Abstract:An innovative product with societal acceptance is the one that aids the comfort, convenience and efficiency in everyday life. Shopping at mall is becoming daily activity in various cities. We can see huge rush at malls on holidays and weekends. The rush is even more when there are special offers and discount. People purchase different items in the malls and put them in the trolley. They have to find for the product on the list, queue to pay, at the billing counter. It is a time consuming process. To avoid this, we are developing a system which we called as ‘LIFI Based Automated Smart Trolley Using RFID’. In this system we are using RFID tags instead of barcodes. Each and every product has RFID tag. Whenever the customer puts a product into the trolley, it will get scanned by RFID Reader. The name and cost of the product will be displayed on the LCD. We are using Visible Light Communication (VLC) technology to transfer the data to the main computer. At the billing counter, LIFI receiver will be placed, which will receive the data from the transmitter.
