Keywords: embedded system, point of sale (POS), remote monitoring, cloud service, cash register management system

Electronic scales and cash registers play a universal role in transactions at the checkout systems of businesses. To reduce the number of errors occurring at the checkouts of buffet restaurants using electronic scales, a novel electronic scale measuring system is designed and investigated in this study. This designed checkout system was constructed using a Tibbo embedded chip in the cash register management system with a cloud connection. This proposed system is different from the point of sale (POS) system: it can obtain all the information of sale items at the same time, and it has the advantages of a low cost and simple operation. Furthermore, the system can transfer each trading record to be saved in a remote server through a cloud transfer service, and restaurants using this system can construct an effective accounting management mechanism. A weighed quantity is transformed into a digital quantity and sent to the cloud system by the embedded system. As compared with traditional, expensive, and large POS systems, the proposed system has higher measuring accuracy and is less affected by staff errors. The low-cost cash register management system with a cloud connection will be a competitive digital product for future commercial business activities.
