People purchase different items in the malls and puts them in the trolley. At the cash counter billing process is done using bar code scanner. This is very time consuming process. To avoid this we are developed a system which is called as Automation of Shopping Cart using Smartphone. In this system we are using RFID tags instead of barcodes. This RFID tags will be on the product. Whenever the customer puts a product into trolley it will get scanned by RFID reader and product price and cost will be display on LCD display. Like this the process goes on. The trolley follows us without any human effort. We are using a GSM transmitter which will be at trolley which is used to transfer the data to Mobile. In Smart Trolley app, the amount will be sent and the payment will be done using mobile. If a person interrupts other than the user there is collision sensor to indicate. Key Words: Trolley, LiFi , GSM Module, RFID tag, RFID Reader, GSM Transmitter, ZigBee. 1. INTRODUCTION The barcode system is no longer the best way to business operation. Customers are tired of waiting in long, slowly moving checkout line in departmental stores, especially, in holidays. Now a days people are much attracted by the online trading because of tedious time consuming process at billing counter. People purchase different items in the malls and puts them in the trolley. At the cash counter billing process is done using bar code scanner. With the decrease of prices through efficiencies of technology and large-scale production of semiconductor wireless components, there has been a search for new markets in which semiconductor chips can be used. This has led to the use of RFID also known as smart tags. RFID stands for Radio Frequency Identification. Nowadays, if a consumer would like to buy something at a shopping mall, consumers need to take the particular items from the display shelf and then queue up and wait for their turn to make payment. The time taken for consumers to wait for the customers in front of the queue to scan every single item and then followed by making payment will definitely take plenty of time. Most consumers will worry the amount of money brought is not enough to pay for all the things that wanted to be bought until it comes to our turn to pay at the cashier. If the technology of RFID is implemented consumers will be able to get information of all the items at shopping mall, total up the prices of items as they shop, and save unnecessary time which is wasted unnecessary at the cashier. Currently available method in shopping malls is barcode method. In this method there are barcode labels on each product which can be read through specially designed barcode readers. A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuit to analyze the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port. 2. LITERATURE REVIEW Zubin Thomas, Nikil Kumar and D. Jyothi Preshiya(2016) had proposed that Automatic Billing System using Li-Fi Module will be the effective way to reduce the human effort . LiFi is cellular wireless networking (re)using lights. Specifically, light emitting diodes (LEDs) are used in LiFi as visible light transmitters. They proposed about the billing done by the Lifi device. The Lifi is a costly device which is not to be practically implemented in all malls, whereas the RFID is used instead of LiFi. Mr.P. Chandrasekar and Ms.T. Sangeetha(2014) proposed that automated billing system using RFID and ZigBee communication. Here, each product of shopping mall, super markets will be provided with a RFID tag,to identify its type. Each shopping cart is designed or implemented with a Product Identification Device (PID) that contains microcontroller, LCD, an RFID reader, EEPROM, and ZigBee module. Purchasing product information will be read through a RFID reader on shopping cart, mean while product information will be stored into EEPROM attached to it and EEPROM data will be send to Central Billing System through ZigBee module. From this, the idea of using a PIC Microcontroller instead of Zigbee has been utilized. Udita Gangwal, Sanchita Roy, Jyotsna Bapat(2013) proposed that Smart Shopping Cart for Automated Billing Purpose using Wireless Sensor Networks. In that, WSN for developing a Smart Shopping System which automates the entire billing procedure. The system which is developed is highly reliable, fair and cost-effective. It is reliable and fair because of the effectiveness of WSN combined with a highly Image Processing technique. The system also has energy constraint
