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 method for recognizing end-users communicating with a computerized entity serving end-users via a plurality of entity/end-user communication channels, method comprising capturing personal particulars for each user from among a multiplicity of end-users via a first channel and storing the personal particulars in a corresponding multiplicity of end-user records in an end-user database, thereby to define a first, data capturing session for each of the multiplicity of end-users; and accessing at least one individual end-user's record during a second, data recognizing session, held via a second channel between the individual end-user and computerized entity subsequent to the first data capturing session therebetween, accessing including recognizing end-user by identifying the end-user record from among the multiplicity of end-user records which corresponds to the end user; and performing at least one of reading from and writing to the end-user record, wherein the channels comprise one physical channel and one on

Abstract: A mobile communication system comprising a multiplicity of mobile devices, and a server communicating with the mobile devices via a communication network, and a central database which is in data communication with the server and which is operative for storing sensitive data encrypted using at least one key, at least a portion of which is provided, only on certain occasions, by an individual one of the mobile devices and is not retained between the occasions by the central database.

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.
