The Modern technology in electronic is embedded systems Arduino based micro controllers. One of the important aspect of science is to make easier to our lives and Radio Frequency Identification(RFID) an innovative technology concept which is used for the implementation of an Intelligent trolley and smart billings. The issues that can be faced by customers while shopping is:  Standing in long queues at the billing counters and Wastage of valuable time. People buy the products from a shopping mall or complex for their regular use. So, that the customers visit the shopping malls most of the times and they spend hours together waiting in a queues for paying the bills, this is because of scanning the product with the help of barcode which takes more time at bill counters.As to avoid this problem here we are having a technology called Radio Frequency Identification(RFID). The smart trolley system consists of an Arduino based micro controller, an electronic display i.e., Liquid crystal display(LCD), RFID Reader, RFID tags whether it may be a stickers or it may be a card. Whenever, a customer puts a product in to the trolley the RFID reader reads the code present on a tag or card. After that the product name, price of the product will be displayed on LCD, and this data can be transmitted by ZigBee from trolley to the main server i.e., the PC which is present at the bill counter.
