The invention provides a multi-terminal cashier
system, and belongs to the technical field of communication, the multi-terminal cashier
system comprises a terminal sales end and a background management end, the terminal sales end comprises a double-screen all-in-one
machine, a
user equipment end and a self-service terminal; the background management end comprises a promotion module, a commodity module, an order module and a settlement module, the promotion module is used for storing promotion rules and executing rule calculation, the commodity module is used for commodity management and
inventory management, the order module is used for creating orders and managing sales delivery, and the settlement module is used for settlement. The settlement module is used for creating a
payment order, paying an order and
processing financial transfer; through API interface communication, real-
time data synchronization of the terminal sales end and the background management end is realized. By constructing a real-
time data synchronization architecture of the multi-terminal sales terminal and the background management terminal, the technical problems of non-
cooperative interaction of multiple terminals, low calculation efficiency of promotion rules, long fund settlement period and the like in an existing retail cashier
system are solved.
