An RFID reader with electronic hardware system is fitted with the trolley to make the purchase comfortable. Those items which are above the particular amount are fixed with the RFID card whose price is fixed into the reader. When item is shown in front of the reader, the amount of the item is added to the purchase bill, and is shown on the LCD display. The trolley is programmed in such a way that it will find the rack number displayed on the LCD. It also has the provision for removing the items from the trolley where the cost is removed from the total cost .Once the items are added, the cost is added up and when it crosses the certain limit, it gives an alarm signal to indicate that the customer budget has exceeded. All this information is send to a computer for billing update through wireless link called Zigbee network, which facilitate the billing system even faster and reduces time. Key Words: RFID reader, RFID card, LCD display, Zigbee network. 1. INTRODUCTION Shopping mall is a place where people get their daily necessities ranging from food products, clothing electrical appliances etc. Nowadays a number of shopping mall has increased around the globe. Sometimes customers have problem regarding the incomplete information about the product on sale and waste of time at the billing counters [1]. Continuous improvement is required in the traditional billing system to improve the quality of shopping experiences to the customers. To overcome these problems and to improve existing system, we have designed an RFID based shopping trolley. This can be done by attaching RFID tags to the products and a RFID reader with a touch panel display on the shopping trolley. With this system, customers will have information about the price of every items that is scanned in, and total price of the item. This system will save the time of customers and man power required in mall and cost associated with the product. The advent of newer techniques like RFID technology and wireless networks have makes the process of shopping at a faster pace, making it more efficient as well as making it more transparent [2] .RFID tags are nothing but small transponders, communicates to a reader wirelessly by transmitting some identifier such as serial number .By constructions, they are the special type of wireless cards which carries built-in embedded chip and loop antenna. The chip represents a dual digit card number. The RFID reader circuits generates 125 KHz magnetic signal. RFID tags have been widely used to track items and label them in various shopping destinations like supermarkets. They are treated as advanced form of barcode. In existing system, shopping malls are using barcode standards [3]. The cashier in billing system scans the items using the barcode scanner and gives us the total bill. And the customer can gather the items they want, put it into the container and at the time of billing only. They come to know about the total cost. Hence they need to stand in a larger queue of billing those items. RFID and barcode are almost similar. They are both data connection technologies that mean it will automatically process the data. However they differ in many areas. RFID can be read without the line of sight, whereas barcode requires a line of sight to read. Barcode scanner requires a manual tracking, whereas RFID can be automatically tracked [4]. In case of barcode scanner, new information cannot be updated. Whereas in case of RFID, new information’s can be overwritten.
