SMART BILLING SYSTEM USING RFID AND WEIGHT SENSORS

This paper presents an idea of a smart billing system that utilizes radio frequency identification and weight sensors with the billing side using PLX DAQ. RFID we can examine each and every product that is placed in the trolley and the products are displayed on the LCD of trolley. This helps to generate bill easily and huge number of customers can serve in a very short span of time. In this we use weight sensors to weight the products and sends the required information to RFID. After confirmation and payment of the products the information is eradicated from the microcontroller and makes the trolley available for the next customer. Therefore, the proposed model is low-cost, efficient and easy to use.
