Electronic Commerce over the Internet is one of the most
rapidly growing areas in todays business. However,
considering the most important phase of Electronic Commerce,
the payment, it has to be noted that in most currently
exploited approaches, support for at least one of the
participants is limited. From a general point of view, a
couple of requirements for correct payment interactions
exist, namely different levels of atomicity in the
exchange of money and goods of a single customer with
different merchants. In this paper, we identify the
different requirements participants demand on Electronic
Commerce payments from the point of view of execution
guarantees and present how payment interactions can
be implemented by transactional processes. Finally, we
show how these execution guarantees can be provided
for payment processes in a natural way by applying the
ideas of transactional process management to an Electronic
Commerce Payment Coordinator.
