SHOPPING AND AUTOMATIC BILLING USING RFID TECHNOLOGY

Nowadays, large grocery stores are used by millions of people for the acquisition of products. Barcode scanners are a time consuming process engaging the customers to stick to the billing section for a long time. Hence there is a need for an innovative product with the societal acceptance that aids the convenience, comfort and efficiency in everyday life. In this paper, an architecture is presented which blends Radio frequency identification (RFID) and wireless technology to provide ‘on spot’ billing in super markets. It uses the RFID based system application in the shopping trolley and the RFID card which is used as a security access for the product. The Liquid crystal display (LCD) that is fixed to the trolley displays the product name, cost and the total cost of all purchased products. The bill is transmitted to the server end through the zigbee technology. The software simulation is done using Proteus software and hardware is implemented using 18F46K22 microcontroller. This promotes quick shopping and immediate pay without any queuing process. It reduces labour efforts and increases efficiency by minimizing errors.
