Abstract: The contemporary electronic technology is based on embedded system which deals with integrating numerous transistors on a single silicon chip. The main goal of growing technology is to make lifestyles turn out to be simpler and more comfy. Nowadays, people like visiting shopping malls that are characterized by their colorful variety and heterogeneity besides beauty. A shopping center is where people can discover all kinds of shops including eateries and cinema under one roof. In shopping malls, people can purchase the groceries, fruits, etc., so it requires a trolley to carry the things they purchase. Every time consumers have to make some calculations regarding those items & need to compare them with their budgets. After this procedure, the customer must wait for the billing. So to avoid the boredom of waiting in the billing queue our research proposal has been carried out on a novel concept that is “Smart Shopping Using Smart Trolley”. In this proposed work uses RFID tags to be displayed on the product. Whenever the customer places a product in the trolley, the RFID reader will check it and the price and cost of the product will be displayed on LCD display. The main advantage of this work is that it provides for the caring of child that the customer may bring and so it has introduced a child unit. It comprises of RF module that is used as a transceiver and once the child moves away from the customer through the parent it may get some indication. When the child moves from the trolley through a certain distance, the LED which is placed in the cart turns off. After the completion of shopping, billing can be done using QR code that is pasted either on the trolley or at the exit point. 
Keywords: Child unit, LCD Display, RFID reader, RFID tags, RF module.
