Abstract

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