As a leading brand of IPC in China, North China Industrial Control Co., Ltd. has tailored the embedded CPU card POS-6921 for the POS industry in response to the performance requirements of the POS industry. The integrated functions of this board are quite complete and the stability is high. , It has been favored by many POS equipment manufacturers.
In order to strengthen the management of its supermarkets, strengthen internal control, improve overall work efficiency, save labor costs, and quickly obtain correct decision-making information, a large supermarket chain group in Shanghai aims to achieve the core capability of accelerating capital turnover and enhancing corporate competition. Imported POS equipment was upgraded and a complete information management system was established.
A POS equipment system integrator in Shanghai provided a full set of equipment solutions and obtained approval to build the project. The POS-6921 CPU is used as the core of the cash register. System topology:

Application prospects:
The wide application of POS (Point OF Sells) in specialty stores, supermarkets, and department stores has enabled the entire POS industry to show a good development and product features are not perfect, but the market share of domestic products is not high. Urgently resolved. The POS special board launched by North China Industrial Controls provides a more complete solution for the localization of POS equipment. It will certainly boost the domestic market share of POS equipment manufacturers and improve product performance.
PLC Splitter is based on planar Lightwave circuit technology and precision aligning process, can divide a single/dual optical input(s) into multiple optical outputs uniformly and is denoted 1xN or 2xN .
