Architecturing a Financial Services Transaction Engine

As mobile devices has become widely used, there is also an increasing economic interest in frameworks for service and product payment directly from mobile devices. Such a framework involves software applications running on the device itself. More importantly, the framework involves a flexible back-end in order to cover the wide range of possible transactions. The back end solution proposed in this paper consists in a generalized transaction engine which operates on abstract operations. The construction of the engine involves in the first stage the identification of the possible actors and operations which the system must support and in the second stage the formalization of a possible architecture for the engine itself.
