Smart Cart Obsonium based on Secure System

Nowadays IoT has its influence over every sector of life ,striving hard to improve quality of life. Obsonium is a never ending business and to improve the quality of obsonium we can take the help of technology. In today’s technology, many companies are developing products that ensure convenience toward all people who needs a good obsonium experience from today’s hectic obsonium which takes a lot of time for billing and getting out. Thus, we have developed a Smart Obsonium Cart, that allows faster check-out. First the product will have a RFID card which will filled first by shop Admin with other de- tails of the product. Then cart uses the RFID reader technology to identify the products details which is already available in the database. The total cost will be displayed on the mobile attached to the cart as and when the product is added to the cart. The user can view the details of the product on his mobile. IoT helps to design such a cart which will automatically scan the product and add the respective amount to be paid in the bill on our own smart phone itself. Technologies used in this system are RFID tags and RFID reader for fetching the price of each unique item. Arduino microcontroller to perform the sum of the prices of the products and to prepare the final bill. Mobile application for the final display of bill and the complete obsonium list. Security is provided by the weight scanner and validating the products bought to avoid tag tampering. All the item’s information is stored in the cloud at first. Checkout verification is also done by passing the cart after payment through a lane with RFID readers.
