Implementation from your point of view is very simple, as the interface
is just a normal <FORM> element on a standard HTML page. We take care
of all the security aspects, while maintaining the 'look and feel' of the
merchant's site across all stages of the payment process.

The benefit for you is that by using the standard DirectOne interface they
can get real-time payment processing with no software to install or maintain.
This means they can choose almost anything as their shopping cart application,
from iNetStore, Miva, ShopSite Pro to EziMerchant and can get the process
completed within a couple of hours, rather than the normal few weeks.
Any merchant using the Spirit Servers Enterprise and Daimond DirectOne Packages
is automatically certified, allowing new merchants to skip the usual certification step.
