Robust Low-Cost Passive UHF RFID Based Smart Shopping Trolley

Retailers are often interested in low cost mechanisms to maintain stocks as well as for tracing products across the supply chain in an efficient and effective manner. In addition, shoplifting is another concern faced because of the lack of effectiveness in product tracing technique such as “barcode” used in retail super markets. “AmazonGo” a smart retail layout which was introduced by Amazon, to address above issues was found to be inefficient due to the over dependency of system based on historical purchased patterns of consumers. In this paper, we propose a low-cost, robust, passive UHF RFID based shopping trolley system which allows tracing and processing shopping data in real time. The UHF antenna mounted shopping trolleys are defined “Smart Trolleys” while shopping items are tagged using UHF RFID tags with unique identification codes.
