QR Code Based Smart Trolley Using Mobile

Abstract

This paper provides a centralized IoT-based smart automated billing system using RFID. Radiofrequency identification  technology is used for supply chains, streamlining inventory, and shoppers swarms. Developed a Mobile app using Java and Python programming languages. The main aim of a mobile app to search the location of the product in the shopping mall using a shopping assistant which is available in the Mobile app. ESP8266 is a WIFI device used to transmit billing information to the cloud. And this device acts as an intermediary device for this project. Each and every product in the shopping malls will be provided with an RFID tag, to know the product information. After scanning the RFID tag the product information will be stored in EEPROM and the billing data will be sent to the cloud using the Wi-Fi device module. And then, it will access the database and it will calculate the total purchase amount of the particular trolley The main aim of this paper was to provide a QR code and IOT based automatic billing to avoid searching for the products and to avoid the queue in shopping malls and supermarkets.
