IoT Applications on Secure Smart Shopping

We propose to design a smart shopping system based on RFID. The smart carts used in such a system can navigate the customers to the desired products, and they can calculate the billing information as the customer shops. Items that are put in a smart shopping cart can be automatically recognized and billed. In this way, customers can avoid long queuing time at the check-out points. The grocery management also becomes much easier: The sensors on the grocery shelf can keep updating the number of items to the central server so that the server is always aware of the items' status in the store. Furthermore, the inventory management also becomes much easier, because all the items can be automatically read by a RFID reader instead of manually scanned by a laborer. In this paper, we propose a smart shopping cart system with consideration of how this system can work functionally and securely.
