Implementation of smart cart in retail marts using RFID tags and Wi-Fi module for fast bill generation

Abstract

In the contemporary world shopping plays a key role in our daily life. The retail marts is the place where all the commodities, basic necessities of the consumer are readily available and lot of people are willing to go to retail marts for shopping. So with the increase of crowd in the retail marts generating a bill to the customer is taking longer time. This paper proposes a Smart Cart (SC) sensor based system for fast bill generation in retail marts. The Wi-Fi module using in this SC is very flexible to use and it operates under the frequency band of 2.4-5GHZ with an operating speed of 55 Mbps and covers a long distance with the support of WLAN. An SC prototype has been developed by incorporating the required sensors to the cart (a box attached to it). The implementation of SC requires components such as ATmega328microcontroller, LCD Display, ESP8266 WiFi-Module,EM18 RFID Reader, Passive RFID Tags.
