Patent ID: 10607202

Abstract:
A synchronization system for fulfilling orders under non-persistent network conditions includes point-of-sale (POS) terminals and a server. Each of the terminals generates changes corresponding to one or more orders, queues the changes in order queues that correspond to the one or more orders, and transmits the changes in the order queues, from oldest to youngest, when operably connected to a network, where one or more of the terminals operably connect to the network by tethering to a cellular equipped device. The server receives the changes and transmits the changes to the terminals. The server has a queue processor that queues the changes in terminal queues that correspond to the terminals, where the changes are transmitted to a first one of the of terminals, from oldest to youngest, when it is operably connected to the network, and where the state changes are maintained in terminal queues corresponding to other ones of the terminals while the other ones remain operably disconnected from the network.
