This article introduces the integration of a trolley with a smart phone and Arduino to increase the shopping efficiency for customers who patrons the supermarket. The article also discusses the benefits it brings to the different stakeholders of the smart trolley. The system utilises the user’s smartphone to scan for items, where the name and cost of the item will be reflected on a liquid-crystal display (LCD). A radio-frequency identification system is implemented to detect for membership. By tagging an RFID tag on the membership card and placing a RFID scanner on the trolley, members will be detected when they are nearby. After shopping, the customer can transfer the bill to the checkout computer. However, the smart features are exclusive for members only. Patrons without the membership card are limited to a normal trolley without the smart features. The article also mentions the platform they make use of to run the software of the system and explain the procedure of the program. Furthermore, creating a barcode to scan is more economical and efficient as compared to RFID tags.

This article provides useful insights for our research project on improving shopping efficiency with a smart trolley. Like our research project, this article has the same purpose of enhancing patrons shopping experience. By integrating a trolley with an RFID system, they are able to improve the shopping efficiency of shoppers. While the article mentions the use of barcode scanning as their main approach to promote efficient shopping, it still provides us with useful information such as the smart checkout and exclusive membership system that we can apply to One-Stop.
