Abstract
The present system relates to an RFID based shopping system. The system comprises of an RFID reader and various RFID tags are attached to various products. When we go for shopping in supermarkets or malls we select different items according to our choice and put them into a cart and then go to the billing counter for payment, So at the end we get to know about the overall total cost of the products and for sometimes we also have to stand in a queue for a long time resulting in wastage of time for customers. It is needed to develop a system which provides comfort, expediency and efficacy during shopping. The system consists of a Liquid Crystal Display which is mounted on trolley for displaying the information of the selected product and total amount. On 4X4 matrix keypad buyer can set their budget amount for shopping, thus when the total bill amount. If the total bill amount increases than the set value then an alert is generated by the buzzer. After the completion of shopping one can pay the bill by pressing a button wirelessly. Therefore, the system expedites faster billing with reduced time.
