Advancement of Shopping Handcart for Supermarket

The supermarket is a place where a wide assortment of products is accessible. The primary expectation of markets is to give accessibility of the considerable number of products and spare the hour of the buyer. As innovation advanced, lives have been essentially improved because of the development of laborsaving and intelligent utilities. In urban communities, we can watch a colossal blaze at the supermarket on weekends. This turns out to be much more when there is an assorted variety of offers and discounts. In the current scenario, people purchase an assortment of products and put them into the cart. After taking the desired products, one should move toward the counter for billing. Manual billing takes ample time which results in hauling the shopping handcart all through the shopping time and holding up in huge queues at the billing counter. To conquer these difficulties, we have proposed ARM-7 microcontroller-based smart shopping handcart for supermarkets to make the shopping experience very convenient for customers. This work can potentially reduce the human efforts and manpower requirement at the billing desk. Radio frequency identification (RFID) reader helps to scan through the tag and display the product information on LCD screen. ZigBee serves as the transceiver. All the components are interfaced with microcontroller which has database of the particular product in its memory. So whenever a tag is swiped the microcontroller checks the database and displays the details of the product. At the final stage, the list of details of the products is maintained and convenient payment solution is provided when shopping is finished. The goal of this task is to improve the speed of shopping. Hence, this system provides time-efficient, cost-effective, convenient, reliable, and user-friendly solution for shopping.
