Abstract: This invention discloses a novel system and method and system for sharing a data item among a plurality of computers connected in an arbitrary network topology. In the preferred embodiment, each of the plurality of computers has a local copy of the data item, but can only edit the copy by obtaining a token from the current token owner, thereby becoming a new current token owner. When the token owner makes a change to the data item, the change is broadcast to the other computers, along with the identity of the new current token owner. Routing of token requests and broadcasts is accomplished by means of each computer calculating a routing table based on information it receives from those computers to which it is directly connected on the network.

Abstract: This invention discloses a novel system for securing and using payment token data in a system for processing electronic payment transactions that does not require down-time for rekeying encryption keys when the keys are rotated.

Abstract: This invention discloses a novel system and method for providing retail point of sale terminals that are connected securely over the Internet to a back-office service that manages the retailer's data as a service using a system that supports more than one retailer, each of which will have one or more point of sale terminals. The system is adapted to provide transaction reconciliation with an accounting system whenever a user ends a shift and logs out of the register instance they are operating.
