Supermarket is where the customers come to buy their daily products and pay for the same. Hence there is need to calculate the number of products sold and their product price to generate the bill for the customer to be paid. Cashier’s desks are placed so as to collect the bill. Currently there exists many supermarket chains who are attempting to reduce costs like labor costs and also time of the customers. This can be achieved by replacing the existing system where many people work to collect the amount by new self-service check-out machines. Such machines involve only a single member who can handle many different machines at a time. The system provides centralized and automated billing system that uses RFID and Bluetooth communication modules. Each product of shopping mall or super markets will have a RFID tag which will help to identify the product type. Each shopping cart will be designed or implemented with a Product Identification Device (PID) which contains microcontroller, LCD, an RFID reader, EEPROM, and a Bluetooth module. Information of the product that is to be purchased will be read through a RFID reader on shopping cart, in the mean while that product’s information will be stored into EEPROM which will be attached to the cart and that data will be send to Central Billing System through the Bluetooth module. When the central billing system receives the cart information and data stored in EEPROM, then the system will access the product database and calculates the total amount to be paid for that particular cart. Main aim of the project is to generate automatic billing to avoid huge crowd or large queues in shopping malls and super markets.
