IoT Based Automatic Billing System Using Barcode Scanner by Android Device and Monitoring Unregistered Barcode by RFID

In all over the world India is the second largest populated country. People here like to shop their daily needs in malls because of the quality of service they provide to the consumers. The main problem that we face here is having to wait for long queues even to bill one or two products or at times there might be problems with several other billing counters which would temporarily be out of service and all must go through the billing process only at one remaining counter. In this paper, we will discuss about the solution for various problems arising in the malls such as time consuming while billing, miscounting, thefts and other such discrepancy. We are implementing an automatic billing system which helps us to solve all the problems as mentioned above with the help of RFID scanners and detector for scanning of products and prevention in theft and IoT for data management purpose. It not only makes the billing system easier, it also helps us to transmit billing information to customer's mobile and automatic detection of amount from their interlinked bank account.
