Payment processing is the area where Content Shops differ most from any other shop; before the user can access Content, they must have paid in advance. Unlike, for example, a clothing shop, there is no breathing space before shipment to receive payment; payment must be guaranteed immediately before the user can gain access to the product.

Most online payments today are conducted by credit card, so web sites must be able to clear credit card payments immediately. However, there are many potential customers who don't own cards, or refuse to use them online, so alternate methods of payments should also be supported to maximise revenues.
