Grocery stores now-a-days are crowded almost every hour of the day resulting in long queues at every billing counter. This paper is to develop an automated self-billing system that would save the customers’ time and would also be economic enough to be smoothly implemented. The authors propose the use of RFID technology and an Arduino board for the same. Every product will have an RFID (Radio-Frequency IDentification) tag (instead of barcodes being used conventionally). When customers have collected all the items they need to buy in their shopping bag, they simply place the bag on a self-checkout counter which is equipped with an RFID reader.
