The Internet of Things (IoT) is changing human lives by connecting everyday objects together. For example, in a grocery store, all items can be connected with each other, forming a smart shopping system. In smart shopping system an inexpensive Radio Frequency Identification tag is attached to each and every product. The customers are provided with a smart shopping cart, when the customer places the product into the cart the product details such as price, count, etc., can be automatically read by the RFID which is attached to the smart shopping cart. At a result, the billing is carried out by the micro controller in the cart itself and it can be viewed through the Liquid Crystal Display in the cart. The product details (count, amount, etc.,) are transferred to the Personal Computer Billing system through Zigbee connection thereby preventing the customers from waiting in a long queue at checkout of the shop. This project is aimed at developing a hardware-based system named Stock Management System called the Blynk Application for managing the stock system of any organization. This system can be used to store the details of the stock, stock maintenance, update the stock based on the sales details, and generate sales and stock report daily or weekly based. This project is categorized individual aspects for the sales and stock management system. In this system we are solving different problem affecting to direct sales management and purchase management. Stock Management System is important to ensure quality control in businesses that handle transactions resolving around consumer goods. Without proper stock control, a large retail store may run out of stock on an important item. Keywords: Smart Billing system, RFID tag, ZigBee, stock management system, Blynk.
