Supermarket Shopping System using RFID as the IoT Application

The objective of this research was to present the proposed design and use of an RFID technology-based smart shopping system. In this system, smart shopping carts that the consumers can navigate in their search for their desired items are used, while promotional items are also recommended, and the billing information will be calculated during the customer's shopping activity. The smart shopping cart will automatically identify the items placed inside and add them to the bill. Use of this method will allow shoppers to save time by avoiding the long lines at the check-out points, and the supervision of the supermarket will be more efficient. The number of products will also be updated and sent to the main server by the sensor on the shopping cart, so that the server will always be aware of the status of every item in the store. Moreover, the management of the inventory will be much more effective, as the RFID reader will automatically read all of the items instead of being scanned manually by an employee.
