Abstract: A computer-implemented transaction routing system including: a rule engine operative for receiving a flow of transaction data entities, using a processor for applying pre-imposed routing rules and determining routing of each data entity for which at least one pre-imposed routing rule is true to an external payment processor selected using the pre-imposed routing rule; and a transaction processing analyzer operative to accumulate data characterizing current handling by respective payment processors of at least transaction data entities routed to the respective payment processors by this system to maintain, by using a processor to compute, from the data, current statistics quantifying at least one handling aspect quality characterizing each of the plurality of supported payment processors, and to route at least each transaction data entity for which no pre-imposed routing-rules are true to a “best” payment processor selected by applying predetermined aspect combining criteria which prioritize the aspects to the

Abstract: A system for displaying computerized invitations to end users, the system including an invitation server, networked to a multiplicity of end-user's browsers via a network, and operative to send a response to an individual end-user's browser, wherein said response is operative to command the individual end user's browser to: a. open a window on top of publisher content previously selected by the individual end-user and currently present in user's browser; b. display, inside the window, an invitation including invitation consummation information allowing the individual end user to consummate the invitation, and c. close the window once the individual end user consummates the invitation, thereby returning her or him to said publisher content previously selected by her or him.
