An Analysis of Li-Fi based Prevalent Automated Billing Systems in Shopping Malls

At mega malls, for grocery shopping and purchase of daily needs artefacts, customers have to wait in extended queues for the billing leading to wastage of their precious time. In order to solve this problem, Different researchers have proposed automation in billing system. When patron picks up an artefact and drops it into the cart, the scanner scans the artefact's distinctive code and its value, which is flaunted on the display screen of the trolley. After customer has consummate with the purchase, patron goes to the billing counter and pay the total bill which was shown on the display screen incorporated on the cart. In this paper, an attempt has been made to analyse the related works carried out by various researchers in this field based on the main components of smart cart like microcontroller, transmission medium and scanning system.
