top of ARDP and HTTP for transport, and the software developed for PPV accepts both NetCheque and NetCash payments.
When installed with PPV, a merchant server answers an HTTP request for a pay-per-view document with a preview of that document, as well as payment information and options. The client software, at the direction of the user, prepares payment for the actual document, and passes this payment to the merchant, at which time the document is returned to the WWW browser. Features of PPV include support for most MIME-type documents, real-time payment verification, flexibility of payment and transfer methods, and encryption options for payment instruments.
