Smart Shopping with Automated Billing System Using Zigbee and RFID

In the future, smart commerce will serve as a platform for smart cities. This method is fully automated, and billing may be completed without the assistance of a cashier. It is a mobile gadget that will be installed in the PICk and Drop basket (trolley) at department shops. Billing can be done via a swipe machine or by using their smart phones to access online banking. Instead of a bar code reader, we utilise RFID. Each item will be assigned an ID number, allowing for easy billing. In addition, the product update will be transmitted to the server. As a result, if any of the products becomes null, an alert will be sent to the main server or the master PC administrator. The bill will be sent to the customer's cellphone number through GSM. ZIGBEE is used to communicate from the trolley to the main server. We employ a PIC microcontroller in our suggested system, which is cost and performance efficient. The ultimate goal of this article is to automate billing and move India closer to being a Digital India. Time may be saved for the client, and manpower can be decreased.
