Smart Billing Trolley using RFID and Li-Fi

Abstract

 A progressive product is one that lessens manual labor and aids the society with increased comfort and gives a robust performance in everyday life. Such a product is appreciated by the society. Nowadays, buying necessary items at supermarkets and malls has been a daily activity in numerous cities. We observe tremendous rush at shops, especially in the vacation periods and at the weekends. This rush becomes gigantic during the period of various offers and discounts. On such occasions, customers purchase a variety of objects in the supermarkets and put them in a trolley. The very next thing they have to do is to find the specific product on the list, and a queue to pay at the billing counter. It is a tedious and time-consuming process. To avoid this rigmarole, we are growing a system which we have named as the ‘LI-FI Based Automated Smart Trolley’. In this system, we have used the RFID tags in place of the traditional barcodes. Every product has an RFID tag. Whenever the customer places a particular product inside the trolley, it is scanned through the RFID Reader. The weight and cost of the product could be displayed on a private computer. To implement this, we are using Visible Light Communication (VLC) technology to send the corresponding statistics to the central computer. At the billing counter, a Li-Fi receiver is placed, which is able to obtain the information from the Li-Fi transmitter linked to the RF reader
