In the present day scenario, The Internet of Things (IoT) has taken the world by storm by simplifying our day to day
lives through integrating devices together. For example, In places like a supermarket, A smart shopping system could be created
by inter-connecting all ingredients and items with each other. Most IoT devices communicate through cloud or wireless services.
In a typical IoT system for SuperMarkets, a Radio Frequency Identificaton (RFID) tag is used to connect with each item or
product. This RFID tag is then attached to a shopping cart. When products are placed into it, The RFID reader reads the tag
implemented on the producted. This information is then passed onto the central server located at the checkout terminal. As a
result, Billing of items could be done from the shopping cart itself which saves time for the customers previously stuck at long
queues. This method could also be integrated for Inventory Management to monitor stock of the products and then notifying it to
the store managers .
