Operational Details
In order to take advantage of the service, the merchant adds a
small HTML fragment (supplied by CSN) to their web page. In the simplest scenario,
the fragment encodes the cost of the purchase plus 2 URL's corresponding to 'Order
Accepted' and 'Order Declined' respectively.
If necessary, the client increases their balance by making payments via any of the
available methods, e.g. PayPal or Credit card - if multiple payments are made, these
are added together to the clients balance. Once the balance reaches the purchase price, the price
is subtracted from the balance and the client is invited to proceed with the purchase.

Payment using a telephone callIn this case, the client can simply dial a Premium Rate telephone number whose number is displayed by their browser. An automated voice response system continuously reports their Account balance to them over the phone (it can also be viewed on the web site). Other Payment MethodsCSN also provides other means for 'charging up' the client accounts, for example via a Credit Card, PayPal and so on. Purchase of Online Content by a ClientIn many applications, there may be no physical goods to be sent to the client. For example, the 'Goods' may be an MP3 file or access to a high-value database, e.g. company details or financial and legal information. In this case, all the Merchant has to do is edit the link that would normally point to the Content so that it includes the payment required. When the client clicks the link, eVopay makes the charge on behalf of the Merchant and then redirects the clients browser to the Merchant's content page. Client AccountsAlthough the initial emphasis is on 'single use' applications, once the software is installed on the clients PC it makes it easy for them to purchase other goods and contents using the same scheme. Other ImplementationsNote that the above operational details covers a relatively simple implementation - there are many options and variations which are not covered here for the sake of brevity.
