Abstract: Microcontroller based design has acquired the status of the most happening field in electronics. This is the highly specialized field that has the power of integrating thousands of transistors on a single silicon chip. Nowadays, in the mall for purchasing variety of items, it requires a trolley. Every time customer has to pull the trolley from rack to rack for collecting items and at the same time customer has to do the calculation of those items and need to compare it with his budget in a pocket. After this procedure, the customer has to wait in queue for billing. So, to avoid a headache like pulling trolley, waiting in billing queue, thinking about budget, We are introducing a new concept that is “SMART TROLLEY IN MEGA MALLâ€. In the modern era, for automation of mall, we are developing a microcontroller based TROLLEY which is totally automatic. It follows the customer while purchasing items and it maintains a safe distance between customer and itself. The customer has to hold the barcode side of the product wrapper in front of barcode scanner. Then corresponding data regarding product will be displayed on display. By using this trolley, the customer can buy a large number of products in very less time with less effort. At the billing counter, the computer can be easily interfaced for verification and bill print out.
